Dear everyone, I’m trying to install Manjaro in the following environment: Thinkpad T450s, grub2 dual boot Win10 and Debian. The operating systems are on two physically separate disks, Disk0 is for Win, Disk1 is for Debian. The win10 partitioning tool gives the following information (sorry can’t…

There are four choices for the bootloader location: a bootloader on the MBS of Disk0 a bootloader on the MBS of Disk1 System partition Do not install a bootloader. Based on your answer I’d think the fourth option is the right choice, and once the installation is finished, manjaro will just show u…

This seems to be the case as now I’m stuck at the grub rescue console.Before destroying everything on my laptop, can I simply reinstall manjaro with the bootloader option “MBS on Disk1” or should I try to solve the issues through the rescue console?

[image] jake77: Before destroying everything on my laptop, Nothing will be destroyed - you just cannot boot. Did you boot both systems through grub before? Then install grub to the system partition (as you called it earlier). and make sure you know whether Windows was installed in legacy m…

When installing Manjaro I did not have the choice fo…
