I've been using Ubuntu 14.04 for a few months now and thought I'd update to a later version. Therefore, I followed this query (Update Ubuntu 14.04 to 15.04) and upgraded. Oddly enough, when I checked my version in the terminal, it said 16.04... So I'd upgraded to the developer version, instead. Restarted my computer, as per the steps. However, this appears every time on boot, and I cannot progress:

"end Kernal panic - not syncing: Attempted to kill init!"
I've already looked around for tips how to fix this. Started in safe mode, but I get the same error. I'd rather not reinstall the OS again, as I'd lose many of the preferences of programs I've installed before (Backed up the actual documents etc).
Any ideas?
