I've recently downloaded a Xandmod (5.15) kernel to try to see improvements in certain games.
When I installed it, I was told by others that I could simply pick the kernel the moment I install it on the GRUB menu, in case I ever wanted to roll back.
The problem is I realized that on my laptop with an encrypted disk, I never see the GRUB menu. I haven't since I installed Zorin.
First, I get the encrypted password login screen, and after that is succesfully entered I get sent immediately to the Zorin login screen for the OS.
Obviously, GRUB is not reachable for what ever reason.
I tried changing the boot order to show "grub" first before "ubuntu", and all I get is a Dell "pre-boot system performance check", performing a system scan. I don't get the actual grub menu displayed.
I know for a fact that it "should" work, because I also have Zorin on my main Desktop, also with an encrypted disk and the Grub does indeed show up.
Is there any way to repair this situation so that I can freely choose the kernel that I want to use?
