Hello, I just installed win 8 (from win 7) on my HP dv7 1253ca laptop it worked very well until Microsoft made some updates. The next time I booted the laptop I got the "
win 8 welcome screen" and then connection and deconnection and it goes, it seems to me, into the sleeping mode with the screen showing the day and the time of day. Now I tried to reinstall the system with my "Win 8 dvd and my cd player won't read the dvd, so I tried to go into the BIOS and nothing happens. I'm stucked.

If, for instance, I change my hard disk, will I be able to install another system like win 7. My original set-up was Vista (I tried to put back the original Vista but my CD won't read it also. So It seems I have two unsolvable problems.
