On market, the only systems known to ship with IA32 (U)EFI are some old Intel Macs (pre-2010 models?) and Intel Atom System-on-Chip (Clover trail and Bay Trail) Windows Tablets, which boot ONLY in IA32 UEFI mode and ONLY from GPT disk. They do not support x86_64 UEFI boot from GPT/MBR disk, x86_64 UEFI boot from MBR disk, or BIOS boot from GPT disk.


A good example of this is Windows 11 which still works on a BIOS/MBR configuration once the Windows Setup check is bypassed.

Note: The following points only list configurations supported by the Windows Setup even though Windows itself may still work on these unsupported configurations.
