Cant get windows 10 & manjaro dualboot to work

Support
1

so ive tried installing manjaro to a new partition on my main ssd drive nvme
but my pc keeps booting into windows, and the only way to access manjaro is with my usb.
i for the life of me cant get it to just boot into manjaro or give me a bootloader or something.

ive done the following:

[manjaro ~]# lsblk

I’ve also tried running grub-install, and then update-grub but i still get the same errors

secureboot and fastboot are both turned off.

nvme0n1p6 is a 45gb partition for manjaro
nvme0n1p5 is 200mb for efi

Welcome to the forum! :wave:

Tip: When pasting terminal output on Discourse forums, one can either…

  • Highlight it and use the Preformatted text </> toolbar button.

  • Add three backticks ` above and below the text (Markdown):

    ```
    text
    ```

  • Use HTML:

    <pre><code>
    text
    </pre></code>

I’ve done it for you this time. :wink:

Hello,

from your partitions, I would say that your Windows is installed in BIOS mode, but you are installing Manjaro in UEFI mode. With a little more information, maybe we can solve this. Please post the output of these commands:

sudo lsblk -f
sudo efibootmgr -v
sudo fdisk -l

Also, if you want to mount your Manjaro from the live USB, you can just run manjaro-chroot -a. That will mount necessary partitions and chroot into root partition. But run those commands outside the chroot anyway.

So, I was wrong and your Windows installation is also in UEFI mode :slight_smile:

From the efibootmgr output, we can see that there is no Manjaro entry in UEFI. Your EFI partition (ESP) /dev/nvme0n1p5 is marked/flagged as “Microsoft basic data”. You should change it to “boot/esp” flag, with, for example, fdisk or parted (The flag it’s actually the partition type EF00).

After changing it, you have to add the Manjaro entry to the UEFI. The easiest way is just to reinstall grub:

grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=manjaro --recheck

This have to be done inside the chroot (remember: manjaro-chroot -a)
After that you can run sudo efibootmgr -v again to check that the Manjaro entry has been added. Reboot and check if it works.

PS: I didn’t said anything before but I suppose that you have already disabled Secure Boot in UEFI/BIOS, isn’t it?

PS2: The wrong flag comes from a bug in the 21.0.7 ISO when installing in manual mode. It’s fixed in the newer ISOs available.

There it is the Manjaro entry in efibootmgr. Did you rebooted? Still Windows?

Again, just to be sure. Did you disabled Secure Boot in UEFI/BIOS?

rebooted, it still boots directly into windows…
And yes secure boot is disabled :frowning:

Ok. Then it could be that your motherboard doesn’t like two ESP partitions in the same disk. I have seen that. Or it could be that even Secure Boot is disabled your motherboard is not standard compliant and refuse to boot from a non verified/signed boot loader. I’ve also seen that.

For the first case, while in chroot you should change Manjaro’s ESP from /dev/nvme0n1p5 to /dev/nvme0n1p2. I mean that you have to change the UUID of the EFI partition (ESP) in your Manjaro’s /etc/fstab to EC3D-3E67 and you have to mount this partition in /boot/efi instead of the old one. Then you run the grub-install command I gave you.

That’s number one. For option number two, you have to add the signature of the grub bootloader in the EFI partition (/EFI/Manjaro/grubx64.efi) to your UEFI BIOS. For that I can’t give instructions as it depends on the motherboard. Check the UEFI BIOS’s/motherboard’s manual if unsure.

I don’t know if there is anything else you can do. The entry is being added to the UEFI boot list but when you reboot, it disappears. That means that your motherboard doesn’t like something about it. Usually it is because most motherboards are “Windows-centric” and doesn’t follow the standards.

PS: You didn’t say anything but I hope you changed the /dev/nvme0n1p5 partition’s type.
