While booting, windows automatically gets started.

To use Ubuntu I have to restart by pressing the [Shift] key to get the grub menu.

Please help me fix the problem so that I can get the grub menu at startup.

  • Is Windows pre-installed? Then it is UEFI and you have to change boot order in UEFI. But some vendors only let you change to boot Windows entry. What brand/model system? http://askubuntu.com/questions/486752/dual-boot-win-8-ubuntu-loads-only-win/486789#486789 and: http://askubuntu.com/questions/507013/windows-8-1-changes-boot-order and: http://askubuntu.com/questions/244261/how-do-i-get-my-hp-laptop-to-boot-into-grub-from-my-new-efi-file – oldfred Nov 26 '14 at 04:54

Warning: You're going to edit grub (the boot manager) Don't change anything else then the lines mentioned in this post without further research first!

Once you're in Ubuntu, just open a terminal Ctrl+Alt+T

Type into the terminal:

sudo nano /etc/default/grub

Change the following line where iNumberOfseconds is the number of seconds you want to see the grub menu:

GRUB_TIMEOUT="iNumberOfSeconds"

If you want to see the countdown, change the value "true" to "false"

GRUB_HIDDEN_TIMEOUT_QUIET="false"

Then hit Ctrl+X to exit and then Y and Enter to save.

Next time you boot, no need to press Shift any more to boot to Ubuntu.
