On opening my laptop it went to a blue screen called bitLocker.

I have tried all the options including resetting etc. All to no avail.

How can I recover from this?

    If your drive is encrypted with Bitlocker, the only place the Bitlocker Recovery key is automatically stored is on the associated Microsoft account on the link below, be sure to check any Microsoft account that may have been used on the PC and also any work or school account that may be linked to the PC.

    (Note, even if your device does not show on the Microsoft account, the Bitlocker Recovery Key may still be available on this link)

    https://account.microsoft.com/devices/recoverykey

    Are you able to find the Bitlocker Recovery Key on any account that may have been used or linked to the laptop?

    If not, do you have a safe backup of your files, or use a cloud service like OneDrive to sync your files online.

    If you are unable to find the Bitlocker Recovery Key on any account that may have been used on that device, then I am sorry for the bad news, a Windows reset will not work on an encrypted drive, the only way to access that device is to create a bootable Windows 11 USB on another working PC and use that to clean install Windows and at the start of the installation, delete all partitions on the drive to remove the encryption, which will sadly result in loss of all data on the drive.

    Recover the 48-digit BitLocker recovery key first; Windows recovery and reset operations generally cannot access the encrypted drive without it, and reinstalling Windows without recovering the key will sacrifice access to the existing files.

    1. Find and enter the correct recovery key

    1. On the BitLocker screen, write down the first eight digits of the Recovery Key ID.
    2. On another phone or computer, open the Microsoft account recovery-key page:
    3. Sign in with the account used when the laptop was configured.
    4. Match the Key ID on the laptop with the listed key, then enter the corresponding 48-digit recovery key.
    5. If no key appears, also check:
      • Another person’s Microsoft account if that person originally configured the laptop.
      • A printed copy.
      • A USB drive or saved text file.
      • Your employer’s or school’s IT department if the device was ever managed by them.

    These are Microsoft’s supported recovery-key locations. On Windows 11 version 24H2, the recovery screen might also show a hint identifying the associated Microsoft account. Microsoft Support cannot retrieve or recreate a missing key.^1^

    2. What happens after entering the key determines the next action

    • Windows starts: Immediately back up important files and save another copy of the recovery key.
    • The key is rejected: Check that its Key ID matches the ID displayed on this laptop. A different BitLocker key will not unlock this drive.
    • The key is accepted, but the laptop returns to BitLocker or Automatic Repair: This indicates that the drive was unlocked but Windows still cannot start. Since the built-in recovery and reset choices have already failed, do not repeat them. Proceed to the installation-media fallback below.
    • No recovery key can be found: There is no supported way to decrypt and recover the files. Resetting or reinstalling can make the laptop usable again, but it removes the inaccessible encrypted data.^1^

    3. Last resort: reinstall from external recovery media

    This is destructive: reinstalling from installation media removes the existing files, applications, and settings.

    Because the Reset option has already failed, use another working computer to:

    1. Obtain Windows 11 installation media from Microsoft’s Download Windows 11 page, or obtain model-specific recovery media from the laptop manufacturer.
    2. Create a bootable USB drive. Copy anything important off that USB first because creating the installation media formats it.
    3. Connect the USB to the affected laptop.
    4. Open its boot menu or UEFI/BIOS during startup and select the USB device. The required key varies by manufacturer and may be F2, F10, F12, Esc, or Delete.
    5. Reinstall Windows from the USB.

    Microsoft recommends manufacturer recovery media when available because it can include the laptop’s hardware-specific drivers and factory software. A Windows installation-media reinstall is the final recovery option when the computer cannot start, and it removes everything from the device.^2^

    If the files are important, do not reinstall or format the drive until every possible Microsoft, work/school, printed, and USB recovery-key location has been checked.
