How can I install Ubuntu Sway Remix alongside another OS?

[hariganti]

I already have Ubuntu installed and I reallocated 60 GB for Ubuntu Sway Remix. I wanted to see if I could get encryption working with it without fully committing since Ubuntu 22.04 is capable with LUKS2.

I gave it a shot and it went incredibly poorly (queue the warning from the README). It does seem the installation itself was successful, and I was able to boot into my original Ubuntu installation, from which I used timeshift to fix my bootloader.

Is there a way to install Ubuntu Sway Remix and add it as a menu entry to an existing GRUB2 installation? My current setup is clearly capable of handling LUKS partitions, so I think it could work, but I need to avoid destroying my boot and EFI partitions during the setup process.

Thanks in advance!
