Grub is corrupted

Hi,

Please help. I have a PC with three partitions: C, D, E. The C: and D: partitions are NTFS, and C: has Windows XP on it. D: holds my data files and folders in the Windows environment. E: has CentOS version 5.x. The machine is dual bootable. When booting up Grub gave me the options to boot to CentOS (by default) or to boot into Win XP (by selecting it).

Recently I used Partition Magic to resize the D: partition. I shrank the D: partition. The freed space space was then used to create a new NTFS partition.

After the partitioning was completed, I rebooted the machine. But now Grub is having a problem. It does not display the list of of bootable OS options any more. Instead there is just a black screen with the prompt:

grub>

What am I supposed to do here?

I am afraid that after I ran Partition Magic somehow Grub is messed up. How do I recover the previous boot options? Or at the minimum, how do I make the the machine to boot into Windows XP? Thanks for your help.
 
GRUB is not corrupted, but does not know where it's files are located at, by adding a 4th partition, where the 3rd partition was located...

reinstalling GRUB should fix that issue...
