If you haven’t checked, it is possible that your BIOS/firmware supports something like Hybrid BIOS (or whatever name with your motherboard vendor, means support for both UEFI and legacy BIOS boot). Worth checking, it might help.
Fwiw, when you do an UEFI installation, the systems installed put their bootloaders in their own folders on ESP. In your case, EnOS would have just added a new folder with its bootloader alongside the other ones already on ESP.
I also have a 500 MB EFI partition.
You’re right, in the BIOS I can toggle between just UEFI, legacy, or both. Depending on the start settings, one or the other grub will start. Thank you.
In the meantime, the problem is solved, meters from the installed Kubuntu grub menu, EndeavourOS can also be started, although only in fallback mode. Thank you all for your constructive comments.
The quick and dirty way to fix the fallback thing is likely to be an incorrect entry by the grub os-prober from the other system. If you change the line:
initrd /boot/amd-ucode.img
(obviously if Intel powered, it will read /boot/intel-ucode.img) to
initrd /boot/amd-ucode.img /boot/initramfs-linux.img
in the file /boot/grub.cfg it will probably ‘fix’ the problem.
The reason this is ‘dirty’ is that the file WILL be overwritten on every grub update, and need to be ‘fixed’ again.
What I would do myself is install rEFInd, and let it do the whole thing. We have a wiki entry on that right here, and nothing is required beyond the install to see if it works.
BTW - I wrote the wiki, so I'm biased!)
Thanks for your valuable reply, I will give it a try. What is the disadvantage of fallback mode compared to normal startup?
The normal startup has been configured (using autodetect for example) for your system. The Fallback option skips autodetect, and leaves everything (including the kitchen sink) in the startup. It can help with tracking down problems with hardware, or misconfiguration for instance.
Thanks. This “dirty” method worked.
