Dual Boot potatoes

[BigBadBeef]

I've finally gotten my fat, lazy ass to dual boot windows 10 with POP!_OS already being installed. It is, however, not going quite the way I planned.
I used USBImager to get the windows ISO loaded into a flash drive, now its refusing to recognize it. Poking around in my bios has only gotten me as far as into loading into the SystemD boot menu, but no win10 boot in sight.

Now before you go mentioning balena etcher, you should note that it is not currently supported by the latest version of pop. Is there anything else I could do? As far as I know, all the files are correctly in place on the flash drive!

First you install Windows and then Linux, I don't think the opposite is possible

Most guides see this as the preferable option, especially if both operating systems are put on separate hard drives. Windows 10 Detects SystemDboot's efi partition and put its' efi files there.
