How to erase BitLocker encrypted drive on Windows

On Windows 11 (or 10), you can enable BitLocker (or Device Encryption) to protect your files using data encryption to prevent unauthorized access.

If you must erase a drive using encryption with BitLocker, you can use GParted, a Linux-based tool to manage partitions that allows you to delete and format any drive regardless of whether it’s using encryption.

In this guide, I will teach you the steps to wipe a drive when you can’t turn off encryption that has a Windows 10 or Windows 11 installation.

Warning: These instructions 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.

Wipe out a drive encrypted with BitLocker using GParted

If you still can’t erase the BitLocker encrypted drive, you will have to download and create a bootable GParted USB.

Create a GParted bootable USB

To create a GParted bootable media, connect a USB flash drive with at least 2GB of space to a different device and use these steps:

Download tuxboot from SourceForge.

Quick note: Although the tool hasn’t been updated in quite some time, it still works to create bootable media on Windows 11 or 10.
Double-click the tuxboot-x.x.x.exe file.
Click the Yes button to bypass the “unknown publisher” warning.
Select the On-Line Distribution option.
Choose the gparted-live-stable option.
Select the USB Drive option in the “Type” setting.
Choose the USB flash drive form the “Drive” setting.

Once you complete the steps, tuxboot will create a USB bootable media with GParted, which you can use to boot your computer and wipe out the encrypted drive in question.

Format drive with BitLocker with GParted

To use GParted to delete a drive using BitLocker, connect the USB flash drive with GParted to your device, and then use these steps:

Quick tip: You’ll need to change your device BIOS settings to start using the bootable media. This process usually requires pressing one of the function keys (F1, F2, F3, F10, or F12), the ESC, or the Delete key. For more specific instructions, check your PC manufacturer’s support website.

Start your computer with the GParted USB drive.
Select the GParted Live (Default settings) option and press Enter.

Start GParted
Select the “Don’t touch keymap” option and press Enter.
