Windows XP installation problem over Fedora 13 (existing) - Help!

[lilpirate]

UPDATE - I finally managed to install XP. But now, after getting back the GRUB, I am again getting the error - "A disk read error has occurred. Press Ctrl+Alt+Delete to restart" when tried to load XP from GRUB.
Is there any way I can get back the Windows Boot Loader menu and have Fedora in it?

Hello,

First of all, I'd like to tell you that I had installed Windows 7 (clean) on my new computer. Then, I installed Fedora 13 64-bit. Eventually, I wanted to install Windows XP, so, formatted the drive (NTFS) which had Windows 7. Now, I have Fedora 13 running good. But, now, when I'm trying to install Windows XP I'm getting different errors. At first, it was - "A disk read error has occurred. Press Ctrl+Alt+Delete to restart".

I took a MS-DOS 6 CD and booted up. Ran chkdsk, but it checked only my CD-Drive. Nothing else. When I tried to run fdisk and looked for existing paritions, it showed me nothing inspite of having 6 partitions on my 1TB HDD.

One of it is ext4 (Fedora), swap and others are FAT and NTFS.

Now, after running chkdsk, when I tried to install XP, I get an error - Error loading operating system.

I googled, and found this - http://www.computerhope.com/issues/ch000730.htm And I'm pretty sure that my issue is "Cause" (as on the page) #3, that is -

Issue with drive's partitions.

And it the solution is suggests is -

This issue can be cause if the disk drives are not properly setup or have been changed by another program, such as a utility that comes with a Linux distribution. To resolve this issue, delete and recreate all the partitions before running the Windows XP setup.

I don't want to delete and recreate all the partitions

I've well setup-ed Fedora installation. Does anybody know a solution?

What (as say Microsoft) "bad utility" you used ?
Can you boot Fedora ?
If yes, please, post the results of :

# fdisk -l
