10.04 recovery mode problem with the keys

[Uwe Brauer]

Hello

I just wanted to repair a problem in my old Kubuntu 10.04
version.
I selected recovery mode and after a while a screen popped
up, offering 
regular
failsave
netroot
root

And may be others. However I could not move the cursor in
order to make my choice (I wanted root). The arrow keys did
not work, nor crt n or something like this.

I tried it on a Laptop and a regular desktop.

What can I do?

Thanks
