Grub-customizer doesnt shows it

Can you still boot up Windows by bringing up your Bios’ one-shot boot menu?

What is the output of:
efibootmgr -v
?

I know i can boot windows with F12 for now, but i want it to enter into grub

$ efibootmgr -v

The output looks ok to me.

Just wanted to make sure that Windows Boot Manager is intact.

Given that you have followed the instructions in the dualboot guide, I’m afraid I don’t know what the issue might be.

Strange as well that Windows has disappeared from Ubuntu’s Grub boot menu too.

Please wait for other forum members to chime in!

I have a clue, my windows system doesnt detect any System partition (efi or boot) just the recovery one.

Also i installed endevour /boot partition at windows /efi partition beccause I installed there ubuntu’s

May I ask why you use the bootloader of both distributions (Ubuntu, EndeavourOS) at the same time? These are usually a problem. I would rather use EndeavourOS Grub in your place because EndeavourOS does not always appear in the Ubuntu boot. Anyway, follow this.

if you install os-prober and then update grub it should work. I had the same issue

@ismaelct

Did you run the command to update grub?

sudo grub-mkconfig -o /boot/grub/grub.cfg

this would be wrong. if I understand it right.

I’m also not sure what the OP means when they say they installed the Endeavour/boot partition at Windows /efi. There shouldn’t be a boot partition on UEFI.

Maybe the original poster has something similar to the one I had.
