Hi shooterd and Welcome to TSF,
First try to decompress the drive
1. Insert your installation DVD.
2.. Choose "Repair your computer"
3. Select your OS > Click "LOAD DRIVERS".
4. In the new box > Press Yes.
5. Navigate to your operating system drive > right click > Properties > Advanced tab.
6. Uncheck the "Compress this drive" option.
The above didn't work
Insert installation DVD.
Choose "Install now" > "Custom install".
Mark an existing partition > Install Windows.
Windows will then install another version of itself, and store all your other data in C:\Windows.old\, so that you can restore them at a later time.
If you have very important files, you could also detach the HDD from your PC, and insert it to another PC and extract your files first. Then do as above. You can then remove any partitions you like and structure the system the way you want it.
If you're using two operating systems, dual booting one XP and one Windows 7 for instance, you can boot into that system and repair the boot record from there. From your post I dont see you having this, but if you do, let me know and i'll tell you how to perform that action aswell.
With kind regards,
