Add Windows to GRUB

triss · December 29, 2024, 3:34pm

Good afternoon folks!

I’m quite new to EOS & Arch generally, but have been using Debian-based & OpenSuse distros for more than a decade.

I am used to dual-boot with Windows (sue me, I sometimes need some tools they only provide there), but I can’t find the W boot entry in GRUB.
I’ve been browsing the forums for some times, yet, I haven’t managed to solve my problem.

Can some wizards help me out?

Here are some info:

I think you need to remove all those old linux distro entries with efibootmgr.

Example: sudo efibootmgr -b <bootnum> -B

Edit:
The next thing to do is in the boot loader configuration file uncomment this line.

# GRUB_DISABLE_OS_PROBER="false"

Then run the grub update command.

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

This Arch wiki article might help you.

IIRC, you can use os-prober for that. You would have to change a setting inside the configuration file for it, after you install the package. Regenerate GRUB and its entries afterwards. I would say, however, that it isn’t advised to do that, as Windows and GRUB don’t like each other very much. Very likely, you have a boot entry in your BIOS menu for Windows. You probably should use that if you don’t want to wake up suddenly with a non working OS.

This is a completely other topic. Maybe say that after you’ve helped him out/tried to.

I’ve enabled os-prober in /etc/default/grub & ran sudo grub-mkconfig -o /boot/grub/grub.cfg

Rebooting…

triss · December 29, 2024, 4:20pm

Well, things did not turn exactly the way we expected!

but I still have an access there:

the 1st entry brings me back to the “UEFI firmware setting GRUB”
The 2nd & 3rd to EOS boot menu

ricklinux · December 29, 2024, 4:23pm

The one say’s arch? Did you have arch installed before? Did you try the one that say’s linux boot manager?

triss · December 29, 2024, 4:25pm

“arch” leads me to the “empty” GRUB
“linux boot manager” as well as “windows boot manager” lead me to the EOS GRUB

ricklinux · December 29, 2024, 4:27pm

I guess what you’ll have to do is boot on the live ISO and arch-chroot. Then reinstall grub and run the update grub command.

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

Do you know how to arch-chroot into the installed system?

Edit: arch-chroot

Not sure why this happened? It’s a UEFI thing. Par for the course.

triss · December 29, 2024, 4:32pm

Nope! But I’m willing to learn that!

I’ll try that:

chroot through the live-CD
run the following commands: sudo grub-install then sudo grub-mkconfig -o /boot/grub/grub.cfg

Am I right?

ricklinux · December 29, 2024, 4:36pm

The instructions for arch-chroot are in the wiki link i gave you. It’s simple really. You just have to boot on the live ISO and then mount the root partition and the efi partition that is boot with the correct commands and path. Then arch-chroot into the mount. It’s explained in the wiki depending on your set up which i hope isn’t elaborate. There are instructions if you are using btrfs or ext4 etc.

Edit: Need help just ask.

You could post the output for lsblk

Edit: Example of how arch-chroot is done.

sudo mount /dev/xxxx /mnt
sudo mount /dev/xxxx /mnt/boot/efi

sudo arch-chroot /mnt

ringo · December 29, 2024, 5:15pm

Online install without installing endeavourtools and config?

Or just install with arch?

triss · December 29, 2024, 5:16pm

Not sure indeed what to do there: my / partition must be the one labelled "nvme0n1p3

But when I try to mount it, I got an error

ringo · December 29, 2024, 5:17pm

Mis a letter

gruen · December 29, 2024, 5:20pm

“n” missing

edit: sorry ringo, I’ve been late

triss · December 29, 2024, 5:23pm

Well done folks!
My old eyes are not what they were!!

May I ask now what I should do?

gruen · December 29, 2024, 5:30pm

you have to chroot

ringo · December 29, 2024, 5:31pm

Sudo grub-install , make a new entry if yiu cleaned it up
