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

<br>
* Filesystem couldn't be fixed. :(<br>
