My goal is to dual boot manjaro with windows 10 on two nvme drives. Laptop is xiaomi notebook pro. After installing windows on drive 1 i install manjaro on drive 2, and specify that the esp is in drive 1 (the windows esp). After manjaro install only windows loads, can only get into manjaro via installation usb with option to find other bootloaders.

Verify that you have all 3 partitions in /etc/fstab (they should be, normally)
Follow this tutorial to add a boot entry for Manjaro to UEFI

If it fails with the first try, read all special cases in that Tutorial topic.

I agree with this, I had a terrible time trying to get uefi to boot grub properly but the above tutorials are awesome. Also I find Windows uefi bootloader likes to override grub. Usually easier to have you manjaro install on the primary drive you boot from and have the boot loader there. That way grub can boot the windows bootloader if you want to start windows. And if the grub gets broken the windows boot loader will be on the other device ready to load. If you catch my drift.

#4

Do you mean, having one esp on each drive?
Have you tested/tried this?
How does it work with boot order?

#5

You can also have 2 or more $esp on the same drive.
And agree, having windows on a different $esp (from linux) is a damn good idea.
So windows cannot mess around with out linux $esp.
I have 4 $esp's on each drive.

Make sure you do

sudo cp /boot/grub/x86_64-efi/core.efi /boot/efi/EFI/boot/bootx64.efi
sudo efibootmgr -c -d /dev/nvme0n1 -p 2 -L “manjaro” -l “\EFI\Manjaro\grubx64.efi”

I reinstalled windows with its own esp then manjaro with a new esp on its own ssd, however the result was the same.

SOLUTION:
I booted with the installation usb and launched gparted, there i noticed that the esp i setup for manjaro had lost its boot and esp flags that were set on installation. If in gparted you re-apply those flags and apply the pc recognizes the second esp and gives you the option to chose os on boot

Did you checked with UEFI settings? Usually they don't change so they are set to use Window's EFI so either you must switch it to use Manjaro EFI partition or create a new boot entry with a path to Manjaro EFI.
People too often assume that after installation grub will be shown automatically.

#8

It looks like a bug to me. Which Manjaro installer have you used?
ISO name, calamares (version), M-A (version)

#9

You fixed it?
If Yes, good. Take care.
If No, use the link that petsam provided and provide info as required in that link.
We'll fix it. We just don't know if you fix it.
