I'm fairly new to Linux so fancy lingo will need explaining :-)



Updating Ubuntu from 13.04 to 13.10 has resulted in a black screen after selecting Ubuntu in GRUB. I can still select any other operating systems in GRUB without issue including Ubuntu's Recovery Mode.



My current GRUB2 options are:



Ubuntu (<-- this is the one that black screens, 13.10)
Ubuntu Recovery Mode
Memtest
Mint
Mint Recovery Mode
Ubuntu (different, old install, 13.04)
" Recovery Mode
Windows 8 (here at the moment)


A bit of searching suggested that it's a kernel issue with UEFI; my motherboard has no compatibility options so that's a no-go. There's also no "Previous Linux Versions" option/submenu under GRUB.



Is there any way of updating the kernel from the recovery menu? Or rolling it back? Or is it a completely separate issue?



Help appreciated.

Fixed it. Turns out it was an issue of my own creation with /etc/fstab. These are the steps I took to fix it:



1) Boot into Ubuntu's recovery mode and select the option that provides access to the root shell/terminal/command-line.



2) Enter the following to provide write access to the drive (incl/ crucially fstab):



#mount -n -o remount,rw /


3) Next you'll want to open fstab in nano (think of nano as the shell equivalent of gedit):



#nano /etc/fstab


4) Remove whatever you added there to cause the problem or comment it out with a hash (#). Hit Ctrl+X, then Y, then ENTER, or whatever other combination of keys (there's a guide at the bottom) allows you to save and write the changes and exit.



5) Enter the following to cleanly reboot. It may take a moment.



#shutdown -r now


If your problem is anything like mine that's it fixed. :-)
