Hi,

I have got Toshiba satellite note-book.
Now it had stopped booting becuase of some power disruption.
I am getting
"grub>"
and not booting the kernel.

on pressing tab it is showing some commands.
I am helpless.

System is Fedora-Red Hat
Kernel version probably: 2.4.2

Please help

I did that already.
But no command in that post is working for me as there are only some particular commands are available.

Possible commands are:

background blocklist boot cat chainloader clear cmp color configfile
debug displayapm displaymem embed find foreground fstest
geometry halt help hide impsprobe initrd install iorobe kernel lock
makeactive map md5 crypt module modulenounzip pager partnew
parttype password pause read reboot root rootnoverify savedefault
serial setkey setup splashimage terminal terminfo testload testvbe
unhide uppermem vbeprobe

What you have to do is boot from "linux installation CD" then at boot prompt type

Code: [Select]

linux rescue
Then it will search for previous installation and if it founds it.. (it will find if your system is not under serious problem) then will ask to mount and under /mnt/sysimage . . Say yes

Then type

Code: [Select]

chroot /mnt/sysimage
then type

Code: [Select]

grub-install /dev/hda
PS: I have not done that from long time ... i am sure all is given in order but do use your common sense when you do at ur place.. it is easy to follow there..
