To start off with I had a Ryzen 3400G and an MSI B450 Tomahawk Max that had become unstable and took several tries to boot. I decided to swap in an ASUS Prime B550M-A wifi.
The only issue is I was triple booting Kubuntu, Windows 7, and Windows 10, so this would be interesting.
TL/DR:
Kubuntu booted normally. Like seriously, just a regular boot, no messages or anything.
Windows 7 froze a few seconds into the loading screen. I tried rebooting and using safe mode, but that froze too.
Windows 10 gave a bunch of 'rechecking' and 'fixing file system' messages, and after about 2 reboots with more messages, opened to a workable desktop.
Lol I did this with 2 laptops that had different CPU generations and it still worked, haha. Had a laptop I was using as home server with a 2nd gen Intel i5, and a laptop I was using as personal laptop with an Intel core 2 duo and just took the drives and swapped them, everything booted normally, no problems. Linux is awesome.
