Does the 32-bit version of Windows 10 not support UEFI boot installation?
Attempting to install Windows 10 32-bit (including versions 1803 and LTSC) on a Gigabyte H61M-SP2 motherboard. The motherboard recognizes and selects the UEFI mode USB drive for booting, but fails to enter the installation interface. It directly displays the message “reboot and select proper boot device,” indicating that no boot device can be found. Does this mean that 32-bit systems do not support UEFI installation? How should it be configured correctly?

If your motherboard's firmware is UEFI-only and doesn't have a Compatibility Support Module (CSM) or legacy BIOS mode enabled, installing 32-bit Windows in UEFI mode might be problematic.
Yes. You need to switch to UEFI boot in BIOS.
Most modern UEFI firmware is designed primarily for 64-bit operating systems. 32-bit Windows installations typically do not support UEFI boot mode on most hardware, especially older motherboards like the Gigabyte H61M-SP2.
