Of course, the BIOS needs to allow you to select the device if you are to boot from it, but what Windows itself says does not really matter.-Dirhael (January 15, 2009, 08:11 PM)
Bingo! You are absolutely correct. I should have stopped after my first sentence:
You can only boot to a device your BIOS supports and identifies as bootable. AFAIK there isn't any way to get around that.
In my eagerness to give an example with Win7, I screwed up royally.
Thanks for catching my error.

You could probably install grub/whatever on a floppy or MBR, and use that to boot from external media, though?-f0dder (January 15, 2009, 07:42 PM)
Yes. And traditionally, that's the way it used to be done.
But a floppy is a BIOS bootable device, as is the MBR. So you're really not booting off the USB if the initial bootloader is someplace else right? Isn't that more like a workaround?
Still, it does work, so I guess that's one way of "booting" Win7 from a USB key without really booting from it.
