Having trouble with EFI dual boot

usr238 · 2017-11-03 10:04:21

The problem is after I set up a UEFI dual boot with Windows 10 and Arch when I boot it goes right into Windows ignoring grub. To boot into grub I hit F11 to get into the boot loader selector where I have 2 choices Windows boot loader and then Arch boot loader. I select Arch and am booted into grub. Immediately booting into Windows is the default behavior.

What I hoping for is to just for the PC to boot to grub, in grub I do have 2 choices Arch and Windows.

In my bios there is a section where you can pick your boot loader and once you save your bios changes it will default to that boot loader, Arch isn't listed but Windows boot loader is.

I'm not sure how to proceed from here.

My experience level is a casual user of Arch, if I have instructions I can usually follow them.

So what have you tried to do to fix this? What Wiki information have you searched for, and what did you attempt to fix the issue? You're new to the forums, but Arch requires work on your part. (Note, I'm not implying you haven;t done anything to try and fix this, but if you have you haven;t told us.)

Start here, try to fix the issue, and if you have specific questions then list them along with the accompanying information about what you've tried, what happened, etc.:

You need to provide more information, too. For example, how are you handling secure boot? What does efibootmgr -v say? And so on.

It sounds like your boot order is set with windows first but that it does include entries for both windows and arch. You can use efibootmgr to change the boot order. The efibootmgr man page does show the example of how you can see the boot order

# efibootmgr -v

and how you can change it.

# efibootmgr -o 1,2,3,4

Okay, I found what was wrong. In my BIOS there are two places you pick the boot loader. There is the select drive boot loader and under that is another pick list where you can select which partition to boot, mine was set to Windows Boot Loader, I changed that to Arch Boot Loader and everything is working as expected.

How do I mark this as solved?

Thanks guys.

sudo efibootmgr -v

I set the boot order with

sudo efibootmgr --bootorder 0000,0002,0001,0004,0005

But it doesn't save it, after a reboot it goes back to

0002,0000,0001,0004,0005

Fast boot is disabled. I couldn't find an entry on Secure boot in the BIOS. There was a Windows section in the BIOS with things like Windows 10 WHQL which was disabled as default.

You have a different UEFI flavor than I do but I have experienced the problem with my changes not being saved. I haven't updated my UEFI in years but somehow it never happens to me now and I mess around changing between boot loaders a lot. I do use su instead of sudo, maybe that is the difference but I have nothing to support that really.
