Hello. I’ve been having some issues regarding the boot manager in my drive, as it seems it doesn’t recognize any OS while executing
First, some context. I wanted to install Endeavour into a removable ssd drive, so I can take the OS with me and use it when I’m in school and when I’m home.
This is because the school uses computers that are poorly maintained, while using a very restricted Lliurex OS. This way, i can keep my own versions of the programs that I need with the added benefit of ensuring compatibility at home.
Until now i’ve been using Manjaro for this, and it went fine until it started breaking after every update. So, I gave a try for Endeavour, since with regular testing it broke way less.
At home, it worked as it should. However, back in school the computer didn’t recognize the boot manager for Endeavour, only the Windows boot manager (at home I have a Windows).
After that I booted into a live version, and tried to fix it. I chroot into the system (with boot mounted), and used the commands
grub-mkconfig. The grub-install went correctly, as now i could see the boot entry in the boot order. But the mkconfig could not generate the entry for the Os, so the only entry was “UEFI firmware settings”.
I’ve tried to add my own custom entry in the grub.cfg to refer to Endeavour using the UUID, but I couldn’t find any vmlinuz and initrd.img in the /boot directory. Is that a problem or am I doing it wrong?
Is there a way to be able to rescue the boot and be able to use it in both computers? i fell that reinstalling will not solve the issue.

i can’t access the school computer right now, but it has only one drive. And it is a desktop with an i5-4th gen, integrated graphics and 8gb ram.
EDIT: tried again and i was able to boot into it at home after using
grub-mkconfig. However, i still feel that tomorrow i’m going to have the same problems. Any ideas?
