Surface Laptop 6 for Business

[jarett]

Having issues with the Surface Laptop 6 for Business. I've had two come through, 13.5 and 15" models and they both don't seem to want to launch any images. They sit on Preparing for boot.. please wait. They never get any further. I'm wondering if/how to troubleshoot. Also the Surface Pro 9 does not boot, sits on Preparing.. it's something to do with the new Surface range of devices. Does it have something to do with the Unsupported Window Size 4 error in the log? I can PXE boot just happily on most everything else. These are using Surface Docks to pxe boot from.

I eventually got it to PXE boot using Server 2022 ISO but I think the problem here is the wacky resolutions of the Surface Devices, The Laptop 4 13.5 inch model comes with a 2256 x 1504 resolution and the 15 inch model comes with a 2496 x 1664 resolution. It doesn't matter which resolution that gets switched to for the Windows PXE boot, it's a garbled mess.
