HP pavilion 8130
XP Pro
avg free-spybot S&D-adaware
2 new hard drives WD scorpio 120gb EIDE

OK, I installed both hard drives, and got the xp onto the C drive, and got up and running. Everything works fine.
I then attempted to format the second or "D" drive. When I put the disc in it started set up. I didn't see any choice of where.
At the end of the set up it asked if I wanted to repair or install windows or quit. It only listed the C drive, so I hit esc and popped out the disc.
The computer restarted, and now it wants to know which operating system to start.
1. Windows XP
2. Windows set up.

I don't understand how to make it format the D drive without affecting the C drive.
Also, now how to get the start up back to normal.
Can someone help?
