I have always assumed the Windows Support Software, supplied by Apple for my Mac, was designed only for the legacy BIOS boot method of installation. Apple did not officially start supporting this method of booting Windows until after the 2011 model year.

The following Mac models support 64-bit versions of Windows 10 when installed using Boot Camp. The exact list of supported Mac models is given below. Staring in 2015 Apple starting omitting BIOS code from the firmware which ended the ability to BIOS boot from any type of drive.Īpple does not support Boot Camp Assistant installations of Windows 10 on 2011 and earlier iMac models. No Mac models older that 2011 can BIOS boot from an USB drive.

The only 2011 Macs which can BIOS boot from an USB drive are the MacBook Air and Mac mini models. User fdmillion's answer requires a Mac that can BIOS boot from an USB drive. Note the following regarding fdmillion's answer to this question
