About UEFI

UEFI Boot has finally been supported by Microsoft in desktop systems. If an operating system can be installed on a GPT hard drive, then it means this very computer supports UEFI Boot. To tell if the operating system has been installed on a GPT hard drive successfully or not, we can use Windows Disk Management to identify.

Open the Run dialog box with the shortcut Win + R, and type in "diskmgmt.msc" and press Enter to open Disk Management in Windows 10/8/7. Then right click on the system disk.

Convert to MBR

If we can find "Convert to MBR Disk" option available in the menu list, then the system has been installed on the GPT disk already, which also means this computer supports UEFI Boot. However, if the computer does not support UEFI Boot, we will see "Convert to GPT disk" in the drop-down menu instead. Also, many disk partition tools mark GPT or MBR disk directly.

Nowadays UEFI Boot is supported by both Windows 10/8/8.1 and 64 bit of Windows 7. It also has been widely adopted by laptop manufacturers and Server platform. On the other hand, most of the backup tools now on the market are still not 100% compatible with UEFI Boot while AOMEI Backupper has already realized the perfect support for it.

How to Backup System Drive Based on UEFI Boot?

Creating a system image backup based on UEFI boot is exactly the same as making a backup for system drive base on BIOS Boot, because AOMEI Backupper has full support for UEFI boot system.

How to Restore System Drive Based on UEFI Boot?

You can try following steps to restore a system image when the need ever arises in the future.

The First Case: Restore System Directly

If your system support for creating a Windows Preinstall Environment (WinPE) environment, you can directly use AOMEI Backupper to restore system drive, and AOMEI Backupper will prompt you to restart the computer and enter into Restart Mode to complete the restore operation.

The Second Case: Restore System Image with Bootable Media

If your system environment does not support creating Windows PE environment, your computer will not be able to enter Restart Mode. Therefore, you need to use AOMEI Backupper to create a Windows PE bootable media first, and then restore system from that bootable media. During creation, AOMEI Backupper will download a Windows PE environment online. As a result, make sure your computer is Internet connected.

Part 1. Create Windows PE Bootable Media

Here comes detailed steps of creating Windows PE bootable USB drive via AOMEI Backupper:

Step 1. Launch AOMEI Backupper. Go Home > Tools > Create Bootable Media.

Create Bootable Media

Step 2. At "Bootable Disc Type", select the "Windows PE" option.

Part 2. Restore System Drive with Bootable Media

Step 1. Restart your PC and keep tapping Del (or F12 or F2) to enter BIOS. Then change boot priority to the bootable USB drive.

Step 2. You'll see a loaded AOMEI Backupper at the desktop. Click Restore button on the left side and select the system backup image by clicking on "Select Image File". Then follow the instructions to complete the system restore process.

Select Image File Winpe

Note: Please make sure your system image can be accessed from the Windows PE environment.

Alternate Way: For computers that does not support creating Windows PE environment, you can also download tools from Microsoft Official Website. Download Windows AIK for Windows 7 and Windows ADK for Windows 10.


UEFI or EFI boot mode is more and more popluar among computers. It is very important for us to know how to perform an UEFI restore. More importantly, to foster a habit of regular data backup as well as system backup with reliable backup software.
