That's pretty old - and a little "flakey".
If you have a Windows install CD (win2k or later), try getting into recovery console and run fixboot.
You may be lucky - some are.
Else a re-install may be in order.

yes that what I do since there no command sys in the recovery console in the XP disc.

This is confusing:
OP says grub installed on Windows Partition---fixmbr will not fix that.

So where WAS GRUB installed? mbr or the boot sector of the Windows partition? (For the OP: How did you install GRUB?)

Nobody mentioned fixmbr - prior to you anyway.

OOPS!!!
I saw "fixboot" and thought it was "fixmbr".

How are they different??

Fixmbr does the MBR. Seems to do some basic checking; insists a primary partition is marked bootable and has ntldr in it.
Fixboot rebuilds the boot sector record within the partition itself. Seems to be less robust - sometimes it solves the problem of an overlay, sometimes (mostly ??) not.
I'd guess the success or otherwise is related to how many sectors actually got overlaid, but I've not done any testing to verify this.

I love it when I come to LQ and wind up learning more about Windows....

or

fdisk /mbr by booting with 9x/ME bootable disk.
