hmm.. can you post the contents of /media/etc/mtab, /media/etc/fstab,
/media/boot/grub/device.map and /media/boot/grub/menu.lst just to
see, if grub is really accessing /dev/sda5 (which would be "hd(0,4)"
for grub)... but to be honest, i don't understand what's going wrong,
too.. does the file /media/boot/grub/stage1 exist?
gotta go to bed, cya,
robert.
