to edit your fstab u can start linux recovery and ...
on the command line..
Code: [Select]
vi /etc/fstabit will start fstab.

Now press insert button so that u can do modifications in fstab.

Now at command prompt..
Code: [Select]
:save fstab
Is that wht u want?

use ur cd to linux rescue or use ur bootloader to go into the shell
if u use the cdrom type the command
Code: [Select]
chroot /mnt/sysimage

now u may do comand line editing by using vi or emacs as the case may be ur file is in /etc/fstab.

If u do mean vi then i do like this in Red Hat distro:

1) "Insert" key to enable u to type in the file u wish to edit. Then start typing :)

2) Now, press "Esc" if u finish typing.

3) Type ":" followed by "w" to save. ----> ":w"

4) Press "Esc" again and type ":" followed by "q!" to quit without saving. ----->":q"
   
      OR

Just press "Shift" + "zz"  (zz = press "z" twice) to save and quit vi.
