Error Loading Operating system

Please help me out

Make sure your BIOS boot priority is set to boot from your ROM drive.
Was there other OS running or its fresh machine?

Hi,

I just installed Redhat Linux AS4, after installation upon rebooting it is giving an error,
GRUB: Hard disk error.

How i can fix this issue, please help me out.

Regards

Might be useful to post the output of the "fdisk -l" command to show your partition information. Do you have the installation disk or a Live CD you can use to log in as root and run the command?

In order to get better idea of what might be causing the Grub error, how about downloading the Boot Info Script to the desktop of a Live CD, and then do the following as root user, but replace <username> with your username:
That will create a "RESULTS.txt" file in the same directory from where the script is run, namely your desktop; please copy/paste the contents of that file to your next post. That will help clarify your setup and hopefully what your problem might be.

I had a similar problem. Found Super Grub (search for "Super Grub") & downloaded a free version. Set my BIOS to boot from the CD, inserted the CD, booted up, followed the prompts until I was going in a circle, removed the CD, shut down the computer, booted up the computer, & it's worked perfectly every time. Proceed at your own risk. I was re-installing Ubuntu server and always coming up with the "stage 1.5" error, and it wouldn't let me boot. I thought it was a problem with the installation, so I tried it again. After the 3rd install yielded the same results, I went searching for something to fix a "Grub boot error" & found the Super Grub boot disk. It did a wonderful job for me. I THOUGHT I had saved a link, but didn't. However, if you search for "Super Grub" you should be able to find it.

Hope this helps.

How old is the Hardware that you have installed the OS on, and how big is the Harddrive? If you did not specify a small (<100MB) /boot partition when installing Redhat, and your HD is sufficiently large then that can cause a grub error with old hardware.

dear usr,

This is becouse you are installing the grub in somewere else rather than the mbr of the harddisk..Install the grub in MBR this problem will get solved..

I booted through Linux rescue and

df command is showing following details:
/dev/cciss/c0d0p1 /boot 698MB
/dev/cciss/c0d0p2 / 10Gb
/dev/cciss/c0d0p3 swap 10Gb
/dev/cciss/c0d1p1 /stage 68Gb
/dev/sdc1 /oradb 104Gb

What id did till now:
choroot /mnt/sysimage

grub-install /dev/cciss/c0d0

installation finished. no errors reported.
this is the contents of the device map /boot/grub/device.map check if this is correct or not, if any of the lines is inncorrect, fix it and re-run the script grub-install.
(fd0) /dev/fd0
(hd3) /dev/cciss/c0d0

Now what should i do, i am on the same stage GRUB harddisk error.
Please advise further

the output of this command
grub-install --root-directory=/boot /dev/cciss/c0d0


(fd0) /dev/fd0
(hd0) /dev/sda
(hd1) /dev/sdb
(hd2) /dev/cciss/c0d0
(hd3) /dev/cciss/c0d1
