bitlocked after theft then wiped bitlock now stuck on no bootable black screen

It seems that your Lenovo Ideapad 3 is experiencing issues due to BitLocker encryption and possibly a device lockout after being wiped. Since you mentioned that the device is now stuck on a black screen with no bootable options, here are a few steps you can consider:

1. Recovery Method: Since the device is locked out, you will need to use a BitLocker recovery method to unlock it. This typically involves entering a recovery key or password that was set up when BitLocker was enabled.
2. Check for Recovery Key: If you had saved the BitLocker recovery key to a USB drive, printed it, or stored it in your Microsoft account, you will need to retrieve it to unlock the device. You can access recovery keys stored in Microsoft Entra ID by visiting https://myaccount.microsoft.com and navigating to the Devices tab.
3. Attempt to Restore Boot Configuration: If the BitLocker was wiped and the device is still not booting, you may need to restore the Boot Configuration Database (BCD). This can sometimes resolve boot issues caused by changes in the boot configuration.
4. Use Recovery Media: If you have a Windows installation media (USB or DVD), you can try booting from it and using the recovery options to repair the startup or restore the system.
5. Contact Support: If none of the above steps work, it may be necessary to contact Lenovo support or a professional technician for further assistance, as they may have specific tools or methods to help recover your device.

Make sure to have any relevant information about your device and the situation ready when seeking help.
