I know there are some guides out there for linux to do secure UEFI boot via a shim and then bootstrap some other OS. Has anyone done this to boot a version of Windows that is incompatible with UEFI?
Windows 7 x86 should be compatible with UEFI, unless it is a 64-bit only UEFI…
32-Bit UEFI was rarely supported, afaik.
In 2011-2014, I've seen many Nettop systems with a 32-Bit processor and a 32-Bit UEFI.
And even if the processor was technically 64-Bit capable,
the chipset drivers were available as 32-Bit binaries only.
In essence, that UEFI software was thus reduced to a shiny CMOS Setup Utility with CSM enabled (BIOS payload).
Because, Windows x86 didn't support 32-Bit UEFI and using the old BIOS/CSM was the only way to boot.
That being said, this was 10 years ago.
Not sure if Windows 7 finally gained the ability to run on 32-Bit UEFI.
But back then, MS just didn't bother to support it.
The setup DVD didn't support it, at least.
