GRUB just plain won't boot by itself
I've messed up the MBR of a video surveliance device. I've installed GRUB in the MBR and now I get a GRUB> prompt when the PC starts, I can then get it to boot by typeing in
root (hd0,0) setup (hd0) configfile (hd0,0)/boot/grub/grub.conf I guess it's not seeing hte config file and whe it does it'll kick off and boot right up, I figred this command using the Super Grub Disk. I've also booted to knoppix LiveCD and done what's suggested in another thread which is to boot to a liveCD, and run grub with these commands To install grub: grub opens the grub shell root (hd0,0) tells grub that the /boot directory is on drive 1, setup (hd0) puts grub on the mbr with no luck Any help or suggestions would be greatly appreciated, I've tried just about every GRUB command but the right one I think |
What distro are you using?

well it depends on whether /boot partition or sub-folder to / is truly on first partition.
2) use that live cd again to run a partition tool to see what your structures are. 3) I prefer su grub root (hdx,y) setup (hd0) quit using a live cd...where hdx,y is the partition that truly contains /boot. 4) when you boot that live cd can you post the output of fdisk /dev/hda fddisk /dev/sda just in case we do not have a true linux structure 5) alternatively ....you can follow my troubleshooter to see what partitions are etc 6) I prefer not to use a config file and we have not seen your error messages to know if you have one. the live cd...can list the contents of hda1 or sda1 /boot/grub/menu.lst Knoppix has icons on the desktop that can be mounted read only when you click on them |
