Where to find Bitlocker password if not found either on AD or on All Devices | Recovery keys

Question

Hallo I have a locked computer and I am not able to find the Bit locker password either from AD or from " All Devices | Recovery keys" on MS Azure. Do we have some other places to find the Bit Locker password. I am trying to reset a computer and would like go to the boot screen but no matter how I start the computer it takes me to the Bit locker screen.

Answer 1

If you are asking about possible locations, where you could save your bitlocker recovery key here are the available options:

https://support.microsoft.com/en-gb/windows/finding-your-bitlocker-recovery-key-in-windows-6b71ad27-0b89-ea08-f143-056f5ab347d6

• In your Microsoft account: Open a web browser on another device. Go to https://account.microsoft.com/devices/recoverykey to find your recovery key.
• On a printout: You may have printed your recovery key when BitLocker was activated.
• On a USB flash drive: Plug the USB flash drive into your locked PC and follow the instructions. If you saved the key as a text file on the flash drive, use a different computer to read the text file.
• In a work or school account: If your device was ever signed into an organization using a work or school email account, your recovery key may be stored in that organization's Azure AD account. You may be able to access it directly or you may need to contact the IT support for that organization to access your recovery key.
• Held by your system administrator: If your device is connected to a domain (usually a work or school device), ask a system administrator for your recovery key.

Answer 2

If that computer was taken in use before Intune and AzureAD, and user registered his own user name, it could mean that he used MS account for Windows installation and during that Bitlocker gone to his MS account.

But, if you are about to reset Windows, it doesn't matter do you have Bitlocker key or not. You could just install it with USB installation media (only thing is that you will loose user and app data, is that ok?)

Answer 3

If you are unable to find the recovery key and can no longer get into windows to create a new one, then you will likely have to reimage the device and will lose data.

If you are going to reinstall Windows from a USB you will need to enter the bios and disable secure boot so you can boot and reimage from USB.

1. Enter the bios with the key that matches.
   1. Acer: F2 or DEL
      1. ASUS: F2 for all PCs, F2 or DEL for motherboards
         1. Dell: F2 or F12
            1. HP: ESC or F10
               1. Lenovo: F2 or Fn + F2
                  1. Lenovo (Desktops): F1
                     1. Lenovo (ThinkPads): Enter + F1.
                        1. MSI: DEL for motherboards and PCs
                           1. Microsoft Surface Tablets: Press and hold volume up button.
                              1. Origin PC: F2
                                 1. Samsung: F2
                                    1. Sony: F1, F2, or F3
                                       1. Toshiba: F2
2. Go through the menus until you find the secure boot setting and disable and save the settings.
3. Locate the correct boot menu hot key from this list and use it to get to the boot menu.

4. Boot from the USB option and reimage the device.
5. Follow reverse steps to reenable secure boot.

Similar steps may be needed if you are going to reimage it will MDT or some other option. You would just boot to network or something instead of the USB key from the boot menu.

Note this will erase all data on the device.
