If you're thinking of moving a hard drive with a version of Windows installed, stop. It will not work properly and you'll have to install a fresh copy of Windows to guarantee full functionality.
Yes this hard drive already has window xp installed and i would not mind installing a fresh copy of windows 7 onto this hard drive which i assume would wipe out everything on the hard drive as well. Should i just place the hard drive in, make sure the mobo boots on the hard drive and insert the windows 7 installation disk?
