I cannot get past the restore screen

So, big problem. I have had to replace my logic board. Following this, using Mountain Lion, my mac was unusable, just beach ball on every click. I did restore Mountain Lion, but no change. I cannot restore from time machine as I get an error message saying restart. Now, I cannot get past the restore screen, no matter what keys are held at startup. If I hold the option key at startup, I get the recovery disk and back up showing, neither of which can be used.

In short, I'm stuck, any help appreciated!
