Can you please try new mr7.2.1 install CD:

We have updated Grml image we are based on where several EFI fixes
were applied. It works well on our side.

Unfortunately the old Install CD was worked well tool on our hardware
and test in VirtualBox.

Please share your new test results here.

Thank you!
