Installing Zorin OS over a custom partition layout (LUKS + BTRFS + Subvolumes)

Installing Zorin OS

Hello everyone. I'm trying Zorin OS 18 Core before going for the Pro version, and I'd like to install it over a custom partition scheme with LUKS+BTRFS and Subvolumes + Swap File.

I want to do this, because I have two disks, one smaller NVME drive, and one, way bigger SATA drive. I want to have "/home" and some "/var" subtrees in this bigger drive, and the rest in the the faster/smaller NVME drive.

Ubiquity installer does neither offer the options to create custom BTRFS partitions nor create subvolumes, so I did my partitions and subvolumes by hand. However, when I try to install it into the "@" (root) subvolume, it fails, saying that the partitions are mounted and the installer cannot modify the partition table of the disk.

AFAIK, Ubiquity uses the partitions mounted on "/target" to install the system. Given this, how can I make the installer to use my custom partition scheme?

Thank you in advance!

Welcome to the Forum!

First, I would suggest to delete the old Partitions. So, they are empty. Start Zorin on the USB Stick in Live Mode (''Try Zorin'') and search for GParted, open it and delete the Partions. Then start the Installer. And then create the new Partitions. Further, I would suggest to not use the @ - even when it isn't unconvinient to use it.
