How to resque and save files from a VirtualBox with Knoppix?

[Rikhard]

You made the right assumptions.
The vdi-file is in /home/rikhard/virtual boxVMs/windows7 where I also created a folder for communication between Mint and windows.
This is the first time I use VirtualBox, a sort of experiment.

But you gave me good hints how to proceed. So, I can use Knoppix after all.

But I have not the faintest idea how to create a virtual machine that will boot from CD. This is of course not the right forum for those questions, but if you or some one else has a link please post it.

thanks

Then how on earth did you manage to install Windows 7 in the first place ?
