Если кому интересно то вот ответ разработчиков:
Well, after some discussion with developers it seems that it's just possible that your HP hardware is unsupported. The problem probably does not involve the difference between 32-bit and 64-bit image. It's just possible that your HW requires UEFI boot, which is unsupported by Control. You should check boot settings if there's switch from UEFI to legacy BIOS booting. Anyway, the performance benefit of running Control on bare HP 830011-B21 would not be high. If you overcome the booting issue, you may face other ones (e.g. that only one CPU core is used). I would highly recommend to use virtualization on your hardware.
You can try to install current 64-bit Debian using its ISO image. If it works, it *might* be possible to fix the booting issue in Control. Please let us know if you manage to install Debian on your system.
