One solution is to replace the main disk drive with another one.  Install
a Ubuntu on the new disk drive.  You then put the removed disk drive in
an external USB hard drive enclosure and connect it to the computer.
You then should be able to access the drive that way.

Of course, if the hard drive is kapuuk you will have to get special service
to rescue your data.
