Whoever solves this Microsoft certificate puzzle, please come forward !!!


Which SkuSiPolicy file did you delete? From the EFI volume on the first or second disk? If you made a second disk with its own EFI volume, that is a different copy of SkuSiPolicy than the first one.

If you picked a specific boot manager or specific boot device, then the EFI volume that belongs to that one has the SkuSiPolicy that is enforced.

EFI volume:
- Must have a bootmgfw.efi​
- Can have a SkuSiPolicy.p7b in same folder​

SKUSiPolicy file which I deleted was in the EFI partition of nonbooting Windows. Its EFI partition size is 200 MB and is easily identifiable. Working Windows EFI partition size is 260 MB.

Then I used Rufus v4.14. This was able to format and create the USB drive with CA2023 and SKUSiPolicy. CA2023 and SKUSiPolicy options came checked by default.
Have you tried it with SkuSiPolicy unchecked?

Have you tried it with SkuSiPolicy unchecked?
No. This was a test disk. I never used it to repair Windows or anything.

By the way, this is the directory (below screenshot) from which I deleted SkuSiPolicy file. In this directory I also have bootmgfw.efi file. This bootmgfw.efi I just xcopied to this directory today.

You didn't follow the instructions correctly.

1. From diskpart, you assigned the 104 MB EFI volume to drive letter S. The volume is readable now from S:

2. From "mountvol S: /s", you asked Windows to re-assign S: to your active EFI volume. Don't use "mountvol /S" for the other volume.

mountvol
/s Mounts the EFI system partition on the specified drive.
