UPDATED: 08-22-2017 – Here is the ultimate answer to your question on how to install Remix OS. I came up with various methods of installing this beautiful Linux-kernel based Operating System. This includes methods from the official site, along with other methods that some folks aren’t covering yet. You need to be a little tech savvy to follow on with this guide.

Confirm that the USB drive will lose it’s data and enter the Admin password when asked; Disk Utility will now create a bootable OS X Mountain Lion installer drive out of USB drive using the disk image, this can take a little while depending on how fast the drive and Mac are but 20-30 minutes isn’t unusual.

• Also, installing to an HFS+ volume will require commenting out the usenvram false line in refind.conf if you want to hide boot tags or rely on rEFInd's ability to remember its last-booted OS. Warning: MacOS 10.11 ('El Capitan') implements a new feature called System Integrity Protection (SIP; aka 'rootless' or 'CSR').
• OS X 10.6 Snow Leopard was the first OS X version with optional support for a 64-bit kernel, allowing booting either with a 32-bit or 64-bit kernel. However, Apple did not support booting the 64-bit kernel in Macs that shipped with EFI32 firmware, even if they had 64-bit processors capable of running the 64-bit kernel.
• To install Remix OS on a USB Drive, simply follow the steps mentioned above. Simply select USB drive as your Disk Type, then select the drive letter for the USB. See reference image below. Uninstall or Remove Remix OS. I’m sure most folks out there will ask this same question after trying out Remix OS on their Windows machine.

Most tutorials out there, either written or video guide, usually covers the official and usual way of installing Remix OS on a Desktop PC. But with my post today, I’ll be covering different methods of Remix OS installation. This includes; direct hard drive installation, USB, VirtualBox, Dual-boot or Stand-alone type of installation.

So if you really want to learn how you would do this, you need to be patient and should read this guide word-for-word to fully understand and install Remix OS successfully. I highly recommend that you follow the same setup or environment as what I’ve used in this particular post.

What is Remix OS

Remix OS – is an Android™ OS for Desktop PCs, that support Legacy BIOS and UEFI boot methods. You can also run the OS on ARM devices. As of Saturday, 03 December, 2016 – Remix OS with Version 3.0.207 is now powered by Android™ Marshmallow.

With this Operating System, you can run any of your favorite Android Apps right on your PC. You don’t need to install another software or emulator just to run your most loved Android apps.

Game or productivity apps, you name it, it can run on your Desktop. No need for that sluggish and bloated software like BlueStacks – sorry no offense, but this is how I felt for this software.

FYI, BlueStacks is an Android emulator for PC.

This OS was created by Jide Technology – a company founded by three ex-Google engineers, to fulfill the goal of unlatching Android’s potential in this era of computing. Later, the Jide team was joined by Android-x86 founder, Chih-Wei Huang as x86 Technology Lead. In case you didn’t know yet, the Android x86 project is an Open Source project that ports the Android OS to Desktop PCs. That said, Chih-Wei Huang should play a vital role in the further development of Remix OS.

Why You’d Want To Use This OS?

Well I’m not saying this for everyone, but I should say that Remix OS is fast and efficient. I don’t have the numbers or benchmark score, but I can say that this OS is fast. You can install it on an old PC laying around and still you can feel the difference compared to Windows.

I’ve tested this on a Virtual Machine with 1GB of memory, and still this OS was responsive. Except when I launched several Apps at the same time, it becomes sluggish and almost hung up. Of course that is due to memory starvation. But what I’m trying to prove is, the interface itself is very responsive. I’m on a Linuxmint machine that I use everyday, and I usually notice a slight delay when launching Chrome, my file manager Nemo and some other Apps that I use everyday.

Also, why you wanna use this is because of Google Play. I mean come on… Android has thousands of FREE Apps at your disposal, and you can use and download these in Remix OS. Fan of COC? Well you can perfectly run this Android game on your PC, bigger screen!

And if you compare Remix OS against other alternatives out there (Android-enabled devices or softwares), still it beats the crap out of them. See image below to show how fast Remix OS run, on an Intel i5 processor.

The screenshot above shows the speed gaps between BlueStack 2 on i5, Samsung Galaxy Note 5 and other devices, which can obviously seen on the photo. The photo by the way is a screengrab from Remix OS‘ website.

