[Bug 2078307] Re: Grub 2.12 in Oracular is unable to boot Windows using chainloader

[Mate Kukri]

Hmm that looks extremely weird. It seems like GRUB is deciding to
enforce NX policy on your machine despite it clearly booting from the
shim that is requesting it not to...

One hunch I have is that maybe shim doesn't export MokPolicy with UEFI
Secure Boot disabled, and we accidentally always enforce NX when UEFI
Secure Boot is off.

Maybe can you try enabling UEFI Secure Boot in your UEFI configuration?
(it's sometimes called Secure Boot mode "Windows UEFI mode" instead of
"other os")
