A few days ago I updated my kubuntu 11.10 to 12.04 via the update-manager. It asked me to restart, but now i cant boot my system anymore. When i try to boot, all i get is the grub menu and no matter which option i choose (i tried the recovery mode and every older version i had) all i get is
ata_id : HDIO_GET_IDENTITY failed for '/dev/sdb/': Invalid argument
and then it just restarts. When i remove the splash and quit option from the grub.cfg i see a few more lines before it restarts. Its way too fast to really read it, but i saw something about generel error mounting filesystems.
I cant even get to root shell.
Any ideas how to fix this problem via live system?
