To add, if you look at the very first screenshot at the top of this thread, you can see that even if I provide a swap on drive 1, it will try to format swap on drive 0 as well.
I am honestly baffled. I really am. Of course, I am no Guru and there is plenty I do not know about Ubiquity Installer. But given all the information you have provided; I cannot understand why it is acting as it is.
I took a look around the internet hoping to find some answers. I find threads and posts asking about similar issues and the replies all dance around the topic without answering. Some replies say, "You can just install without selecting a swap partition" - Like it's that easy, with no explanation as to how and no further replies in those threads.
There are two separate issues here:
It is not clear or easy how to stop Ubiquity writing to EFI boot on to drive 0. It seems that it does this by default and IMHO this is a terrible idea which, on a multi-OS system, binds one OS to another (x). However, the way to overcome it is with the Something Else option, which I have now figured out.
With the "Something Else" option there is a definite bug in which Ubiquity will erroneously write a swap partition to another drive, at least with my hardware setup. Nor can I simply/easily disconnect or pull out my drives during an install because they M.2's somewhere behind my mother board.
Thank you for your input. It looks as if the only way I could proceed is to blow away my primary Pop OS in order to install Zorin on drive 0. This is a pity, as I wanted to fully test Zorin first as I've spent a lot of time getting Pop OS set up.
x. I've discovered that, although based on Ubuntu, Pop OS uses systemd-boot rather than grub, which seems to play much safer with multi-OS systems.
Does your system have Intel Rapid Storage Technology? If so, you need to boot into windows and disable it.
There is no Windows on this computer. In any case, I settled on Fedora + ArcMenu.
Thank you for all your help. Wish you all the best with Zorin.
Not a bad choice.
@Marlin I have in the past used Gparted to prepare swap, / and, /home partitions then use "Something Else" method for dual-boot. But that is Win/Zorin dual-boot. The only problem I have had with Something Else method, was fogetting to set the mount point on one occassion.
I refer to this (old but good) guide to that process, as I am not in the habit of frequent installs.
