Hi, the problem is in your fstab: You try first to mount /boot before mounting root "/".... Cant work... Try this one: /dev/sda3 / ext4 noatime 0 1 /dev/sda1 /boot ext2 default,noatime 0 2 /dev/sda2 none swap sw 0 0 /dev/sda5 /home ext4 noatime 0 2 /dev/cdrom /mnt/cdrom auto noauto,ro 0 0 best regards, mcc
