Title:
  GRUB2 fails to launch Windows 10 in dual boot setup

Status in grub2 package in Ubuntu:
  Confirmed

Bug description:
  After upgrading to Kubuntu 24.10, or after a fresh install of Kubuntu
  24.10 (including after a fresh install of Windows 10), GRUB2 is no
  longer able to launch the Windows 10 entry, failing with "error:
  cannot load image".

  To reproduce:

  Install Windows 10 with Secure Boot enabled (or get a machine with an existing Windows 10 installation)
  Install Kubuntu 24.10
  Reboot
  Select the Windows option in the GRUB2 boot loader.

  Expected behaviour:

  Windows 10 is launched successfully.

  Actual behaviour

  Get a message "Error: cannot load image", then a message saying "Press
  any key to continue". At this point GRUB2 is in some kind of corrupted
  state and can't launch ANY of the items successfully, necessitating a
  restart of the machine.
