GRUB was dual booting RH Linux and Win 98.
I read it some where and did "fdisk/mbr" in Win98.
Now how can I restore GRUB without reinstalling Linux?

I dont have a bootable floppy disk.
I only have installation cds, version 7.2.
Please let me know installing GRUB again with my previous configuration.

You should be able to boot your Linux installation from the installation CD. The command line is probably something along the lines of rescue root=/whatever/your/root/device/is.

Once you have logged in you can run grub-install.

Installation CD booted in rescue mode and mounted the file system of my hda in /mnt/sysimage.
That means my hard disks' root ( / ) is mounted on /mnt/sysimage/.

I did the following:

$ /mnt/sysimage/sbin/grub/grub-install /dev/hda
as my original "/sbin/grub/" is now equal to /mnt/sysimage/sbin/grub.

But it gave an error message:
/sbin/grub: Not Found

I also tried

$ /mnt/sysimage/sbin/grub/grub-install /mnt/sysimage/dev/hda

But no use. Another error message ( I dont remember it, sorry)
I use RedHat Linux 7.2

Now please help me.

you will need to chroot to /mnt/sysimage

the command will be:

Then it should be able to find your /sbin/grub

What that command does is set /mnt/sysimage to be /

/sbin/grub-install ?
