Many lightweight laptops (Intel Atom, Celeron, early AMD APUs) use 32-bit UEFI firmware. A 64-bit PE will refuse to boot on these devices. The x86 version boots seamlessly on 32-bit UEFI, 64-bit UEFI (with CSM), and legacy BIOS.

The hbcdpex86iso project — an x86-architecture HBCD (Hiren’s BootCD–style) rescue/live utility ISO — has received an update that refreshes included tools, improves hardware compatibility, and streamlines the build process to produce a smaller, faster, and more reliable rescue image. of Hiren's BootCD currently under development
The project maintainers have shared a roadmap (source: GitHub Discussions, November 2024):
