I have purchased Win XP for my computer and i would like to make it my second OS on my computer. So i used partion magic to make a second partion on my harddrive. Now how do i install the second OS. I set the new partion active and then reboot. I place the Windows boot disk into the A drive and let the computer do the work, i get to a prompt that says:
1: Help
2. Start with CD support
3. Start without CD support

Where do i go from here. When i click start with CD support the A drive loads all of my cd driver info and then i am left at the A: prompt, what do i do next. How do i install DOS and then eventually XP. I tryed to switch to my CD drive and type Setup.exe, in hopes of XP going into setup but i got a message: Unable to perform this in DOS or somthing like that. How do i get out of this problem and install my second OS.

Thanks to all that help.
