If the storage drive containing your operating system does not appear in the boot selection list, the motherboard is not communicating with the drive. Enter the BIOS utility again.

Download the Windows Media Creation Tool on another PC and create a bootable USB drive.

The famous saying among experienced users is true: prevention is better than a firmware cure. Here are some proactive measures you can take to minimize the risk of encountering the EFI Shell error again:

: Refreshes the drive mapping. Use this if you just plugged in a USB drive.

. If you are seeing this screen on your computer, it usually means your system failed to find a bootable operating system (like Windows) or the boot order in your BIOS is incorrect. What is EFI Shell?

The EFI shell version 2.60 5.12 2021 screen is a common sight in modern computing, particularly on bare-metal laptops. It indicates that the system is functioning correctly but cannot find a bootable operating system. By adjusting the boot order in the BIOS or ensuring your installation media is properly configured for GPT/UEFI, you can easily bypass this screen and install your operating system.

Should output something like:

Look for , Storage Configuration , or VMD Setup Menu .

Navigate to > Advanced Options > Command Prompt .

If the system loops back to the shell, the BIOS might be targeting the wrong device.

When you see EFI Shell version 2.60 , it indicates the version specification of the UEFI environment your motherboard uses. The secondary numbers, such as 5.12 and a year like 2021 , typically refer to the specific build version and release date of the firmware code provided by the motherboard manufacturer or independent BIOS vendors (like AMI or Insyde).
