crashed while upgrading, now nothing seems to work

[qui8]

yesterday i started upgrading ubuntu 9.10 and then the computer was restarted in office due to reset button pressed accidentally. when i started the machine, now the network manager is gone, and other printer connection is lost (samsung scx-4300) now we dont know how to repair since to complete upgrade i need internet connection which is missing due to this crash.

can anybody help? i dont want to reinstall and loose all our settings, installed softwares and user info as well as printer setup etc. or is there anyway where i can just repair to previous version of ubuntu (restore to previous point) where things work as they were.

thanks.

Have you been backing up your system? If not, follow this link. (http://www.cgsecurity.org/wiki/TestDisk_Step_By_Step)
Otherwise, please indicate how you did your back ups.

In your System>Administration's menu you have your Network Tool. With this you can set uo your internet connection manually.
