Hi Laura

I'd try the safe boot first, as others have mentioned using the shift key. It 
should then start up and hopefully look "normal". After that, restart it again 
as normal and see how it goes. 
Then try the disk utility method off disk as mentioned by Ronni. 

Another thing you can try is shutting it down (force shut down via power key if 
need be) then unplug everything and take the battery out for about 15minutes. 
This can also help reset it as well. 

If still no joy and boots up with iCal taking over still, then let it start up 
and force quit iCal once it's booted. That should hopefully give you access 
back to the whole computer. You could then temporarily turn off iCal on startup 
from System preferences til later. 

Hopefully something there will get it working for you though.
And, yes, sounds like the MacMini came in handy :) 

Kind regards
