Guide: How to install Windows 10 onto storage expansion card

Rufus has a “windows to go” preset, and I used that preset to install a normal w10 ISO to my storage expansion card. Worked very smoothly.

I just followed the directions given in the OP above, and a 256G Expansion Card. It worked fine on the 2nd try (probably typo’d the first one). Used a USB that I created from an existing Windows install. Disks look like this on Unix (OpenBSD, which as my main system is on the SSD):

I was able to follow the guide and install windows (after jumping through some hoops)- but now wifi and sound don’t work on my pre-existing manjaro installation.

I tried disabling fast boot in the bios, but no luck. Any thoughts?

Edit. I also disabled Windows fast booting in the power settings, no luck.

It wasn’t until I stopped rebooting from one OS to the other that I got my network back on Manjaro. Have to fully shut down Windows, wait for a few seconds, and then boot into Manjaro, and wifi would be fine then.

I don’t understand. Do you put Windows into hybernation? sleep?
I believe Windows saves some data (on the disk, maybe in BIOS too) that lock the state of certain things (should only occur in sleep tho, hibernation is next to a full shutdown)

Could be anything. The wifi card could simply be in some unexpected state that the linux driver doesn’t know how to reset out of. The clue is that staying powered off for longer time makes any difference. That means the card isn’t reset until all the caps on the power rail drain.
