When trying To Enter BIOS GNU GRUB Screen Appears

by Coel Riggs   Last Updated April 20, 2015 02:00 AM

I was trying to change my boot device on Ubuntu but when I hold F2 [the key to enter my BIOS] Ubuntu GNU GRUB appear. I would like to know how to enter my BIOS so I can continue changing my boot device.

Please help!

You should not press and hold, you need to press it repeatedly until the BIOS shows up on the screen.

If that does not happen F2 is not the right key for your system (it depends on the maker and model of your computer).

For those that might still stumble on this problem, the solution is:

When you start your PC, hold ESC, or you can hold ESC and then start the PC, doesn't matter.
A menu will appear. From there you can select which device to boot or to go into BIOS.

If you are to boot from a dvd or usb you can press 'c' at grub menu for a console then type exit and hit enter. It will boot on your dvd or usb. I was completely mad with this issue until I found this workaround.

This problem might be caused by the fact that one has acpi=off option in your grub.

To fix it:

  • change the GRUB_CMDLINE_LINUX_DEFAULT variable value from quiet splash acpi=off to quiet splash reboot=bios in your /etc/default/grub file

  • then please do sudo update-grub

Now you will be able to enter bios

However to make Ubuntu bootable again after you've change everything you needed in BIOS you should state quiet splash acpi=off in grub boot option (to enter it from GNU GRUB menu just navigate to your boot option (I guess it is Ubuntu) and press e)
