Boot from SAN device 0xe0 failed: Error 0x7f222092

[ziferr]

I'm trying to reset around 30 notebooks using iVentoy PXE server I setup and tested with an ISO for debian yesterday, server worked fine. My plan for the notebooks was to create ISOs for every one of them (all identical models and setup with Win11) and reset them all using the same image via PXE boot.

Already created an ISO file with Veeam Backup Agent and put it in the ./iso folder on the iVentoy VM. Lists the isos fine on the client but when I choose the new ISO it just outputs the same error listed above in title.

Any ideas? iVentoy is setup on default ports, using either CLI or GUI won't change anything. Tried resolutions 800x600 and 1920x1080. Also tried all three choices for EFI Boot File in configuration. Is it the image? Is it a problem with Win11?
