Manjaro how to do grub reinstall on a non booting system

the chroot wiki bit assumes you’ve got a unbootable system and are looking for a rescue, hence you’re reinstalling grub. You can do so from your terminal at any time, which will install the current grub package: sudo grub-install followed by: sudo grub-mkconfig

r/ManjaroLinux on Reddit: Repair Grub easy GUI way?

September 21, 2019 -

When I used Linux mint there was a easy way to fix the grub loader by using the boot repair package and you just had to install it and run it and it did its thing. Is there a easy way on manjaro? I have installed Windows 10 and then after installed Manjaro both in UEFI mode but when I boot my computer I get no dual boot option and it boots right into manjaro.

UPDATE: Read post below.

r/ManjaroLinux on Reddit: Correct installation of GRUB for dual boot with Windows 10 using Manjaro Architect

January 22, 2021 -

Hello everyone!

I am trying to install Manjaro along with Windows 10 in a configuration like this:

Disk 0 partition 0-4: Windows 10 stuff
Disk 0 partition 5: Manjaro
Disk 1 partition 0: Shared data (NTFS)

However, even after installing Windows and going through the process of installing a custom system with Manjaro Architect, I can't for the life of me figure how to use GRUB to dual boot. I try to mount on /boot/efi the partition that Windows 10 creates for booting, and then installing GRUB without formatting the partition. After that, my system boots to Windows and no GRUB prompt appears.

I have seen many tutorials on how to dual boot Manjaro and Linux, but all of them are using different flavors of Manjaro instead of Architect, which is the one I use for a really custom and minimal installation.

Any help on this? I would really appreciate it. Thanks!

You need reinstall GRUB. This worked for me: Boot into Manjaro installer Open terminal sudo manjaro-chroot -a (and select system to mount) grub-install /dev/sda (it's sda for me; make sure you choose the right drive!) grub-install --recheck /dev/sda update-grub exit and reboot When GRUB is back you may not see Windows in the list. If that happens just login as normal and run update-grub again. It will then detect everything and add them.
