My Google fu has failed me, so I turn to you dear reader.
What I wish to do is to boot a Linux distribution that is installed on a USB-harddrive, just like on any other harddrive. The only issue is that I have encountered many BIOS's that either does not detect or as in one case, an Acer laptop, where the BIOS freezes completely once the drive is plugged in.
Tough every BIOS has been able to boot a LiveCD. So I shoved the ArchLive CD into a couple of computers, trying to use GRUB to boot to the USB-drive. But failed miserably, the only drives detected were the CD and the local harddrive.
So I'm asking you for a foolproof way to boot to a USB from a CD. I want a CD which only purpose in life is to push on to the USB.
