After shutting down during a Ubuntu upgrade, I couldn't open my Ubuntu. It first gave me the following image on the screen. I should admit that's a beautiful wallpaper:

Ubuntu crash wallpaper

But then I turn it off again pressing turn the off button long and after trying to open Ubuntu again, it gave me a black screen this time. So what should I do? Is there a way to fix it?

Nope, I don't have that. – user1463542 Dec 22 '12 at 21:50
It is a nice wallpaper :-) – Jan Dvorak Dec 22 '12 at 21:54
It looks like a damaged GPU or GPU driver. – Jan Dvorak Dec 22 '12 at 21:54
I downloaded this ubuntu inside Windows so can i do something to fix it from Windows? – user1463542 Dec 22 '12 at 21:59

This looks like a CPU or GPU overheating problem. You need to check your laptop for signs of dust on its rear where the fan blows hot air out. If there is a lot of dust here you will need to bring your laptop to service, so they can clean it, and it will not overheat.

Then why there's no problem in Windows? – Jan Dvorak Dec 22 '12 at 22:06
Becouse windows has better hardware drivers and can precisely controls fans in order to prevent overhead. It's a common situation where worse drivers leads to overhead. For example, iMac with MAC OS will work fine even with games, but if you install Windows - it will overhead and hang :). – Eye of Hell Dec 23 '12 at 6:24
Why would that only start happening after a failed upgrade? – Michael Kjörling Dec 23 '12 at 14:11
