Not sure you can.
I think you have to have Windows running for the OS to recognize a USB
drive. Â I suppose that's possible with Windows Setup.
I'm pretty sure though, for that to work at all, your BIOS will have to
recognize a USB drive FIRST; so it knows to boot from it.
So, if your BIOS doesn't offer "USB" as a boot option (and I cannot
remember one that does; SATA, CD-ROM, Floppy, SCSI, and IDE being the
"normal" set of bootable options), then you probably cannot boot;
therefore you'd have to have some other drive as boot-drive.
It *might* be possible to set up a CD-ROM or Floppy as the boot-drive,
that would then switch over to the USB drive, once the USB driver was
loaded; but I'm not sure how that would be accomplished.

Hmmm ... Seems I'm wrong. Â More "modern" computer motherboards than mine
*do* seem to be capable of booting from a USB drive.

However, you have to make damned sure the motherboard you have or have
in mind to buy actually *has* that capability.
If not, then to make it work you'd have to get another or different
motherboard.
