Cant boot Windows XP after installing FC6

[Erik Grootjans]

HI,

After installing FC6 I cannot boot Windows XP.
(Fedora 6 boots OK)
Booting XP I get the grub commands
 rootnoverify (hd0,1)
 chainloader +1
on screen and a black screen and thats it.

How can i get Windows XP to get booted by grub again?

Thanks

Erik

The file grub.conf seems to be ok.

uitput fdisk option p:

 fdisk /dev/hda

The number of cylinders for this disk is set to 14593.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)
