I recently installed a lot of updates for Ubuntu 10.10, since 11.04 didn't work on my system (Lenovo x201).
Today after the update, grub still exists and lists all OS on boot-up. Starting Windows 7 is no problem but starting Ubuntu just does not work. When starting Ubuntu the system comes to the loading screen, but it shows no HDD activity (no HDD-activity light). It just stays that way.
I really need to get the system running ASAP.
I already tried this HowTo but it didnt worked.
