The fix is simple. Find a Windows98 Boot Disk with FDisk on it. Then use FDISK /MBR to re-write the boot sector. XP will work fine now. You may also be able to boot to the XP recovery console and use FIXBOOT or FIXMBR to cure it, but I have not tried that method. I have used the WIN98 Boot Disk method. I had the issue when upgrading an 80G HD to 300G. I found the fix searching the internet.
