The laptop cannot power on. I am on a new laptop. I need the bitlocker for my old laptop.

    Retrieve the 48-digit BitLocker recovery key from the account or backup where it was saved, then connect the old drive to the new laptop and unlock it with the matching key.

    1. Connect the old drive and record its key ID

    1. Remove the HDD or SSD from the powered-off old laptop, or have a repair shop remove it.
    2. Put it in a compatible USB enclosure or adapter and connect it to the new laptop.
    3. In File Explorer → This PC, double-click the old drive.
    4. When BitLocker prompts for the recovery key, record the first eight digits of the recovery key ID. This identifies the correct key if several are listed; it is not the recovery key itself.^1^

    Ensure that the enclosure matches the drive type and connector, such as 2.5-inch SATA or M.2 NVMe. If uncertain, a repair shop can identify it without formatting the drive.

    2. Find the matching 48-digit key

    On the new laptop, check these locations in order:

    1. Personal Microsoft account
      • Open https://aka.ms/myrecoverykey.
      • Sign in with every Microsoft account that may have been used to set up the old laptop.
      • Match the displayed key ID to the first eight digits recorded above.
      • Copy the corresponding 48-digit recovery key.
    2. Another person’s Microsoft account
      • If somebody else originally configured Windows or enabled BitLocker, the key might be stored in that person’s account rather than yours.
    3. Work or school account
      • If the laptop was ever connected to an employer or school, open https://aka.ms/aadrecoverykey, sign in, select Devices, expand the old device, and choose View BitLocker Keys.
      • If the key is unavailable there, contact that organization’s IT department.
    4. Offline backups
      • Check USB flash drives for a recovery-key text file.
      • Search printed records and saved files for a BitLocker recovery-key printout, text file, or PDF.

    These are Microsoft’s documented recovery-key locations.^1^

    3. Unlock and copy the files

    Return to the BitLocker prompt for the old drive, enter the matching 48-digit key, and select Unlock. Once the drive opens, copy the required files to the new laptop or another backup drive.

    Do not format, initialize, reset, or reinstall anything on the old drive; those actions can destroy the files being recovered.

    If no recovery key can be found

    The key cannot be extracted from the old laptop merely because its drive is available, and Microsoft Support cannot retrieve, provide, or recreate a missing BitLocker recovery key. Without the correct key, the encrypted files cannot be accessed.^1^

    A reset or clean installation would erase the drive and remove the existing files, so it is not a recovery option when the goal is to preserve those files.

    I wish I could share good news, but the truth is no one can get you the bitlocker key, including Microsoft staff/support. https://support.microsoft.com/windows/find-your-bitlocker-recovery-key-6b71ad27-0b89-ea08-f143-056f5ab347d6 The link here says:"Important: Microsoft Support doesn't have the ability to retrieve, provide, or recreate a lost BitLocker recovery key."

    Is this where you looked? https://account.microsoft.com/devices/recoverykey

    If you set it up with school or work account, it is worth checking here as well https://aka.ms/aadrecoverykey sign in with your work/school email credential in that case.

    Any chance your laptop was purchased used, or already set up for you? Or was it gifted? Or have you set it up with a different account at first? The key is stored with the very Microsoft account used to set up the computer for the first time, even if you had got rid of that account and set it up with a different account. So, if your computer was set up by anyone at the store you bought it from, it would be that person's account.

    I assume you don't remember opting out of not saving it in Microsoft account, and saving it to a local file instead? That's another possibility.

    If you can't find it at all, there's really no way to go around it. Bitlocker means business. If it can be bypassed, then it means the encryption is not working. Your only option is to do a clean install of Windows. In that case, you do lose your files. I am very sorry.
