The messages on the screen when trying to boot are: |
| 97 |
|
| 98 |
* Checking root filesystem |
| 99 |
ext2fs_check_if_mount: Can't check if filesystem is mounted due to |
| 100 |
missing mtab file while determining whether /dev/da4 is mounted. |
| 101 |
fsck.ext3: No such file or directory while trying to open /dev/hda4 |
| 102 |
/dev/hda4: |
| 103 |
The superblock could not be read or does not describe a correct ext2 |
| 104 |
filesystem. |

|
| 107 |
* Filesystem couldn't be fixed. :( |
