Hello,

One of my frend had a problem.
He had Windows XP installed on his system. Then he installed Red Hat Linux 8.0 in one of the partitions. After some time his XP got corrupt and then he reinstalled Windows XP. This over wrote the Grub loader entry, and due to this the grub loader is not displayed during the boot sequence althought the Linux installation is still intact.

One solution which i thought is that if he could get a boot disk, and boot through it and then make changes in the grub.conf file, though i have never tried this before. The problem is that here noone has a Red Lunx 8.0 boot disk.

Can anybody give a solution??

Thanks,
Rahul.

You dont need a Redhat Bootdisk, but if you would like one, you might be able to find the correct imgs for creating one, on Planetmirror.
You can use any LiveCD OS, such as SLAX, RescueCD. To recover your system. Boot the LiveCD, then once running,
cd /
mkdir TEST

Now mount the root Redhat (partition) system under Test, create any additional directories or mount the other necessary partitions underneath, example:
mount /dev/hda1 /TEST

Then change the current ROOT directory to the newly mounted dir.
chroot TEST

Since your now running on the RedHat system you should be able to navigate to where you need to go to reinstall the bootloader, run whatever it is to force a rewrite of the boot record.

If you still have the RH 8.0 media just insert CD1. When you get the 'boot' prompt type 'linux rescue'. Follow the prompts and it should locate your RH image. You will have to figure out what your boot device is at that point (like hd0, hd1, etc) and run 'grub-install'. Do a quick lookup on google and you will find plenty of info on grub-install.
