Configuring grub
am 12.09.2008 16:03:19 von Dermot PaikkosHi,
I have hit a problem. My HP server rebooted after installing some
updates and gave me a red screen Illegal OpCode error. After doing some
hunting around, the best answer I found was on a thread on a mailing
list that said that the error was due to the the BIOS trying to find a
correct boot image and failing.
I can boot the system from the OS CD (CentOS) and chroot so that my
existing root system is installed. What I can't seem to do is get grub
to re-install the boot loader into the MBR. In an effort to make it do
so I booted the server with a MS dos floppy and did fdisk /mbr. That has
remoced the red screen message but I still can't get grub to configure
my MBR correctly and I am left with a missing operating system message
from the server.
Here's what I've tried
>grub
grub>device (hd0) /dev/cciss/c0d0 # Compaq device names
grub>root (hd0,0)
grub>setup (hd0,0)
I get a number of messages
Checking if /boot/stage1 exists...(no)
Checking if /grub/state1 exists...(yes)
Checking if /grube2fs_stage1_5 exists...(yes)
Running embed /grub/e2fs_stage1_5 (hd0,0) failed (this is not fatal)
Running embed /grub/e2fs_stage1_5 (hd0,0) failed (this is not fatal)
Running install /grub/stage1 (hd,0) /grub/stage2 p /grub/grub.conf
succeeded
Done.
It always reads as if it's ended successfully but nothing changes and I
can't get the boot loader into the MBR.
Can anyone spot where I might be going wrong?
Thanx in advance,
Dp.
