11.10 upgrade problem

[Kmob810]

I have a dual boot system with Vista and today upgraded to 11:10 using upgrade manager. Unfortunately I cannot now open Ubuntu.
After trying to log on I get the following 'waiting for network configuration' and then 'waiting up to 60 more seconds for network configuration' start up then stops and the screen remains blank.
Can anyone help?

Please
(I cant get onto Ubuntu to use it) :confused:

i get the same issue with an dist-upgrade system (not fresh install) and can goes on if:
- i hit "esc" key when seeing this message
- or comment out all entries into : sudo gedit /etc/network/interfaces
(they are no more needed as the system directly deals with network now.

Thanks for your attempt to help dino but unfortunately nothing I have tried has got me past the blank screen. I still cannot get on to Ubuntu. It looks like I will have to revert to taking it off my system and go back to using Vista full time.
One last attempt:
is there anyone in Ubuntu/Linux land we can help me with this problem ??????/
Please
