How to Recover BitLocker

A step-by-step guide to recovering BitLocker with a recovery key

Author Info

Last Updated: August 23, 2024 Tested

BitLocker, as a drive encryption service, occasionally experiences lockouts. These result from changing BIOS/UEFI settings, replacing hardware components, malfunctioning hardware, forgetting your BitLocker password, or entering your password incorrectly too many times. Luckily, there is a way to recover BitLocker, if you have the recovery key.^{[1]

Finding the Recovery Key

Download Article

1
Search for a copy online. Go to onedrive.live.com/recoverykey and find your PC name and the recovery key.
- If you already have your recovery key, jump to our section about entering the recovery key.
2
Search for a copy on a USB drive. The USB drive should be in a safe place so that you can recover BitLocker. Plug the drive in when prompted to enter your recovery key to unlock your drive.
- If you have the key saved as a text file, you must manually open the file on a separate computer to see the recovery key.

This should be stored in a safe location, so that no one can access the key and your data.

Wait for the recovery screen to pop up.
The recovery key is 25 to 48 characters long with dashes every five characters, so check that you have not mistyped the recovery key.

Press "Enter" or click "Next" to proceed. If the recovery key is incorrect, then ensure that you did not mistype the recovery key and try again.
- If your recovery key doesn't work no matter what, jump ahead to learn how to reset your PC.

Resetting your PC

Find the recovery key first. Note that resetting your PC will erase all data on your computer.
4
Click on "Restore factory settings" or "Recover from the cloud". Unfortunately, you are unable to reinstall Windows by clicking on "Reset my PC" or "Refresh my PC". Instead, you will get locked into BitLocker Recovery.
- Alternatively, reinstall Windows using an installation disc.
6
Wait for re-installation. Your PC will reinstall Windows through the following process:
- First, your PC will download the Windows installer (if there is not one built into Windows RE).
- Then, your PC will run the Windows installer. The installer will erase your drive and install Windows onto your PC.
- Finally, you will be prompted to complete initial setup, which should not be so hard, especially because Cortana guides you through setup on the Windows 10 Fall Creators Update (version 1709) and later.

Question

I encrypted a USB drive with BitLocker but I closed out BitLocker while it was encrypting. Now how do I recover my password?

Unfortunately, BitLocker uses industry-standard encryption, meaning that it is unlikely you will be able to recover the contents of that drive. If you forgot the recovery key, you will have to wipe the drive clean.

Question

How do I enter the characters in my recovery key?

Aasim

Top Answerer

Use a keyboard to do this. If you do not have a keyboard but have a touchscreen, tap the keyboard button in the corner. Due to software limitations, most Windows recovery screens use the US English keyboard layout, so if you have a different keyboard layout, you should search online to see which keys map to which characters. For example, the "ñ" key maps to ";" and QWERTZ and AZERTY map to QWERTY.

Question

I don't have a BitLocker recovery key stored in my email account. What can I do?

Aasim

Top Answerer

You can search for a paper copy, or you can search for a USB drive you backed the recovery key up to. Unfortunately, if you do not have the recovery key, you will not be able to break the AES-128 or AES-256 bit encryption without the recovery key.

Some machines will refuse to even reinstall Windows without first decrypting the drive to protect against theft.
