I've searched on "How To's" to do this.  However, all of them (example) are like this:

http://pcsupport.about.com/od/operatingsystems/ss/instxprepair1_5.htm

I get to STEP 5 (in the above example), but the NEXT screen/page is different than mine.  What I get is a screen that shows 3 partitions on my HD:

-: Partition 1 [FAT]         71 MB (62 free)
C: Partition 2 [NTFS]       71336 MB (25802 free)
E: Partition 3 [FATS32]    4910 MB (452 free)

Might sound stupid, but which one is my XP os on, and/or which one should I select?  I can tell you that I went as far as the next step by selecting drive C, (as that's the one I presume I'm attempting to repair).  But again,....EVEN the next screen I get is different from the screen on STEP 7 of the example above.

Any help is appreciated.  Thank you.

Just a note.......I WANT to do a repair of XP, not a clean/new install.  I see that there's an option at the begining to press "R" to repair, but all of the instuctional websites I saw said NOT to choose the "R" option.Oops.  Sorry mod(s).  Just realized I posted this thread in the wrong forum.  Please feel free to MOVE if need be.C is the drive you want.
Try this repair and see if it gets you through.
