Some time between my latest update of BIOS (while using Windows) and playing around with Boot Order (to use a LiveUSB), my grub menu went missing. Previously, I was able to repair GRUB menu this way:
- Booting into Windows
- Going to Advanced Startup options
- Selecting my Ubuntu partition there
- Getting advanced restart -> Seeing my GRUB menu.
Then, I was able to select Ubuntu OS, log in, run boot-repair and get my GRUB menu back.
However, now after going through the boot-repair process, I still can't get my dual-boot grub menu back. My laptop keeps loading right into Windows.
Additional info: I also checked that the Boot Order's set up in the same way it was before I used a LiveUSB, it didn't help. I also tried some other combinations - without success...
I have Ubuntu 16.04 and a pre-installed Windows 8.1 on my PC. Secure boot and Legacy mode are disabled... and here is what boot-repair gave me the last time I used it:
I also use Grub Customizer to change the order of OSes in grub menu, but as far as I can tell, it has no impact on grub menu disappearance in this particular case. When I use grub-repair, and make no changes via Grub Customizer, menu still does not come up.
What could be the reason of this problem and how can I fix it?
