Ubuntu won't boot afetr upgrade

[flaherty86]

Hello,
I just upgraded to 11.04. When booting, I can only start through "Linux older versions". Otherwise, with the first booting option, I only get "Ubuntu" on a fixed screen. Windows 7 also works fine. What can I do?
Thanks!
Lorenzo

[flaherty86]

which skip button? and at which stage of the booting / upgrading / ... ?

[dino99]

boot in recovery mode and select "repair packages"

[flaherty86]

Done. But that actually doesn't change anything...

Now it boots, BUT it seems to take MUCH longer than with the previous version... And it shows an NVIDIA logo which didn't use to show up before...
