How to enter GRUB menu on single boot Ubuntu system

Updated - August 16, 2019 by Arnab Satapathi

Here in this quick tip, I'll show you how to enter the GRUB boot menu while only one operating system, i.e. Ubuntu installed on the system.

  1. First Shut down your Laptop/Desktop.
  2. Next power it up again.
  3. Press and hold the Shift key soon after you see the UEFI /BIOS is screen.
  4. You should be able to access the the GRUB menu.

Alternative method to enter GRUB menu

If holding Shift key doesn’t work, then you need to edit the /etc/default/grub file, and find the line GRUB_TIMEOUT and edit it to below.

 GRUB_TIMEOUT=10
enter grub menu while booting

This will wait for 10 seconds before booting the default operating system.
