Windows 10: Can not enable BitLocker on system drive

I am trying to enable BitLocker on my home Windows 10 Pro with dedicated and enabled TPM 2.0 module. However, when I try to enable BitLocker for system drive, I got an exception "Ask system administrator"

:)

 

Windows 10 Bitlocker will not enable on system drive (But will on other drives)

Hi,

Thank you for the update and I apologize for the delay in response.

I would like to inform you that as BitLocker requires memory to encrypt, I would suggest you to check if there is sufficient space in the drive.

I suggest you to disable BitLocker from other drives and then try enabling BitLocker on the system drive followed by other drives.

Let us know if you need further assistance. We will be happy to help.

Thank you.

 

Clone Bitlocker enable drive to SSD

My name is Andre Da Costa; an Independent Consultant, Windows Insider MVP and Windows & Devices for IT MVP. I'm here to help you with your problem.

Heed the advice of the software, you must disable BitLocker before cloning. This is highly recommend if you ever want to get access to the drive.

There is nothing wrong with having to re-enable it after restoring the clone.

Step 1: disable BitLocker.

Step 2: clone drive

Step 3: restore the cloned image to the new drive.

Step 4: Re-Enable BitLocker.

 

BitLocker won't enable on Windows 10 after update on Aug 9

Hi Brenda,

I would be happy to assist you.

Before I assist you I would like to know the information below,

• 
  Do you have a Windows 10 copy of the operating system?
  

I suggest you check whether the Bit locker is ON or OFF using the steps below.

Can you verify if BitLocker is enabled or disabled on your device? You can Enable/disable BitLocker by going to Desktop and follow these steps:

• 
  Swipe Right to Left to bring up the Charm.
  
• 
  Choose Settings.
  
• 
  Choose Control Panel.
  
• 
  Select BitLocker Drive Encryption.
  
• 
  Verify whether BitLocker is on or off on each device.
  

Also I suggest you to enable the WinRE so that you can enter the bit locker key and proceed.

When WinRE is disabled, you cannot enable BitLocker, and you receive an error message that resembles the following.

This PC doesn't support entering a BitLocker recovery password during startup. Ask your administrator to configure Windows Recovery Environment so that you can use BitLocker.

The solution would be to manually enable the windows recovery environment:

• 
  Copying the winre.wim file from c:\windows\system32\recovery\ to a folder on a recovery partition. (The partition need to have a drive letter at this point.)
  
• 
  Set the RE Image path. Example: reagentc /setreimage /path r:\recovery\windowsre
  
• 
  Enable RE with command: reagentc /enable
  
• 
  (You may remove the drive letter for the recovery partition after you have done this.)
  
• 
  Bit locker will be enabled.
  

If the issue still persists, suggest you to post your query on the below link.
