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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2078307 Title: Grub 2.12 is unable to boot the Windows system using the chainloader /efi/Microsoft/Boot/bootmgfw.efi.
