I'm trying to install windows7 on a new HDD but my dvd drive wont recognize my brand new win7 disc. It does however read anything else you put in it. Driver is up to date, also will not boot from the dvd drive. it tries, then skips to the HDD. Old HDD still works, fyi. Im trying to replace it before it crashes on me. I have also tried the disc in a different computer and it will load, so the win7 disc is not faulty.
