It should've mess with your specs. I know there is an issue in the order in which you install windows xp and windows 7 for dual boot, windows 7 should be fine. One thing to consider is your processor. I have the core I3 a 64 bit processor and it wouldn't let me install the 32 bit version of windows 7. If you proceed, yes install as regular just pick a new partition. Also once install goto msconfig.exe under the boot tab select your main os. That way when you reboot your pc the default will be on the top. This way you won't be confused upon reboot.
