Recently a Prestigio smartbook had to be reinstalled with latest Windows 10 1803. This laptop came with 32 bit Windows but had 64bit CPU. So I [wrongly] assumed 64-bit Windows would work. That was not the case!

I’d made 64-bit Windows 10 installation USB stick using Rufus (MBR:UEFI). But when booting I’ve received an error:

[FAIL] Could not locate '/efi/boot/bootia32.efi': [14] Not Found

The reason for that seems to be the cheaper hardware – the CPU was 64-bit, but the UEFI implementation was 32-bit…

Unlike in Linux, for Windows OS there’s one very simple solution: just make 32-bit Windows installation USB stick. Works like a charm!
