59194: Acronis True Image 2017: How to check if the computer is running 32 or 64-bit UEFI?

Translate to:

Introduction

Almost all modern computers have UEFI (Unified Extensible Firmware Interface) firmware implementations, some of them also including legacy support for BIOS services. UEFI firmware could be either 32 or 64-bit. Not all Acronis programs support both 32- and 64-bit versions of UEFI. See https://kb.acronis.com/content/43091 for 32-bit UEFI devices support limitation.

This article explains how to check whether your computer has 32 or 64-bit UEFI firmware by using Acronis True Image 2017 bootable media.

Solution

  1. Create Acronis Bootable Media with Acronis True Image 2017 in Windows.
  2. Start booting your computer with the created media.
  3. Look at the very first line that appears on the Acronis boot menu screen:

    If it starts with "Starting UEFI Loader(x64)", then your computer has 64-bit UEFI firmware:


    If it states "Starting UEFI Loader(ia32)", then your computer has 32-bit UEFI firmware:


    If you see "Starting Acronis Loader...", briefly changing into a blue boot menu (Acronis True Image-only media) or a colorful menu (a multi-product media containing a combination of Acronis True Image with Acronis Universal Restore and/or Acronis Disk Director, see pictures below), then the media has started in BIOS/CSM mode instead of UEFI:



    It is not possible to determine the UEFI version, if the media has started in BIOS/CSM mode. There are two possible explanations of why the media did not boot in the UEFI mode:
    • you have not chosen the UEFI version of the media in the UEFI boot menu. There may be 2 entries in the boot order list for the same bootable CD/DVD/USB: one with "UEFI" in its title and the other one without "UEFI". Please make sure that you have selected the "UEFI" version,
      or
    • the computer does not have UEFI firmware at all. In that case this KB article does not apply to your computer's firmware.
