“BIOS finds the disk; BCD boots Windows” compresses several different responsibilities. PVE’s virtual-device order, UEFI boot entries, and Windows BCD system selection are separate configurations.
On September 21, 2026, I fully cloned a Windows Server template into VM202, disconnected its network, disabled autostart, inspected it read-only, and observed a normal boot. Template VM200 and DC VM201 were untouched. This was static evidence plus boot verification, without firmware execution tracing or ETW boot timing.
