I have a tri-boot computer (Ubuntu Mate 16.04.3LTS, Windows 7, Kali Linux). Until recently, grub menu showed at every boot just fine. However, tonight, I decided to exit Windows and load Ubuntu; I noticed that the grub menu never showed up and it just loaded automatically into Ubuntu. At first, I didn't think anything of it, because that's where I wanted. But now I can't get back into Windows.

I have tried:

  • holding the shift key during boot
  • running grub-update
  • interrupting the boot process with ctrl+alt+delete
  • performing boot-repair (log available at http://paste.ubuntu.com/26269885)
  • and changed the etc/default/grub line25 by deleting the '#' from front of line "GRUB_GFXMODE=640x480" (and running grub-update again)

I don't know if this is related but i also noticed that when I reboot my computer, the Dell logo doesn't show up on screen either

Reading information on pastebin, I found out that

GRUB_TIMEOUT=5

edit GRUB configutaion by running

gksudo gedit /etc/default/grub

in terminal. Enter your root password, then edit

GRUB_TIMEOUT=5

to

GRUB_TIMEOUT=10

Save the configuration file and run

sudo update-grub

This should solve your problem.

  • I'm not sure why the pastebin showed GRUB_TIMEOUT=5. I just checked that file and it says GRUB_TIMEOUT=10. And the problem still persists – Tricia Young Dec 28 '17 at 13:01
  • Try increasing that number to say 30 seconds. – TheOneAboveAll Dec 28 '17 at 15:26
  • @TriciaYoung | Answer provided by is same which I said, just it increases the timeout a bit more and uses GUI. You are requested to please accept my answer too and upvote it. – TheOneAboveAll Dec 28 '17 at 15:33
  • Actually it wasn't the time with the GUI. In the GUI there was no check mark in show menu. And I had increased the time in that file, which still had not worked. Furthermore, it only worked that one time. I have, since, rebooted the computer again, and it no longer is working. – Tricia Young Dec 28 '17 at 23:33
  • HAve you tried reinstalling GRUB – TheOneAboveAll Feb 18 '18 at 10:14

  • Update: It worked once. But I have since restarted, and now it is back to loading automatically to Linux, with no grub menu. I went back into the grub customizer, and all the settings are the same as they were before when it worked. – Tricia Young Dec 28 '17 at 23:30
  • Do just as this picture : – Dz-Source Jan 1 '18 at 16:53