My second consideration is ease of installation and use. Unlike Windows, you can use this OS right after you have installed it. You don’t need to install additional drivers or softwares just to tell that it is operational.

If you need additional apps, just launch the Chrome browser and search for the app you would want. Or use the Google Play menu, like you always do on your Mobile, to search for your favorite apps.

Another consideration why I would want to use this, is because it’s FREE. Yes, it is! Unlike Windows (comparing free vs paid), that you got to have a license for it to be installed. Not unless you’re a pirate and fond of using pirated copy of this OS along with malware/spyware installed with it. Take note though, that some Apps are not free. Especially those premium Apps and Apps with “In-App Purchase” feature.

You could actually use this OS in an enterprise environment like; Call Centers, Offices or Educational Institutions. You can set this up on a cheap ARM devices and mount it behind a LCD screen. Have you seed one of those setup? I like to setup one, but don’t have the right budget for it.

Now, here comes the nitty-gritty part of this post. Check further below.

Official Method of Installing Remix OS

I know this method has been covered several times already and posted all over the Internet.

But for the sake of this tutorial, I’m going to cover this and should be explained step-by-step to help my fellow noobs out there.

Noobs, be proud and follow this guide.

Note: Official method lets you place Remix OS on your hard disk as a Dual-boot with Windows 7, Windows 8 or Windows 10 and on a USB 3.0 Flash Drive.

Jide Technology recommends USB 3.0 for better performance. USB 3.0 performs faster than USB 2.0 in terms of transfer speed (640MBps).

I was able to run Remix on a 32GB and 8GB without issues. Only thing is, it takes a while for the first boot (15-20 minutes).

For Hard Disk Installation – Windows Based

The current installer tool supports Windows 7, Windows 8 or Windows 10, no Mac or Linux support yet. You need to have at least 8GB of hard drive space.

Note: You really don’t have to create a separate partition or dedicated hard drive for this install method. Why so? Because Remix will just copy the image file to a folder in your Windows C: drive, along with the necessary files on the other parts of the drive. Fairly simple to install. You can easily remove/uninstall it later when you need to.

Installation Overview

1. Download the zipped package for Remix OS. This includes the Remix OS ISO file and the .exe Install Tool.

   Sample file names:

   • Remix_OS_for_PC_Android_M_64bit_B2016112101.iso
   • Remix_OS_for_PC_Installation_Tool-B2016080802.exe

2. Run the exe installer tool and follow the instructions to install Remix OS on your PC’s hard drive.

3. Reboot your PC.

   For UEFI, press special key (F12 for Dell, F9 for HP, F12 for Lenovo, Option Key for MAC) while booting to enter boot menu and ensure that Secure Boot is disabled.

4. Select Remix OS from the Windows Boot Menu – Installation should continue in the background.

The Step-by-step Guide

Here comes the action.

Step 1: Download and Extract Remix OS

Download the package from this page and extract somewhere convenient on your hard drive.

You should see several files after extracting the zip file. In my case, I’ve got these:

• How_to_launch_Remix_OS_for_PC.txt
• md5sum.txt
• Remix_OS_for_PC_Android_M_64bit_B2016112101.iso
• Remix_OS_for_PC_Installation_Tool-B2016080802.exe

Note: You should have disabled Hide extension for known file types in Folder Options menu, under Windows OS.

Step 2: Launch the Installer

Run the exe installer tool and follow the instructions to install Remix OS on your PC’s hard drive.

You could right-click on the .exe file and choose Run as administrator or simply double-click the file to run it, then choose Yes on the next pop-up dialog.

You should now see the Install Wizard window, you should browse to the Remix OS ISO file, and choose Hard Disk for Type. Target drive could be C: (yes folks!) or another unused partition on your hard drive.

If you wonder why install Remix OS on C: drive? Well, with the installer tool, it is safe to install on the same partition as Windows sits on.

Why so? Because Remix OS will create a folder for itself, for its exclusive use. It will not overwrite any of the Windows files nor wipe out your existing partition. Remix OS will create a virtual file system in the form of data.img file. This file should contain your “Internal Storage” device – that appears as storage in Android devices. So it’s perfectly safe to use the C: drive, provided that you have enough space for Remix OS to use. You could use a 32GB, 16GB and 8GB as storage device, the install should prompt you to choose one.

Checkout how easy it is to remove/uninstall Remix OS, using this guide.

