I use Manjaro Linux as my main OS.
I also have Ubuntu and Windows installed on other partitions, and I sometimes boot into them.
I was using rEFInd (https://wiki.archlinux.org/title/REFInd) on top of grub for multibooting,
but even if I selected Manjaro Linux in rEFInd, the Manjaro Linux grub menu would appear again,
so it was inconvenient to have to press enter once more, so I thought about removing it,
and while I was doing what Claude suggested to change the rEFInd configuration file, a frustrating situation arose where the boot menu wouldn't appear at all.
Here, something went wrong, and I couldn't even access the UEFI settings menu of the BIOS.
In the end, I created a USB booting disk, and after a lot of trial and error, I finally restored it.
Even though I consider myself proficient in Linux, sometimes I get into trouble like this,
so I think that for novice PC users, Linux as a main desktop OS is not easy.
