[Bug 2078307] Re: Grub 2.12 is unable to boot the Windows system using the chainloader /efi/Microsoft/Boot/bootmgfw.efi.

[haobinnan]

I am using the shim from https://github.com/rhboot/shim/releases/download/15.8/shim-15.8.tar.bz2, not the Ubuntu shim.

I believe the NX is enabled by default in shim version 15.8.

I have tried booting both Windows 10 and Windows 11, but neither worked.

Regarding "64-bit Linux kernel on 32-bit UEFI," I think the grub2.12
code has implemented some special restrictions. There are indeed use
cases for this, and grub2.06 doesn't have this issue. It seems that
grub2.12 does have this problem.
