[Bug 1839317] Re: Grub fails to chainload the Windows Boot Manager on aarch64 laptops

[Daniel Ferradal]

To answer my own comment #23.

I managed to work around this like this:
* Forcing Windows 10 to use \EFI\ubuntu\shimx64.efi as in "bcdedit /set {bootmgr} path \EFI\ubuntu\shimx64.efi"
* Changing BIOS setup to use Secure Boot (Didn't have it, didn't want it. never had it).

Not both ubuntu and windows 10 boot correctly when grub menu shows up.

Title:
  Grub fails to chainload the Windows Boot Manager on aarch64 laptops

Status in grub2 package in Ubuntu:
  Confirmed

Bug description:
  After an update to 2.04 Grub fails to chainload into Windows.

  When selecting the menu item to boot into the Windows Boot Manager,
  the menu flashes and returns.

  When trying to chainload/boot via the Grub command line, nothing
  happens and the prompt reappears.

  When using the same commands in an earlier version (on a bootable USB
  stick) Windows sparks into life.
