[Bug 1917565] Re: Windows 10 fails with "Boot device inaccessible"

[Nick]

I haven't tried a new install. Also, Michael asked to check 
 git://git.kernel.org/pub/scm/virt/kvm/mst/qemu.git tags/for_upstream
The code in question is changed there and it works fine for that existing image.

Title:
  Windows 10 fails with "Boot device inaccessible"

Status in QEMU:
  New

Bug description:
  The issue is happening on all versions I tried after the following
  commit. I can also remove this individual change from master and it
  starts to work.

  OVMF_CODE.fd is what comes with Ubuntu 20.04 through package manager.
