installing via unibeast, get "still waiting for root device"

Uh oh, now I'm at the 'choose language' menu and both the keyboard and mousepad aren't working, please PM me if you now a solution

Phew!! Ok, I was able to continue by plugging in a USB mouse and luckily the next steps didn't require any key strokes, was able to accomplish installation with mouse clicks. Looks like I'll be using Mulitbeast pretty heavily.

The ProBook has both, so not a concern for you.

FYI, I had the same set up where I only had 3.0, see my solution above but basically I was able to downgrade both to 2.0 through the BIOS settings.
