I can only boot into Ubuntu by first booting from my live USB and changing the boot drive in grub. I.e., not from a hard disk installation. After booting re-booting by changing disk priority in BIOS is flawless.

Throughout the history of this problem I get a variety of errors: Out of disk, 'Unknown filesystem' (my current error). I've tried fixing it by re-installing GRUB, by using boot-repair to re-install GRUB, and several other methods, with no results. Thank god you don't need to shut Ubuntu down frequently.

Under are the results of fdisk -l

  • Do you mean "out of free disk space"? Maybe you can delete some old kernel images from /boot... – davidbaumann May 4 '15 at 18:21
  • @Jesse Run boot-repair like this – Mudit Kapil May 4 '15 at 18:44

What might have happened

GRUB could have been installed on your USB stick.

How can I (potentially) fix it?

  1. Type in Ctrl + Alt + T
  2. Type sudo apt-get install grub2

Please tell me if this didn't work, because I would like to try to help again.

  • I had tried this in the past without effect, and have tried it again. No result and same output from fdisk -l – Jesse Huisken Mar 28 '16 at 16:06
  • @JesseHuisken Sorry for your loss. – lolreppeatlol Mar 28 '16 at 16:18
  • My loss? Minor inconvenience. Thanks for trying to help regardless. – Jesse Huisken Mar 29 '16 at 4:35
  • you need to mount and place Grub to the start of partition – Mudit Kapil Mar 30 '16 at 7:57
  • may be you need grub-rescue – Mudit Kapil Mar 30 '16 at 7:59

1.) choose Try Ubuntu from Live CD

2.) launch Boot-Repair .

3.) click Advanced option

4.) go to the GRUB options tab

5.) tick the out-of-disk option

6.) click Apply

reboot the System.

If this did not work try from terminal sudo apt-get install grub2 when your system boots-up and then use Grub-customizerto place it on /dev/sda1.Install Grub Customizer in Ubuntu 14.04 to Manage Your Grub Bootloader

  • This proved to be ineffective. – Jesse Huisken Mar 26 '16 at 3:52
  • @JesseHuisken Then try and search in AU and Google for the solution or start a bounty on you Question – Mudit Kapil Mar 26 '16 at 5:32
  • @JesseHuisken I just had lost 100 reputation may be ask someone and request in a chat room to do this for you. – Mudit Kapil Mar 26 '16 at 5:36
  • @JesseHuisken By the way /dev/Sda5 is your Swap did you created yourself what are your system configuration.? – Mudit Kapil Mar 26 '16 at 5:47
  • @JesseHuisken I've started bounty :) – Mudit Kapil Mar 26 '16 at 6:40
