Edit fstab from Live CD

[ockham23]

ls /media

Maybe there's no "/media" directory. Replace "/media" with "/mnt" and try again.

ls /media

Let me explain how I got to this point in the first place. I had two partitions that Ubuntu nautilus could not see, hdb3 & hdb4. Gparted could see them. I finally got Ubuntu to recognize them, but then I could not get permssion. That was when I started tweaking fstab and the next boot failed, I could not and still can not boot into Ubuntu. That is why I am trying to edit fstab from a live CD. About the command above, do I use that command in knoppix seeing I can not boot Ubuntu or were you assuming I could boot in to Ubuntu ?

[ockham23]

This is from Knoppix, just to list the contents of /media. And, while you're at it, you could post the output of

sudo fdisk -l

root@1[knoppix]# ls /media

ls: /media: No such file or directory

Is this Knoppix 4.0 or an older version? Ok, check whether directory "/mnt" exists. If so, the commands are

su
mkdir /mnt/hdb6
mount -o rw /dev/hdb6 /mnt/hdb6
mcedit /mnt/hdb6/etc/fstab
umount /mnt/hdb6

Knoppix 4.0.2

[ockham23]

Strange, I have 4.0.1 and mount points are in /media. Anyway, /mnt will do as well (if it exists, that is).

Try this,

When you get the knoppix boot screen, type: knoppix 2, this will bott you into a command line and you are root.

Now from the command line, type: startx, this will start the xsession and you should be able to proceed, as root, in a graphical mode to peruse your partitions and edit /etc/fstab, wherever it may be without sudo first.

ok, good deal, I was able to access, edit and save my changes in hdb6 fstab with the above commands. Thank you so much for being patient and walking me through this. I allready have this post and the commands added to my library.

the knoppix forums are great,
