Weird Problem after I installed another version of XP

I have a botched up install that I think is unfixable

I go ahead and try to reinstall it and everything is fine

here's my problem:

if I leave the CD in the tray it goes to my new install

if I take it out, it goes to the old install

there's now two partitions

I'd like to keep the files in my old install but I don't know how to dissolve it without losing all my files

the partitions are both drive C: and it'll only boot the new one if I keep the CD in there and I can't access files from each partition or I'd move them and then dissolve it

If I hit F8 it won't even give me the option of selecting the new one

I've never encountered a problem like this and any help would be appreciated

Go to the control panel, system, advanced, startup and recovery settings. Click on the drop down menu at the top where is says default operating system. How many versions are listed?

Do that when you boot without the CD and if there are 2, change it to the new version. You still should be able to view your old files by following the old path to your documents.

I just found out that I have two HDD in the computer

I'm going to mess with the master slave settings to see if I can fix this.

Fixed.

It was my dad's computer and I didn't realize he had two Hard Drives in there.

so, my bad.
