Grub Duall Boot Problem

[James Black <blackman@xxxxxxxxxxxx>]

Having a Windows XP Installed and also wanted to boot in linux I found 
that this is a problem on FC4 r3 64bit when in fc3 works great... It 
seems that grub starts on basic command line, and if i try from rescue 
mode to : chroot /mnt/sysimage and then grub-install /dev/hda
1) Nothing Happens
2) sometimes it drives me to error 17 or error 15

It also seems to work great for grub-install /dev/fd0....

It looks like Something is really wrong with grub in this pre-release!
