No Windows option after Arch install

Toxyrock · 2024-04-25 23:29:59

Hi, I have two ssd one with Windows 11 and one where I just put Arch.
After installing Arch and putting grub as boot loader, the option for Windows boot manager no longer appears, not even in the BIOS where there is only UEFI OS as an option.
I tried to run probe-os and unchecked the GRUB_DISABLE_OS_PROBER=false in /etc/default/grub, but it doesn't detect Windows 11, what should I do?

Where did you put Grub? (Which drive)
What is the output of

efibootmgr -u

?

Sorry for the late reply:

Well, that is not what I had hoped. I was hoping to see an entry for the Windows boot loader as another boot entry.
What is the output of

lsblk

?

Also, if you enter the uEFI pre-noot menu (some people still call this the BIOS menu even though modern systems are uEFI), is there the ability to examine or change the boot order?

First choice would be to be able to tell the system that it needs to boot from the other drive.
Second choice would be to chain load to the other boot loader
Third choice is that the Windows boot loader needs to be rebuilt using a recover partition.

I can help with the first one and a half of those steps. As to trying to fix Windows, I am not your man. Have not even attempted that this century.

for the uEFI, there's only UEFI OS as an option.
I just checked the windows drive and there's everything, so i didn't accidentally erase it...
I'll try to rebuild the windows boot loader from a recover partition.
Btw I'm new to Arch, I literally installed it yesterday...

Can you tell your uEFI system to boot from nvme0n1p2 ? If that works, we may have a easy way forward.

In an ideal world, you would use uEFI boot menu to pick which to boot. Unfortunately, there are some really poor implementations of uEFI around that seem to be kludged together just enough so they will boot Windows. On the other hand, some machines, like this Asus Vivobook, have spectacularly good implementations.

Thx for the tip, i managed to solve by rebuilding the windows boot loader and upgrading Grub with probe-os.

Cool, glad you recovered. Now, can you boot Arch?

Toxyrock · 2024-04-26 20:02:36
