question re: reinstalling grub loader

[jjj0923]

I have to re-install the grub loader on one of my systems

My Centos installation has 3 partitions
100 meg for /boot
6000 for swap
and the rest is created for /

my device names are:
/dev/cciss/c0d0p1 (boot)
/dev/cciss/c0d0p2 (swap)
and /dev/cciss/c0d0p3 ( / ) respectively.

I am not sure which partition (the boot ‘p1′ or the ‘/’ ‘p3′ should contain the grub loader. My /boot partition is marked as boot with an asterisk?

any help would be appreciated

It should be /dev/dciss/c0d0

Grub will be installed on the mbr, which is the first few sectors of the entire disk that hold the partition information as well.

so my command should be: "/sbin/grub-install /dev/cciss/c0d0" ???

just to confirm...

thanks in advance

I did this:

/sbin/grub-install /dev/cciss/c0d0

and now the system reboots and winds up at the 'grub >' prompt

what now?

there was no grub.conf created.

what next?

Was this system previously functioning, booting?
Did you have a grub.conf file, which would indicate Grub Legacy?
Do you have a Live CD you can use to mount the boot and/or root partitions to see what is there?
What is the output of fdisk -l command as root? (Lower case Letter L in the command)
