Literally finally let my windows partition upgrade to windows 11 last night. It took like 3 HOURS to do. Then I shrunk the partition way down and clean installed my Bazzite dual boot over the extra space and that took MAYBE 15 minutes. I use Windows MAYBE once every 6 months or so. Linux has just been the better experience for 99% of my computing and even gaming needs.

The bazzite project website has an explicit “how-to” for extra drives. Worked for me with no issues, though I am definitely more experienced with tinkering with that kind of thing.

Bazzite would be my suggestion. Throw the full install on the ssd then format the HDD for general storage. I’d be a little concerned about the 1060 3GB GPU though. Drivers will likely be fine, but the “10 series” have notoriously awful async compute and take a much larger penalty when running games/apps under proton/vulkan if I recall correctly.
