From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

1 are you using systemd-boot?
2 is your efi mounted as efi or boot?
3 depending on 2, manually unmount efi and see what you have on boot, maybe you have grub.cfg in 2 places.

When I had an /efi mount just as arch said on wiki I didn't have problems. /boot stayed with root system, so it can be booted with efi or mbr.
If you have 2+ disks and one has mbr the other is gpt you can boot from either bootloader.
You should also try limine, less headaches than grub.

I have windows with broken efi partition on another disk but that's not important, or is it?
To turn os-prober on see /etc/default/grub -> false and install os-prober, then run grub-mkconfig -o ..
@Hiro8811
Dosen't work. At first the partition was dirty no I managed to run chxdisk(or whatever its called) and can mount it without hassle but it still dosen't appear in boot menu. I think there's something wrong with grub.cfg since the theme is not displaying but I don't know how to solve it
The theme itself is defined in grub.cfg, but it may be the case that it is stored in your root partition not in efi, so during bootloading the drive can't be read from.
So if you manually change the location of the theme directory and copy it inside efi it may work, and change the position of in grub.cfg

I was looking through commands history and I noticed something. If I'm mounting efi in /efi but I save grub-mkconfig -o to /boot/grub/grub.cfg during boot grub won't even notice the config file since root is not mounted. Should I save changes to /efi/grub/grub.cfg instead? Or /boot/grub/grub.cfg is the place it should be?
root must always be mounted if you have a system, either by booting or chroot. If you mount just efi from another system .
On my setup /efi/EFI/grub only has the grub efi binary no config, /boot and therefore /boot/grub is on /root partition
Now if you have the entire /boot in the /efi partition then it would be /efi/boot/grub/grub.cfg?

Managed to get grub theme work so the grub is set up right. I guess I should stop being a help vampire. Anyway thanks for the help
What I meant is that during boot efi partition gets mounted before root so it wouldn't be able to get config files from root partition. But that's not the problem, I tried regenerating grub. Most likely it's something wrong with the theme I applied. It keeps saying that it dosent found grub and that it should be mounted either in /efi or /boot but it is mounted. I'll try with grub-customizer.
