Prompt for Bitlocker key after uninstalling updates - Windows 10

Hi Joe,

Thank you for writing to Microsoft Community forum.

I understand that it can be difficult when your own computer is inaccessible due to some changes that could have happened. However, let's try a few troubleshooting steps and see if we can access the drive.

• Is the BitLocker Recovery key that you found, valid?
• If yes, what exactly happens when you enter the key?

If it's not a valid key, you may try to locate the BitLocker key on your Microsoft account, which will help you access the drive. Refer
Find my BitLocker recovery key
to know how to find the BitLocker recovery key.

If no recovery key is found, enable the secure boot setting from BIOS and see if you can access the drive.

• Power off the device and then power it on.
• Look for a message on the boot screen just before or after the manufacturer logo appears. You may need to press the
  'F1','F2', or 'Delete' button, whatever key is indicated on the boot screen to enter BIOS Settings.
• Within BIOS, choose the tab 'BOOT'.
  
  (Note: Depending on the BIOS manufacturer this page could be
  BOOT, ADVANCED, STARTUP etc.)
  

• Look for a setting called 'UEFI Secure Boot' and toggle the Secure Boot setting to
  'Enabled'.
  
  (Note: Each BIOS could have a different name for UEFI Secure Boot. These are the keywords to look for:
  'UEFI', 'Secure Boot', 'Legacy Boot'.)
  

Restart the machine now.

Note:

Modifying BIOS/ complementary metal oxide semiconductor (CMOS) settings incorrectly can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems resulting from the configuring of BIOS/CMOS settings
can be solved. Modifications of the settings are at your own risk.

If the key is valid, try the troubleshooting steps listed in

PC prompting for Bitlocker recovery key, cannot find the recovery key

Hello Leckbir,



Thank you for writing to Microsoft Community Forums.



For further clarity on the issue and to guide you accordingly, respond to the questions listed below:

1. Since when are you facing this issue?
   
2. Are you aware of any changes being made to the PC?
   
3. Which version of Windows is installed on the PC?
   
4. What is the make and model of the PC?
   

This issue can be caused if a BIOS/firmware update has been pushed to your PC either through Windows Updates or any other OEM media update.



If you have set up the Bitlocker on your PC, I suggest you to look for the recovery key on your Microsoft account. Also, you can refer the article

Hope it helps.
