Windows 7 boot gone

[Diablo]

so i had Win7 RC as my main OS, then i got a second hard drive to put some file, all it had was some pics and videos, then i decided to pop in the XP cd and install it in the second drive, after the installation goes through i find that my Win7 is gone, it boots straight into XP and the OS options only shows XP. in MSconfig it only shows XP home edition, any way to recover my main OS?

thanks
