re-install

[Grizzly]

Hi All

First question here, I have made a 14.4 duel boot (Win 7) system, but during 
an 
overnight update "something" went wrong and even after going thru the repair 
option I still get endless "a system problem occurred... Report?" so my 
question can I install 14.4.1 LTS over 14.4 without frigging either Win 7 or 
adding even more partitions to the HD

I guess I could just try but seems better to ask here first, up till now I 
have 
always had a dedicated system to test Ubuntu on
