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 embed media):
Disk0. C: is Boot, Page File, Crash Dump, Primary Partition
Disk0. E: is Primary Partition
Disk0. D: is Primary Partition
Disk1. has three partitions. Total is about 224 GB, approximately 28 GB + 11,7 GB + 184 GB.
When installing Manjaro, at the step the disk for installation is to be chosen I chose disk1 and go with the option “erease partition” - this seems to be the right choice.
My question is: what choice should I make about the bootloader? I have absolutely no idea for this one, I’d appreciate any help.
If you erase Debian’s partition, you should also override its bootloader with Manjaro’s. Otherwise, your choice of not overriding it will be kept and the bootloader settings won’t be updated.
You can override it later, but you likely won’t gain anything by delaying that.
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?
The BIOS was earlier set to work both with legacy and UEFI, priorize legacy and CSM enabled. Debian was installed on the second disk and the debian-themed grub menu worked flawlessly - unfortunately I don’t remember how or where it was installed.
When installing Manjaro I did not have the choice for uefi or legacy.
Depending on the setting in the BIOS the laptop will now boot directly to Manjaro (UEFI mode) or to a grub menu missing the Win10 option (legacy/uefi with CSM). I’ll look into the option legacy only.
Choosing the boot drive directly did not result any change, I could not boot Win10 since the first time the grub rescue prompt came.
Perhaps not the best idea, but I started a new topic on the dual boot issue, when I saw the data being intact here. In that thread I included the output of some of the usually required commands - care to take a look and move this conversation?
