I have an Asus F555L model with dual boot (Ubuntu 18.04 LTS and Windows 10).

On starting my computer, I always get the option to choose between OS from the GRUB loader. However, my battery was swelling, and hence I removed it and replaced it with a new one.

Since I have done this, my computer directly goes into Windows. I do not get the option of choosing from the GRUB loader at all.

Disabling Fast Boot from BIOS hasnt helped. I have also tried pressing, Shift, Space and ESC on start but none of them helped.

I also tried putting the old battery back and it doesnt show up on that either.

What other options do I have to get my Ubuntu OS back with all my files and programs?

The output of efibootmgr -v revealed that the boot-entry for Ubuntu is broken, so I recommended to make use of boot-repair which fixed the issue.
