@spiegelmama not sure on that one yet, but while you are in the bios disable fastboot just in case. I assume Windows was or is still also installed on there? Apparently, there are instances where fastboot doesn't completely shut down Windows, and it still has control of the networking.
@spiegelmama Ah, this most helpfully is mentioned here: https://docs.bazzite.gg/General/issues_and_resolutions/#no-wi-fi-or-wired-connection-in-bazzite-when-dual-booting-with-windows
@jared Thank you for talking me down! I was panicking not a little. Right now the laptop has crashed, possibly due to overheating? I'm letting it rest for a little while and then hitting it with this new knowledge. Woof! This is not easy. I guess I didn't expect it to be, but it's much harder than I thought. Guess there's a reason people don't switch much. 😁
If I can get this done, and do a dual boot on my laptop, I'll go out into the world and be an angel of knowledge. Glad I at least know to photograph any error messages.