Screenshot – Remix OS Windows Installation

Click OK, and you should be able to choose your System Size, depending on your free hard disk space, you could choose from; 8, 16 or 32GB system size. If you have the sufficient space, choose 32GB – which is the recommended one.

Click OK again to start the install process. Once done, the Wizard will prompt you to reboot.

Reference Image:

Note: You can actually choose C: drive, it’s safe to do that, since Remix OS will copy the files to a directory name RemixOS.

Step 3: Reboot your PC.

For UEFI, press special key (F12 for Dell, F9 for HP, F12 for Lenovo, Option Key for MAC) while booting to enter boot menu and ensure that Secure Boot is disabled.

Once you get pass the POST section of the boot sequence, you should get a Windows Boot Manager menu looking like this:

Screenshot – Windows Boot Manager

Step 4: Now select Remix OS and hit ENTER key.

You should now see the boot logo with black background and white text. This might take a while, but once you get pass this screen, you should be prompted to select your preferred language. See image below.

Follow the rest of the prompt; agree to to User Agreement, Setup WiFi (or Skip this), add some of your favorite apps, then agree to Activate Google Play.

And that would be it! You should now installed Remix OS alongside Windows as a dual-boot system.

Very simple process and not too challenging, right? Right!

But what if you want to use Remix OS as your core OS, leaving you the question…

How to install Remix OS as my primary or standalone OS?

Well, you’re just in luck! Because the guide is actually included in this post. Read on.

For USB Installation – Windows Based

To install Remix OS on a USB Drive, simply follow the steps mentioned above. Simply select USB drive as your Disk Type, then select the drive letter for the USB.

See reference image below.

Uninstall or Remove Remix OS

I’m sure most folks out there will ask this same question after trying out Remix OS on their Windows machine.

How to uninstall/remove Remix OS?

To remove Remix OS from your system, simply run the UninstallRemixOS file from C:RemixOS folder. It should delete the files and the entry from the Windows Boot Manager.

Then delete the data.img file, along with the .disk folder. This should free up the space consumed by the OS.

Reboot your PC and done!

Single-boot or Standalone Installation

Actually this is not an official guide for installing Remix OS to hard drive without Windows. Jide Technology recommends to use the installer version, which let you install ROS alongside Windows 7, 8, or 10. But if you want to follow on, then let’s get started.

This is for a single-boot only install method. You need to use the .iso file that came with the downloaded .zip file.

Single Boot Requirements

• You need a separate HDD – or better of, another set of PC.
• You also need a 3rd-party partitioning software – This doesn’t need to be a paid or commercial one. You can download free tools like Hiren’s Boot CD. It’s a live CD ISO which you can use to partition/format your hard disk in preparation for the OS installation. You could use similar tools if you want.

• Burned ISO for Remix OS 3.0 64-bit – Build No. B2016112101 – or you can use the most recent one. But for the sake of this guide and to avoid issues, please use this build. Burning the ISO to a physical CD is beyond the scope of this guide.

• USB Drive if you don’t have a CD Burner. Use Rufus to write the ISO to USB.

• PC with Legacy BIOS – yes, I am still using this. For UEFI users, I am not sure if this guide would work for you.

  Note (Added on 08-22-2017): I’ve tested the 64-bit Package version 3.0.207 on my Legacy BIOS enabled system, powered by AMD Sempron, and it did not worked out of the box. I got the Remix OS Black Screen Issue. The 64-bit version is supposed to work on systems using legacy BIOS to boot their OS, but in my specific case, it didn’t. On a side note, perhaps you should use the 32-bit package strictly for older systems using legacy BIOS, to avoid installation and boot issues.

Install Overview

Quick info on how to install ROS, NOT dual-boot. Take note, I tested the latest build version 3.0.207 (as of August 22, 2017), and all worked fine using this guide.

Note: To avoid headaches, installation and boot issues on older systems using Legacy BIOS boot, use the 32-bit package.

1. Boot from Hiren’s Boot CD, then choose the Parted Magic.
2. Launch GParted and create a new Partition Table (will wipe the disk out), then create a new ext4 partition, using all available space. Save/Apply and Reboot.
3. Boot from Remix OS ISO, set boot flag to INSTALL=1

4. Installation

   • Choose your target drive (prepped in Step 2 above)
   • Choose “Do Not Format”.
   • Choose to “install Grub Boot Loader”.
   • Choose if you want to enable read/write for /system folder
   • Installation should now take place.
   • Reboot
   • Glowing Remix OS Boot Logo should appear. This should take a while, around 15-minutes in my single-drive setup.

