I updated my motherboard and now can't boot. Can someone help me repair my boot thing?

I’m not sure what happened. I updated my motherboard and now my computer tries to boot into windows.

I do have windows (rarely use it) on a separate drive. But why am I not able to boot into EOS?

Is there a simple way of fixing my boot menu and stuff? How can I see grub again.

with this new mother board did you remember to go into the bios and turn off secure boot

Its not a new motherboard (sorry poor wording on my part, I updated the bios).

But annoyingly, it does restore defaults whenever I update and so I did disable secure boot.

It for some reason is trying to boot windows (and I just went and checked, I deleted the windows installation months ago). I’m using the windows drive as a storage drive now

recheck all option in your UEFI motherboard

  • Secureboot desactived
  • no Fast , CSM or Legacy
  • all disk on AHCI

you will have to boot on USB live iso endevouros , if there is no more entry in efibootmgr

Yup yup and yup.

Also the computer can access the drive, but for some weird reason, when I installed windows, it put the windows boot manager on my linux drive.

Now that windows is gone, the comptuer can’t boot into it. But I sitll have a working Endeavour Os installation, that somehow has lost its grub menu with a simple bios update.

Even if I remove the windows boot manager option using “sudo efibootmgr,” it comes back on reboot (though now its Boot 0004 instead of 0001)

I tried removing the boot opiton and then recreating the grub menu on an endeavour OS live usb, but whatever I did, clearly didn’t work.

Edit: I think for right now, given time constraints and other various constraints, I’ll just reinstall Endeavour OS, but for future reference, if someone can give advice on how to rebuild the grub menu, I think I would appreciate it.

You can reinstall Grub from a chroot as described here:

Perhaps it’s too late for this time, but it’s a good procedure to be at least sort of familiar with because it does come up every now and again.

I would have done as @BluishHumility has posted. arch-chroot from the live ISO and reinstall grub and the run the grub update command.
