And I'm in despair.
Trying to make wine work, used POL, and etc. I managed to make wine run with Roller Coaster Tycoon. I didn't install anything major. It may be relevant that I was downloading a torrent before (legal, free torrent, PWO in case you were wondering) Then, as my daily-work-on-ubuntu work drew to a close, I hit update manger or whatever it's called, and it basically tells me it broke itself and only wants to do partial updates. I was like, okay, fine, no biggie, the partial updates will probably fix it. They didn't, and it kept freezing. PLUS it removed wine for whatever evil reason. So I do it again, and it says it has more partial upgrades to install. And again. At this point, I googled how to fix it. I did all the standard stuff to troubleshoot this. All that stuff in terminal said nothing was amiss, and I was tired, so I called it a day.
When my sister wanted on windows, Ubuntu did not want to restart. I did ctrl+alt+delete+delete and it restarted, and windows worked fine.
I booted up the computer and Ubuntu is no longer on the GRUB menu. Only windows 7 and two memory tests. I did not install any large files or new versions, I've been using Ubuntu 10.10 since I switched from windows like two weeks ago. Reading up, I learned that Partial upgrades can really eff up my system, so I'm guessing they are the culprit (thanks for the heads up, update manager >.>)
What can I do at this point to get Ubuntu back with as much of my data as possible?
