Same boat! I’ve switched over two of my lesser used devices to Mint already (an old surface tablet and my work laptop), only hesitation is with my gaming machine. Everything has been set up just how I like it so I’m not eager to start from scratch there but once I’m confident and comfortable on my work laptop I’ll make the switch there too
While dual booting into Pop, I can see my Windows SSD and all of its contents. It might make testing a little easier for you!
Running games from the NTFS partition won’t work very well/at all, you’ll want to redownload those to a Linux filesystem.
