My C: became my D: HELP!

As the topic title says I need help here.

Here's what happened:

Before I repair install my OS (Windows XP) my HD C: and D: are ok.
Until I Repair my OS (for some software reason). My C: become my D: vice versa.

This means that WINDOWS can be located in my D: which is bad because some of my softwares are installed in my C: some in my D:

So I'm wondering how can I take it back to its original state?

For Hardware Facts my C: is 20gb and my D: is 30gb. (before repair)
C: 30gb D: 20 (after repair)

So I'm wondering what should I do? :confused

 

So what 'repair' did you do and why?

 

I'm not sure if it was a repair or reformat but as I remember it says that My Documents and other files will be deleted. So I back-up in my Original D:.

I repair install my system because Flyff won't work anymore, it keeps on restarting everytime I start to play the game. After the installation it worked perfectly.

Btw how to change my Master HD and Primary HD? Since my Motherboard has only one wire that connects both HD C: and D:.:zzz

And I forgot to mention that my D: (30gb) is my Master HD.

 

When you boot computer, and motherboard settings are being loaded on the Dos screen .. Black with white writing do you see it halt for a few seconds and see 2 XP's there asking you which one you want to use. If you have loaded another XP on ''D'' the ''C'' XP should be there as well. Best thing is go through the install procedure again using your XP disc and follow on-screen instructions to install, when it comes to the Blue scren asking you where to load it C or D check how much free space left on 20 Gig. This should tell you if you have formatted it.

 

Ok to make all things clear, I'll summarize.

Before I reformat my system my C: which is 20gb is my Program HD contains Windows Files and Programs Files.
My D: which is my second HD is for downloading purpose only.

The things that complicates all is that my D: is my Master IDE and making C: my Primary. I just don't know how my C: ended up to be C:. Get it?

So after the install I ended up my C: > D: and D: > C.
Which means my computer boot from D: not from my C:

Major conflict is that when I install some programs in my system, it directly install in my C: some of them are in D:

Just a thought, is it possible to interchange my C: into D:?
By changing their IDE Cable and Jumper Settings?
After doing it, it will change directly? No needing of formatting?

Thanks.
