Not sure if this is the right place, I'll give it a try. I tried to build and boot a Windows 11 for ARM64 USB stick with rufus, this worked - sort of. What didn't work was booting from this stick on wdk2023, crashed with a Synchronous Exception.

What worked was to format the same stick with exFAT, make it bootable with UEFI:NTFS, copy over all files from the image to the exFAT partition of the stick, boot.

Which is fascinating and great, but apparrently there is an issue with ntfs in this constellation. What can I do to provide some more debugging info?