5. First Boot and Setup

   • Welcome Screen
   • Select your language
   • User agreement
   • Wifi setup
   • Recommended App install
   • Activate Google Play™
   • Done!

The Step-by-step Procedure

Install Lion Os X From Usb

In case you no longer use CD/DVD Drives, then you must have 2 USB drives. One for Hiren’s BootCD (1GB at least) and another for Remix OS (at least 2GB).

1. Step 1: Boot from Hiren’s Boot CD, then choose the Parted Magic.

   You can use similar tools, but for this guide I’d be using Hiren’s Boot CD, because it has all the features I need, not only useful with this setup.

   Download, extract and burn the .iso file to a CD, or use Rufus to write the file to a USB Drive and boot from it.

   Note: Download link is at the bottom of Hiren’s Download page.

   I’ll be using Parted Magic, which is included in the live cd. It has GParted and Clonezilla with it. It is basically a Linux with Desktop environment, so you can use it with a graphical interface and also includes a terminal.

   So boot from the CD or USB, then choose “Parted Magic”.

2. Step 2: Launch GParted and create a new Partition Table (will wipe the disk out), then create a new ext4 partition, using all available space. Save/Apply and Reboot.

   In case you still have your old partitions, you can simply remove/delete all those by creating a new Partition Table. Set the type to msdosand it should wipe all the partitions out. I’ve tried and tested GPT but it didn’t work in my case (legacy BIOS boot).

   Then right-click on the gray unallocated area and choose to create a new EXT4 partition. See video.

   Once done, apply and save. Logout and shutdown your PC.

   Turn it on again and switch to the Remix ISO Installer, then follow below step.

3. Step 3: Boot from Remix OS ISO, set boot flag to INSTALL=1

   Once Grub Boot Menu shows up, press e while Resident Mode is high-lighted. This should enable you to edit the boot flags.

   Notice that SRC= DATA= CREATE_DATA_IMG=1 text?

   Change that to SRC= DATA= INSTALL=1 and hit ENTER key.

   Install wizard screen (with blue background) should appear, now follow next steps below.

4. Step 4: Installation – Choose options

   • Choose your target drive (prepped in Step 2 above), usually it’s sda1 – for single partition drive with no other disks attached.
   • Choose “Do Not Format”.
   • Choose to “install Grub Boot Loader” – don’t be misled by old tutorials and out-dated guides out there. Remix OS 3.0 perfectly installs Grub without issues, using the ISO method.

   • Choose if you want to enable read/write for /system folder – in my case I chose NOT to speed up the process.

     Hit ENTER key and installation should now take place.

   • Eject the ROS installer, then Reboot.

   • Glowing Remix OS Boot Logo with black background should appear. This should take a while, around 15-minutes in my single-drive setup.d. After this, it should take you to the welcome screen. You are nearly there!

5. Step 5: First Boot and Setup – finally, set the following:

   • Select your language
   • User agreement
   • WiFi setup
   • Recommended App install – you’ll get this screen when your system is connected to the Internet.
   • Activate Google Play™

   Done!

   Note: One more thing that you need to set. When you check on Settings >Storage & USB >Portable storage, you’ll notice a “Corrupted Disk Error”. This is probably a bug, since it showed up on my several test setups (VirtualBox, USB, Windows, Single-boot, EXT4/NTFS).

   Be Warned!!! – you should not take the Setup process because it will destroy your current instance. It will mess up your partition.

   What you should do is to turn-off the “auto mounting” feature, which is an experimental feature. Do do this, go to…

   Settings >Experimental Features >Enable disk partition mount

   …and switch it OFF! Then restart your system. The next time you check that menu, it would be gone.

   Screenshot – Remix OS Corrupted Disk Warning

   I think this method is not that difficult right? You could also try doing this on a VirtualBox. It’s more safe and quicker when just trying out the OS. Isn’t this a good idea?

   Well, sure! But you might ask… How do I install Remix OS on a VirtualBox? — It is much simpler than you might imagine, see details below.

