This is the genuine disk. such as the following

with the appropriate windows sticker with the 25 number and letter key
Not the exact disk i have, i just googled and found a image. dont want to go host a photo somewhere at the moment
seccondly, most of the time, the install does not even get to that point, it usually stalls out and crashes before that, either after the "loading files" and at the "starting windows" of the disk, or shortly after i start the install or partitioning if i started out with unpartitioned drive
I could use a vista restore disk that came with this computer, but i am NOT a fan of vista. the thing just would'nt stop crashing on me, that instable OS. Originally the reason i went to linux.
also have one of these, but the purple one for xp home (not the restore disk for the computer, just a random one), and i have a vista one too. Instead, its brown and SP1 that came with this computer
