read first page. the only way he can recover from that "forced relettering of a system drive" disaster is to reimage, but he wants to solve the problem which will still exists: how to get the C: letter off of the 100mb system partition and onto his XP.
I believe the solution is to delete the 100 mb partition as shown above to free up the C: letter and then see how XP letters the drives. You will have C: available for a reinstall of XP in the worst case. Then use EasyBCD from XP desktop to add Win7 to bootloader because Win7 startup repair might otherwise re-write the 100mb partition.
A little more help here?
I can't use xp so I can't post a screenshot.
I followed this Microsoft KB that broke xp.

How to restore the system/boot drive letter in Windows
If you can successfully boot into 7 and XP, what is the difference... is this a performance issue, or just an annoyance??
That's the same one I followed that broke my Vista or Win7 awhile back. Didn't heed the warning at the beginning not to do it unless the drive letters have changed from one letter to another recently.
If you installed WIn7 second to XP, which I assume you did since it added the boot partition, then XP has proven its ability to change drive letters by lettering that 100mb partition C: after it was installed. Wasn't XP lettered C: before you installed Win7?
This means that XP can change its letter and may do so again if/when you delete that 100mb partition and reinstall the boot loader in XP as SIW2 suggests:
It's worth a try if you are up for it, see where the letters end up and go from there. . You'll need to reimage first, but that's easy with Win7 backup imaging. After we see where the letters land, it may need an XP reinstall but we need to see first. You can always re-image if you give up. But there is probably a fix in here somewhere since XP has apparently already shown that it can change letters after install, right?
