Just in case, you may want to try this: # grub <--Also use --no-floppy if it hangs probing a floppy drive that doesn't exist--> grub> root (hd2,0) <--If your /boot drive is e.g. in /dev/hdd1)--> grub> setup (hd0) <--This will re-install GRUB in the MBR of /dev/hda--> grub> quit If this does not help then I am not sure what else might fix it. -- Regards, Mick
