Before we start troubleshooting, please notice this: Beginning in Windows 8.1, Windows automatically enables BitLocker Device Encryption on devices that support Modern Standby. With Windows 11 and Windows 10, Microsoft offers BitLocker Device Encryption support on a much broader range of devices, including those that are Modern Standby, and devices that run Windows 10 Home edition or Windows 11. Unlike a standard BitLocker implementation, BitLocker device encryption is enabled automatically so that the device is always protected. The following list outlines how this happens: Microsoft recommends that BitLocker Device Encryption be enabled on any systems that support it, but the automatic BitLocker Device Encryption process can be prevented by changing the following registry setting: From Overview of BitLocker Device Encryption in Windows Usefull troubleshooting to bypass the Bitlocker screen so you can disable (not recommended by Microsoft) the same inside Windows: Load BIOS defaults Ultimately, if none of the above steps work, an OS reinstallation would be the final recommendation.

Hi all, I have an unusual problem. 3 days ago my hard drive got blocker by BitLocker. It asks for a key in order to unlock my hard drive. The problem is that I have never installed or set up BitLocker. This is a new laptop and no one had access to it except me. So I am 100% sure that BitLocker was never set up. I bought it via Amazon in Boston 4 months ago. I checked my Microsoft account but didn't find BitLocker key there (again, because I didn't set it up). I called Dell and they told me I should call Microsoft. I called Microsoft and they told me I should call Dell. It's a closed circle and no one seems to be responsible. My solution is to re-install Windows but in this case, I will lose all my data (which I don't want to do). Does Dell community has any recommendations? Did this issue happen in the past? Who could have set up BitLocker encryption on my laptop without providing me with a password? If I don't recover my data, I consider suing Dell here in Boston.