Remix OS Virtual Box Installation

To install ROS on a Virtual Machine, you need VirtualBox or similar software, the ISO image and my favorite tool Hiren’s Boot CD. You could use your own tool. The general idea of this is to use a third-party partitioning tool to prep your hard disk drive.

If you read the hard disk single-boot method, then this guide would be easier for you to follow.

Procedures

1. Step 1: Create a new VM.

   Launch VirtualBox and click New, then fill out the following details:

   • Name
   • Type
   • Version
   • Memory Size
   • Hard disk

   If you would use the 64-bit version of Remix OS, then choose Other Linux (64-bit) from Version field.

   Minimum Memory Size should be 1024 MB, you could adjust as you wish, just make sure it’s not more than half of your total system RAM.

   Click Create, then proceed to step two below.

   Reference Image:

2. Step 2: Create the Virtual Hard Drive

   Depending on your free space, you could create any virtual hdd you would want. If you have a dedicated partition or hdd just for VirtualBox to use, then you might want to use the full space available, leaving a little space for buffer. In my case, I chose to use 32GB Dynamically allocatedVDI, because it’s quicker to make than with Fixed SizedVDI.

   Note: Fixed Sized VDI will allocate and consume your hdd space though the disk would still be empty. So if you will create a 16GB VDI, it will show as 16GB file when you check its properties. While for dynamically allocated hard drive would not. It’ll grow when you start putting file into the drive.

   Reference Image:

3. Step 3: Configure VirtualBox and attach the Remix ISO, then boot from it.

   Click on the newly created VM and hit ctrl + s to launch the settings window. You could also access the page by right-clicking and then Settings.

   Go to System >Processor tab and select Enable PAE/NX.

   Next, go to Accelration tab and make sure Enable VT-x/AMD-V is tick/enabled. Click OK to save.

   Reference Image:

   VirtualBox Settings for Remix OS

   Next, mount HBD ISO:

   Choose Storage, then click on the cd icon below your virtual drive, it should appear as empty. Then on the far right corner of the page, click on the drop-down with cd icon or with the label “optical drive”. Choose Hiren’s Boot CD and click OK. Now you’re ready to start the VM.

   Reference Image:

4. Step 4: Start the Remix VM and follow the single-boot method above.

Answers To Common Issues

• Why would I install on C: drive, would it not mess my Windows partition?

  Answer: No, it wouldn’t. Because Remix OS 3.0 would just copy the files on the C: drive inside a folder of it’s own. It will use a file called data.img as its Internal Storage. Treat it like a container for your files. For the newbies, that data.img file is your hdd when using Remix with Windows.

• Can I resize the data.img file larger than 32GB?

  Answer: Yes, of course. You need another tool for that, and you can use one for Windows or Linux. Guide on how you would increase the data.img size is not yet posted though. But I will soon write the guide for it.

• Why first time boot takes long?

  Answer: That’s pretty normal especially when using USB 2.0. It can be faster when using USB 3.0, or SSD Drives using Windows or Standalone Method. Another reason is because of data.img creation. I won’t discuss the details, but what’s actually happening behind that boot screen logo is… ROS is actually creating the file data.img, then formats it to a usable format (ext4), then lays out the necessary directories like; Photos, Documents and etc. Also, time it takes depends on your chosen system storage during the installation (8GB, 16GB, 32GB).

• Can I just copy the “data.img” file from someone or somewhere else?

  Answer: Yes you could. Just slap in the data.img file inside the Remix OS folder and boot up. Make sure you do this right after the installation, before you make a reboot. Though, this might lead to security issues – when you copied or downloaded it from the Internet. You won’t know that files might be included in that image.

• My PC hung up during the first boot, any solutions?

  Answer: If you follow the Windows method, the installation might have been incomplete. You need to login to Windows again, uninstall and reinstall. Make sure to watch the window for errors or notices. Make sure that that you have an unformatted_data.img file before you reboot. If this still fails, edit the boot flags under Resident Mode and set flags to DATA= SRC=/RemixOS CREATE_DATA_IMG=1, hit ENTER then b once you get back to the previous screen. It should boot ok and create the image file, which should take a while.

• I created a USB installer and used it to install Remix directly to my HDD – but grub won’t boot?

  Answer: I’ve tested this several times on different methods, the USB installer won’t install Grub perfectly. Using the ISO method works fine. Some old posts out there tells you to NOT install Grub and skip it, then install later, which will make life difficult for newbies. Well, in Remix OS 3.0 you don’t have to do that. Just use the ISO, it should work.

