If you don’t know how to create EFI partition on Windows 11, you’ll find answers after reading the article.
An EFI partition, which stands for extensive firmware interface partition, a special type of partition, is treated as a key component of a computer system boot used to store boot information that is necessary for booting a computer.
Thus, having a computer with no boot partition will prevent your system from rebooting, as there is nothing to boot from. If you are stuck in such a situation, you need to create a new or recover a deleted EFI system partition in order to operate your system successfully.
Hard drive failure: If the hard drive is physically damaged or has bad sectors, the data in the EFI partition may be affected and even the partition itself may disappear.
Malware infection: Some malware may target the EFI partition and cause it to become corrupted or disappear. The situation usually requires the use of professional antivirus software for repair.
Operating system installation or upgrades: If you install or reinstall your system, the hard drive including the EFI partition will be deleted or overwritten. Thus, it’s important for you to think about backing up your important data.
Human misoperation: It happens when the users delete the EFI partition or modify it with the wrong tool.
In conclusion, keeping your hard drive in a healthy state and recognizing backup is the best measure for you to keep your EFI partition correctly.
