I'm running Kubuntu 20.04, and I'm trying to create a USB stick for installing Windows. I have the Windows image I need to put on the stick -- no problem there. But I've been thwarted at every turn.
My first thought was to use Startup Disk Creator, but that only works for Linux images. Next I tried Woeusb, but it's no longer maintained and I couldn't get it to run. So I turned to Unetbootin, but I couldn't get it to accept my USB drive. I tried it with a single FAT partition on the USB drive (what could be more vanilla?), both empty and nonempty. I also tried using gparted to fix the USB drive, but it wouldn't recognize the USB drive either. So I'm out of ideas.