• I only have a single partition on my Windows machine, can I create a separate partition for Remix OS to use?

  Answer: Yes you can! Use any partitioning tools like GParted, it’s included in; the Hiren’s Boot CD, Linuxmint, Ubuntu Desktop Live CDs. You can use other tool like Easus Partition Manager. Gparted can be accessed via Once you made a new partition, format it to NTFS and mount it in Windows.

It’s a Wrap!

If you follow this guide very carefully, you should have installed Remix OS successfully. But if you ran through issues and got stuck with something, feel free to ask below and I’d be glad to answer when I have the time.

And if this guide worked for you, then pat yourself on the back. You have followed carefully. Please share to others too, okay?

One thing… I’ve gone through several old posts which are no longer relevant to Remix OS 3.0. So I wrote this tutorial (my first ever post in 2017) for future readers. Some guides out there only works with the old version, some points to v2.0 and beta versions of Remix. So if you came across one, you may point/link to this post.

The steps below will guide you through how to Install OS X Snow Leopard from a USB Flash Drive. Alternatively, you can also read these instructions on how to install OS X Lion from a USB Flash Drive.

Reinstall Mac Os X From Usb

Apple officially released Snow Leopard a couple years ago and consumers can still find the latest version of OS X at Apple Stores and resellers across the country.

Install Os X From Usb Drive

At version 10.6, Snow Leopard, focused more on improving speed and performance than adding new features to OS X. With the operating system available to customers, individuals are ready for their upgrades.

Installing OS X From a USB Drive

Like other versions of OS X, Snow Leopard can be installed from a USB drive. This is especially beneficial to Macbook Air users looking to install the OS without a DVD drive. To do this, you’ll need to prepare your USB drive with the installation files. Like many of our other Mac Help articles, the steps listed below worked particularly for Snow Leopard but should also work for installing OS X from USB on Leopard.

The installation files sit at 6.2gb on the Snow Leopard DVD, so you’ll probably need a drive that has at least 8gb available. If you want your installation files to last against the elements, check out this 8 GB Water/Shock Resistant USB flash drive.

Installing Os X El Capitan From Usb

After you’ve gotten the correct USB device, connect it to your Mac and prepare it with the Snow Leopard installation files by following these steps:

NOTE:Depending on your flash drive, you may need to follow steps 5 – 7 on installing onto a USB drive to make sure the drive is bootable before you get start. This includes updating the options for the partition so that it is set to a GUID partition. If the USB drive is not bootable you will NOT be able to install from it.

1. Open Disk Utility and select the Flash Drive
2. Select the Erase tab on the right and then set Format to Mac OS Extended (Journaled). Name the partition you’ll be creating Snow Leopard or OS X Install so you can keep track of your installation device. After you’ve done this, click the Erase button.
3. After Disk Utility finishes erasing your old data on the flash drive and setting it as a new partition, it will be ready for the Snow Leopard install files. Select the Restore tab at the top and then drag the Snow Leopard DVD to the Source field. Select your USB device for the Destination file. Click Restore and wait for the restoration to finish (about 20 minutes).
4. If the restoration worked correctly you should be able to open your USB device and see the Leopard installation files. If you try and click the Install OS X Snow Leopard icon, you’ll get the message below telling you you can’ install OS X from this volume. IGNORE the message. The next steps will walk you through the installation steps.
5. Now that the installation files are successfully on your USB device, be sure to remove the Snow Leopard installation DVD from your drive. Next, restart your Mac and when it first starts to reboot, be sure to hold down the option (alt) key on your keyboard. After a few seconds at least two volumes should appear for you to select from for installation. One of those will be the USB drive we just prepared. Select it.
6. After the Snow Leopard installation software boots from your USB drive, follow the on screen instructions for installation. It took about 38 minutes to install Snow Leopard on my machine from the USB drive. I’m curious to see how this compares to the average Mac users, please leave a post in the comments letting us know how long it took on your machine.
7. After the installation finishes, it will reboot your computer into your new upgraded version of OS X, version 10.6 Snow Leopard

This method works for installing OS X Snow Leopard onto a Mac from a USB Drive. It should also work for installing Leopard or other older versions of OS X on Intel Based Macs. Check back often for additional help and tips for your Mac.
