critical problem using grub-install through linux

[mandy nagesh saraf]

Dear Sir

I am using RedHat linux 9 on a 40 GB HDD. The 1st partiotion contains windows 
98 and the linux is installed in the last 6 GB space.

I am using a boot loader called XOSL (eXtended Operating System Loader) to boot 
Win 98 or Linux. For that I had to install GRUB on the linux partition. 
Everything worked fine.

Recently I tried to install GRUB on the first partition using the command 
"grub-install /dev/hdo" from linux. After rebooting I found my HDD to be 
unbootable, even "fdisk /MBR" could not help. So I had to reformat my C 
partition and load windows again; and XOSL now worked fine.

I retried using the same command and had the same problem again.

Please look into the matter there may be some problem in how the command works.

If any more details are required pls mail me.

Thank you
