Thanks for the reply. I have tried reinstalling maverick using that method, but the installer does not start. I either get a black screen or a blinking cursor at the top left.
I can occasionally get squeeze to run from an SD, but it will only boot 25% of the time.
I'm not sure how boot order works on the efika, but could it have to do with that?
Just a shot in the dark here (I've never run into this one myself) but. If you can boot squeeze from a SD card 25% of the time then I would try booting squeeze and zeroing out /dev/sda using something like dd if=/dev/zero of=/dev/sda bs=1M You shouldn't have to zero the entire disk, just enough to blow away any partition/filesystem info.
Then I would try booting the maverick installer SD card again and see if that solves your problem.
(This is all assuming that the contents of the SSD are somehow the problem and not something else)
