Install another distro alongside EOS with Btrfs volumes

[Reiner_Sanders]

Hey guys,

i wanted to install another distro alongside my current EOS install, which is in a Nvme SSD. I am using Btrfs filesystem.

I tried to install the live cd of Debian, for example, but there the partion tool does not gives me an option to install in the same partition the current distro is without to erase all data.

I have previously created subvolumes for the new / and /home, but I can’t see none of them when in the installer.

My question is, is it possible to do this, while maintaining GRUB at where it is now (/boot, in a separate partition fat32), so I could boot both distros?

It is possible but most installers don’t support installing into an existing btrfs volume.

I have done this in the past by installing into a VM or a separate partition and then sending the snapshots of the install into the target system. Then you can chroot in and get rebuild the initrams. Then update the main bootloader.

Oh, great idea! Thank you very much, @dalto .
