HI all,

I had centos on a laptop (dual boot xp).
I am giving the laptop to another person so I removed centos.
Now when I reboot grub is confused...

I tried to manually enter
rootnoverify (hd0,0)
chainloader +1

This does boot into XP but how do I tell grub that this is the new rules and
do this everytime at boot.
