Thanks, re-installing Linux resolved the issue. Now both Windows and Linux work fine. But I have a few questions and I would be grateful if you could answer:
1) Should I avoid updating Linux again or it was just a "bad luck" accident, as you said? 2) How can I find out in which partition the new Linux has been installed. I tried to manually choose the same partition as the previous installation but received an error message. So, I let the system decide itself (the default option). I don't know whether now I have two installations of Linux or only one. (see the list below) 3) When I reboot the system I see the following boot list: Ubuntu with Linux 2.6.32-21-generic Ubuntu with Linux 2.6.32-21-generic (recovery mode) memory test (memory 86+) memory test (memory 86+, serial console 11520) Windows 7 (loader) (on /dev/sda1) Windows 7 (loader) (on /dev/sda2) Windows Vista (loader) (on /dev/sda3) Windows Vista (loader) (on /dev/sdb1) What info do you obtain from this? I'm wondering why I have two Windows 7 items?
