Create/recover EFI partition on Windows 11
Having a computer with no boot partition can prevent your system from rebooting, as there is nothing to boot from. In a case like this, you will need to create a EFI (Extensible Firmware Interface) system partition through your Windows 11 device. Alternatively, recovering an existing EFI partition on your Windows 11 PC is possible by using a third-party recovery software that can save time and energy.
An EFI system partition is necessary since it allows the Windows 11 operating system to boot up through the internal hard drive that is already installed on your PC. The only time an EFI partition is not necessary to boot from the main drive is when there is an external hard drive that is being used to boot up instead of an internal hard drive. For that reason, if you are using an EFI boot partition on your PC and if it is accidently removed, you can follow our step-by-step process to recover the deleted boot partition or you can create the same EFI boot partition through a manual process.
What will happen if Windows 11 boot partition is missing?
If you are having issues with your Windows 11 computer, and have attempted to fix the system without success, you will need to use the recovery options to recover the deleted partition. Users can either do this manually or use a third-party software that will take care of this for you.
Follow these steps to recover a deleted partition.
Step 1. Go to the Start menu and type "Command Prompt" into the search bar.
Step 2. In the open "Command Prompt" box, type in "bootrec /fixmbr" to repair the Master Boot Record in case it has been corrupted or damaged, then hit the "Enter" key.
Step 3. You will then need to type two more commands hitting the "Enter" key after each. The commands are:
Step 4. You can now Reboot your PC and the deleted partition should be restored to its original format.
