Ventoy
THIS WORKED, wow.
- Ideally just use previously-installed Ventoy on the SAM 256GB Ventoy stick. HOPEFULLY you can always just drop a new ISO on that in the partition with all the space, and boot right up with it!
- If you need to install it fresh again, try this.
This stupid thing sets up a boot disk that you can copy a windows ISO to and fall through to boot that. What a horrible mess! But it is the only thing that is working!! WoeUSB was shit too. Sad.
