Can't locate the bitlocker key

Hi Chris,

Thank you for writing to Microsoft community forums.

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.

• Are you aware of any changes that happened on the computer prior to this issue?
  
• Did you setup a BitLocker on your device before?
  

If you’ve not setup the BitLocker and it’s still prompting for the 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, you may enable the secure boot setting from BIOS and check if you can access the drive. Follow the steps listed below to enable
secure boot.

• 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 to see if you can access the drive.
  

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 you still can’t access the drive, I suggest you to post your query in the

TechNet forums. Our support professionals, equipped with knowledge on BitLocker, will help you further.
