I was trying to install Linux LTS using AKM. After installation, I noticed that I had a lot more “stuff” in my grub menu. Uninstalled Linux-LTS and came back to this.
From what I can tell, Linux Linux is just the default Linux kernel I already have installed.
Can someone help me identify who this new Linux is and how to get rid of him?
Thanks.
P.S Additionally, I would also like to know, how to completely skip the Grub menu, but still, have access to it. The idea is that I would immediately boot to Linux(maybe even Linux-zen). If I need to fall back to my LTS kernel, I would hit a key during the boot process to trigger the Grub menu, similar to how you hold the space bar to enter the systemd-boot menu. Is such a thing possible? Thanks.
Another way to boot your desired selection from the GRUB menu is by setting:
GRUB_DEFAULT=(then 0 or 1 or 2 or 3 etc etc. Look at your GRUB menu during boot. The top entry is 0, the next 1 and so on)
To do this edit /etc/default/grub with your text editor and save it. After this update GRUB and you are there. To change, just change the number.
There is an AUR package called “update-grub” which you can do sudo update-grub with, or do what @ringo suggested to regenerate GRUB.
There is a lot of info in the Arch wiki about GRUB. Most of the customising can be done by editing that /etc/default/grub file. It really isn’t necessary to use grub-customizer.
