grub> cat (hd0,0)/boot/grub/menu.lst where (hd0,0) represents (drive#,partition#) with numbering starting at zero and pointing to the partition holding menu.lst which should be your separate boot partition assuming grub was installed there originally and not to the root partition. (hd0,0) would point to the 1st partition on the 1st drive. (hd1,3) would point to the 4th partition on the second drive, etc... grub> geometry (hdx) will show existing partitions(x=0,1,2 etc.) . Can you boot from the grub prompt manually? ie. grub> root (hdx,x) grub> kernel /vmlinuz root=/dev/hdx <other options> grub> initrd /initrd grub> boot with appropriate modifications if you altered the default installation image names. where x points to appropriate partition. Note that unlike (hdx,x)mentioned above, root=/dev/hdx, numbering starts at 1 and points to root partition, not the boot partition. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
