How to unistall grub

hai,
i have a problem. i installed RHEL 4. The system got hanged during installation.so now i want to install Windows XP. when i boot from cd i am getting grub> prompt. so i want to remove grub from MBR.
And i am having 128MB RAM.whether it is recommended for installation for RHEL4.

Give me a solution for removing grub

Thanks in advance for any help

fdisk /mbr

from DOS

or

fixmbr

from Windows Recovery Console

I've used this to remove lilo, which should also work for grub

dd if=/dev/zero of=/dev/hda bs=446 count=1

The thing placed after

fdisk /mbr

or

fixmbr

will exec. bootsector of the active partition and this will do nothing: so anyway you will not can install WinXP after that because NT-installer puts partition bootsector, but does not rewrite MBR.

Those are Chinese glyphs. On my PC at least. He must have cut & pasted something from his own PC. I don't think he's using cyberchat at all.

I believe that the use of Chinese logograms represent a violation of the final sentence of rule 9. We have previously disallowed posts in German, Spanish, French and Portuguese.
