To repeat or rather summarize my findings described at length in my post.
Windows has this Lightweigth Filter Driver that is a core component to the windows system.
It only has a blacklist, and you can only block known and already bound Nics. Since windwos10, it is a bit more resilient to actual changes of the network card itself, but if the system changes enough that the boot-nic is detected as a new and non blacklisted device, the driver will bind to it, and will then cause the “inaccassable_boot_device” bsod.
The currently known way of fixing it, is getting the targetsystem too boot once, probably from an ssd, hdd, or what ever, then have it detect the hardware, go in and blacklist the boot-nic, and then image it back to the iscsiTarget.
Possible options i have thought about are:
Killing the driver completely, which doesn’t seem possible.
Have code run in the kernel on boot, that automatically blacklists all the nics. Which seems to be the most realistic option to me currently.
