Subject: Re: boot from cd, point to thumb drive
I know how to use multisystem, but the computer I have now won't boot
from a usb stick.  I need to make a boot cd that will tell the system to
look to the usb stick.  If grub could be put on a bootable cd, I'd need
to be able to tell it to load whatever grub setup is on the usb stick.
