What is EFI Partition?
EFI system partition (ESP) is a partition found on a storage device such as hard drive, the files of which are used by UEFI (Unified Extensible Firmware Interface) to start different utilities, as well as the installed operating system i.e Windows. EFI stands for Extensible Firmware Interface. EFI partition creates various sections on the hard disk of your computer. The information stored in these different sections are normally managed on a separate basis by Windows OS. EFI partition contains four major parts including device drivers, data files, boot loaders, and system utilities.
What Will Happen if EFI Partition is Missing?
As mentioned above, EFI partition is quite useful to Windows systems, especially those that use the Unified Extensive Firmware Interface (UEFI). Now, if the EFI partition is missing, there will be a problem with your system booting. While the boot loader (UEFI in this case) is tasked with loading all the necessary utilities and files before the booting sequence is complete, the ESP resolves any errors that could prevent the booting from being a success. In a nutshell, if EFI partition goes missing, your Windows will be unable to boot.
Restore EFI Partition in Windows 10 via Command Prompt
To restore or create EFI partition in Windows 10 using Command Prompt, follow these steps:
- Use your Windows 10 installation or bootable media to boot your PC since your PC is unbootable on its.
- When the computer is on the first screen, press these keys on your keyboard: “Shift” and “F10”, altogether. This shortcut will lead you to the “Command Prompt” window
- In the window, type in these commands, remembering to press the “Enter” key after you type each command:
select disk # (choose the location where you initially deleted the EFI partition from, for instance)
create partition efi size=260
format quick fs=fat32
list volume (input the volume letter where your Windows has been installed)
Continue by inputting the following too, with “Enter” taking you to the next command:
bcdboot c:\windows (where “c” is the volume letter of the Windows partition)
- Remove the installation media of Windows from the computer and reboot it.
Restore EFI Partition through Clean Installing Windows 10
Another method with which you can restore EFI system partition is via clean installing Windows 10 altogether. The steps involved are:
- Create an installation media for Windows
- Change your BIOS boot order to “Removable device” if you are using a USB.
- If you are using DVD/CD, then change the order to start with “CD-DVD Drive”
Exit the window by clicking “Yes”, having agreed to save the changes made
- Restart your computer and insert the installation media into it to begin the clean installation. Choose the keyboard input, your choice of language, currency and time formats. To continue, click “Next”
- Tap the “Install now” button
- Read the license terms and tick to agree to them, then move to the far bottom right of the window and select “Next”
- Choose the option “Custom: Install Windows only”. Note that all your files will be deleted in this process so if you wish, use the bootable media to backup all your files first.
- Choose to completely delete both system and primary partitions to have a completely clean Windows install. This is instead of formatting these partitions
- Choose the space that has not been allocated and select “New” to create a new partition.
- Follow the instructions for creating new partition till Windows set up and restart.
The Bottom Line
You can restore lost EFI partition through Command Prompt or via a Windows 10 clean installation. Both methods are quite effective so either one you choose is fine. If you cannot boot your computer because the EFI partition is broken, Recoverit Data Recovery can restore back your system files and data.
