I had the same exact problem... as do/did many others. Google that error and you'll see...

What I found suggested was to make sure your DVD ROM is hooked to the first/0 controller. That did not help me.

What did help, as suggested by someone, was to replace my DVD ROM with another drive. I happen to have DVD ROM reader lying around... and that worked!

I was using a DVD Writer... maybe that was the problem?
