CentOS on USB... GRUB Hard Disk Error


I installed CentOS 5.7 on an USB stick today using netinstall from another USB stick. Installation worked fine and was successful.

But when I try to boot from it I just get "GRUB Hard Disk Error" and nothing else.

Boot priority is correct and I put GRUB on the correct drive during installation.

Anyone with a clue? I dont want to buy a hdd right now considering the prices.

I read somewhere that updating the BIOS could solve it. Found this guide that seemed useful.
Unfortunately the newest version of Ultimate Boot CD doesn't have "afudos" which is used in the guide. Found the version he's using (4.1.1) but that one is not supported by the current version of "Universial USB Installer" from pendrivelinux -_-

It might be helpful if you show the complete Grub hard disk error, as well as part of /boot/grub/grub.cfg (from the beginning of the file down to include the first menuentry stanza).


centos, grub, usb drive
