Dumping on PC

Okey, so I am trying to dump a .iso from a PS3 disc. The problem is that my computer/drive won't read the disc. The thing is back when I had windows 7 it worked, now it just doesn't wants to. Any tips on what I could do to fix this?

For the record, the drive I have is called: hp BDDVDRW CH28
