view full story

http://askubuntu.com – I upgraded from 10.04 to 12.04 LTS. Upgrade went fine, even restarted couple of times. Then the next day while booting into Ubuntu, after the grub, it gave the error 'Kernel panic : not syncing vfs unable to mount root fs on unknown block (0,0). I then booted into live CD and tried the following commands, based on other posts on this forum: sudo fdisk -l As the 8 was on /dev/sda1, sudo mount /dev/sda1 /mnt sudo mount --bind /dev /mnt/dev Now I got the message: mount: mount point /mnt/dev does not exist Then tried sudo mount --bind /proc /mnt/proc Again got the message: mount point point /m (HowTos)
