Make your hard drive the Primary Master, and the CD drives the secondary master.
Your hard drive should always be on the primary IDE drive (Primary Master).
Do you have any data that needs to be saved?
If not, I would reformat and reinstall. The reason being you have too much going on, on your computer. Too much wasted space.
Will it boot to CD?
If so, pop in your XP Home or Pro disc (Whatever the COA- Certificate of Authenticity- is on the side or bottom or top of the computer), and boot it up.
Press any key to boot from the CD....
It will load the files, choose install.
It will get to a point where it will search for previous versions of Windows.
If you have your data backed up- or you do not need what's on the computer
follow the prompts to delete the partition- each one, one by one.
You should end up with a full, unpartitioned drive, ready to format.
Choose format (not quick)
It will take a while.
Then you start loading Windows- from there you will have to enter the COA,
install all the drivers, and you should be up and going after a couple of hours.
When you have that many different versions of Windows on different hard drives and things- your asking your computer to mess with you
