How to know if my computer is using EFI/UEFI or BIOS firmware interface

APPLIES TO:
  • Parallels Desktop 9 for Mac
  • Parallels Desktop 8 for Mac

Symptoms

You are not able to migrate your Windows 8 or Windows 7 PC into a Virtual Machine using Parallels Transporter. Migration fails on detecting the Operating System type.

Cause

Most probably your PC has GPT partition on the hard drive and is using EFI/UEFI instead of BIOS.

Resolution

Parallels Desktop currently does not support migrating computers with GPT partitions and EFI/UEFI.

To determine whether your PC is using BIOS or EFI/UEFI please follow the steps below:

  1. Start your PC
  2. Go to Start ► Computer

  3. Navigate to C:\Windows\Panther\setupact.log

  4. Open setupact.log

  5. search for this string:

    Callback_BootEnvironmentDetect: Detected boot environment:
    

    It should tell us the boot environment: BIOS or UEFI:

    Code:Callback_BootEnvironmentDetect: Detected boot environment: BIOS
    Code:Callback_BootEnvironmentDetect: Detected boot environment: UEFI
