Title:
  Issues with Multibooting

Status in grub2 package in Ubuntu:
  Incomplete

Bug description:
  Multiboot machine with Ubuntu, Fedora & Win 11. After updating Ubuntu to 23.10 beta (grub2 to 2.12~rc1-4ubuntu3) I get 
  1) Win11:  BSOD error code 0xc0000428
  2) Fedora: error: bad shim signature.
             error: you need to load the kernel first
  3) Ubuntu: loads but seems to have some gpu(nvidia) driver issue (not important for this bug)

  I can resolve the Win11 error by turning secure boot on (but not the
  Fedora issue)

  However, changing to boot order to start with Fedora (39 beta) which
  still uses grub 2.06 all of the OS's boot with secure boot off.

  so there is an issue with grub2 2.12

  Please fix
