Windows 11 not showing Ubuntu as a booting option in the boot menu
I installed Ubuntu in dual-boot along with Windows 11 and when I reentered into Win11, I can't boot into Ubuntu anymore. Win11 doesn't show Ubuntu as a booting option in its boot menu. I can't access into Ubuntu 22.04 anymore. This has happened to me several times in other laptops as well (that one had multiboot with Win7).
The way you can reproduce the same issue is by downloading and installing Ubuntu's latest version and then logging in, setting up some demo files, and then restarting the system to enter into Windows again. Now you can't enter into Ubuntu again because Windows has done something to it maybe.
