On Windows 10, BitLocker is a great security feature to protect your files using data encryption to prevent unauthorized access. Although it’s a handy feature for laptops and desktop computers, you may come across problems when it comes the time to format drive. For example, when the password and recovery key are unknown, and you can’t pass through even with a Windows 10 Setup bootable drive.

Fortunately, if you must erase a drive and BitLocker is getting on the way, there’s a workaround using a Linux-based utility called GParted, which can help you delete and format any drive regardless if it’s using encryption.

In this guide, you’ll learn the steps to wipe a drive when you can’t turn off encryption on Windows 10.

Warning: Using the steps below will delete everything on the selected drive, if you have important data, make sure to back it up before proceeding. Also, GParted and tuxboot are third-party utilities, as such use them at your own risk.
