Comment 8 for bug 573776

Can you post some information on what partitions you have, what filesystems they are, and their mount points? In BootScreen.jpg it seems to show that dosfsck is failing to scan /dev/sda2, and is complaining with "Logical sector size is zero", which could mean some kind of corruption in the partition table. If /dev/sda2 is an important partition, the system may not be booting because it cannot mount it.
