I cant login to Ubuntu.

The splash screen stuck after checking file system. I used "storage device manager" (pySdm) to mount drives at boot time and also changed some options in it (which I can't remember now).

Since then Ubuntu (12.04) is not starting.

If your problem is the the new drives you added, maybe you can boot into root, you can see this question How do I boot into a root shell? , edit /etc/fstab and check if there is anything wrong with the new disks.

If you don't find anything wrong, create a backup of the file (to be safe) and remove the new added disks entries, just make sure not to remove your Ubuntu partitions.

If you don't find anything wrong, try posting the contents of the file here maybe you can get some help with it.

Hope this helps

Did you manage to do the step and fall into a root shell? If your problem is the editor you can use pico to edit the file. just do "pico /etc/fstab" (don't forget to create a backup of the file "cp /etc/fstab /etc/fstab.backup") – j0N45 Aug 8 '12 at 8:14

Thanks to jON45 for his time. I've fixed fstab by logging as live user and editing fstab. the code used to login are here

sudo mkdir /media/mount<br>
sudo mount /dev/sd__ /media/mount<br>
sudo vi /media/mount/etc/fstab<br>

i must say that im a hero/computer geek in school. thanks to Jnlopes. webs to fix fstab,
