Boot Usb From Mac
Boot Camp Assistant User Guide
You can use Boot Camp Assistant to install Windows 10 on your Intel-based Mac.
Once BootCamp creates the partition and starts to load the Windows 7 or 8 Installer, power off the Mac by holding the power button for ten seconds. Boot the Mac while holding option key then eject the disk. Power off the Mac again. Insert your Windows 10 USB Installer and Power on the Mac. It will start up in Windows 10 Installer. This Mac OS 9.2.2 'boot kit' was made by @that-ben and makes the process of booting (and installing) Mac OS 9 on any G3 and most G4's from an USB stick a little bit easier, because not all the Mac OS 9 install CD images can be used to boot a Mac from an unlocked volume (such as from an USB stick or hard drive).
Install Windows on your Mac
Depending on the model of your Mac, you might need an external USB drive to install Windows (you’re asked for one when you prepare your Mac for Windows if it’s required). Newer Mac models—with OS X 10.11 or later—use the internal drive to temporarily store the items you need to install Windows and don’t require a USB drive. To find out whether you need an external USB drive, see the “Learn more” section in the Apple Support article Install Windows 10 on your Mac with Boot Camp Assistant.
To install Windows on your Mac, do one of the following:
If your Mac doesn’t require an external USB drive: Follow the instructions in Install Windows on your newer Mac using Boot Camp.
If your Mac requires an external USB drive: Follow the instructions in Install Windows on your older Mac using Boot Camp.
Set the default operating system
After installing Windows, you can set the default operating system to either macOS or Windows. The default operating system is the one you want to use when you turn on or restart your Mac.
In macOS, choose Apple menu > System Preferences, then click Startup Disk.
Click the lock , type an administrator name and password, then click Unlock.
Select the startup disk that has the default operating system you want to use.
If you want to start up using the default operating system now, click Restart.
