My Ubuntu is upgrading to 12.10 at the moment but since 4 hours or more I see only previous packages get restored and nothing happen. If I exit the upgrading now is all my previous data lost or does the Computer boot my old Ubuntu? I had a problem that is similar to this before while installing Linux on my fathers notebook. After the installation got crashed the Computer wasn't able to boot and I wasn't able to reinstall it. I need help I don't know what to do now.
