So I have decided to try out BT4 on one of my laptops. I was able to install it with no problem, and everything seemed to be fine. However, as soon I as try to start up BT4 I encounter problems. The error message i get is FATAL: Could not open lib/module/2.6.32-21-generic/modules.dem.temp for writing: No such file or directory. After a few other messages it gives me a shell with the name (initramfs).

Other information:
My computer is an HP pavilion dv6500.
I know it runs ubuntu since that is what has been running on it in the past.
BT is not conflicting with any other OS since it is the only one.

If you need the full message it says I will type it up. (Is just a little bit long). I also believe the above message is the main problem.
