I’ve got an external USB drive that’s a bootable clone of a Windows XP hard drive (theoretically — I haven’t confirmed that a PC can boot from it).
I’m trying to get my Intel Mac mini to boot from it. I’ve tried plugging in the drive, then holding down alt as I start the Mac, but it doesn’t show up in the list of bootable drives. (I’ve got a working Windows XP Boot Camp partition on the Mac mini’s internal drive, as well as the Mac partition).
This KB article suggests it may not be possible to boot the machine from it.
Anyone know a way to boot from the external USB drive?
