[K12OSN] Booting Problems

[ben may]

Hi,
after having a power cut, i realised that my UPS was not working, now at
boot my server says 'Kernel Panic: No Init found try passing init= option '
after google-ing that there were a few people that have had the same
problem. but no answers.

I have alot of data that i dont want to loose so re-installing is my last
option, or can i just reinstall with out loosing data in /home dir?
Thanks
