Follow-up Comment #1, bug #51226 (project grub): I'm facing the same problem, but I get "BlInitializeLibrary failed 0xc0000017" instead of "BlInitializeLibrary failed 0xc0000001".
Some more information from my side: I used 2.02~beta2-9 [1] from Ubuntu long time, which worked correctly. Then, I faced an issue [2] on some physical devices which caused very long boot times. That's why, I switched to a newer build 2.04 from Ubuntu [3]. This version boots my Linux systems fast on the problematic physical devices, but brings up the BlInitializeLibrary failed error when trying to chainload the Windows bootloader (on all devices, VMs and physical).
