I have a Hyper-V VM (generation 1) booting from iSCSI
The OS in the iSCSI target is Windows 10
it loads almost all of the of the system
and fails at end with "INACCESSIBLE_BOOT_DEVICE" error
try with 32 and 64 bit Windows10 but no candy...
Googled everywhere and no candy also...
When I boot the VHDX in a VM it works fine
so the Hyper-V drivers must be there (NIC/Storage/...)
