Bitlocker: BitLocker could not be enabled

Q: Bitlocker: BitLocker could not be enabled

I am trying to enable BitLocker on a Windows 7 Ultimate x32 system with TPM. I follow the Wizard and when asked to encrypt the drive I select 'Run BitLocker system check' and 'Continue' (see attached sreenshot).
The USB is inserted and contains the recovery key (.txt and .tpm). During reboot I get:

Windows BitLocker Drive Encryption Information
The system boot information has changed since BitLocker was enabled.
You must supply a BitLocker recovery password to start this system.
Confirm that the boot changes to this system are authorized.
If the changes to the boot system are trusted, then disable and re-enable
BitLocker. This will reset BitLocker to use the new boot information.

Otherwise, restore the system boot information.


Windows then continues to start normally. After login I get an error message: BitLocker could not be enabled (see attached screenshot).
When I check TMP it shows as active, initialized and owned.

I've started out from scratch several times - same results. I can't figure out what the problem is.
This is driving me nuts.

Any help appreciated


Preferred Solution: Bitlocker: BitLocker could not be enabled

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A: Bitlocker: BitLocker could not be enabled

DELL: d420
Hard drive: System reserved 100MB NTFS, 27.84GB NTFS

Manufacturer name: BRCM
Manufacturer version: 2.10
Specification version: 1.2
Status: The TPM is on and ownership has been taken

I've since modified the group policy settings for Bitlocker to use a PIN.
I am still getting the same results.
I follow the wizard, select check the system, reboot, enter PIN, get the same "error" messages as shown in my previous post.

This makes no sense.

Any help?

After rebooting one of our test machines, bitlocker wanted the recovery key.
There were no hardware modifications on that machine.
Error message in event log:
Bootmgr failed to obtain the bitlocker volume master key from the TPM because the PCRs did not match
Event id 24635, source bitlocker-driver
 Each time the machine starts, the recovery key is needed.
Any idea how to solve that issue and why it happens?
Second partition was created manually on that machine. So that's clear that bitlocker reacts...
But now: how can I confirm those changes so that the recovery key is not needed each time we boot?

A:Bitlocker enabled drive, recovery key needed during boot, PCS did not match, event id 24635, source bitlocker-driver

I would like to confirm if BitLocker accepts the recovery key?
Please update the BIOS to improve the stability for TPM first.
I also would like to suggest you disable and enable BitLocker again to reset the settings.

I am having trouble getting BitLocker enabled. 

The OS is Windows 7 Enterprise and the computer is a Lenovo L512 ThinkPad. I've updated the BIOS to the latest version.  TPM is on.  There are two partitions - System Reserved - 102 MB - NTFS and C - 232.78 GB that show up in Disk Management.
There are two files on the USB, a .tpm and a BitLocker Recovery Key.
When I click on Run BitLocker system check I'm told to insert the USB memory device containing the recovery key.  I do that and see the message that the computer must be restarted. 
After restarting I receive this message:
BitLocker could not be enabled.  The BitLocker startup key or recovery password cannot be found on the USB device.  Verify that you have the correct USB device, that the USB device is plugged into the computer on an active USB port, restart the
computer, and then try again.  If the problem persists, contact the computer manufacturer for BIOS upgrade instructions.  C: was not encrypted.
I've tried the USB drive in every port on the computer with no luck.
Perhaps there's something minor that I'm missing.  I'd appreciate any assistance.

A:BitLocker could not be enabled.

I figured out my mistake. 
I had set the BIOS boot order to only HD, as I usually do.  I did not realize that USB drive (now the second option in the boot order) needed to be enabled for the encryption process to continue. 
I've tried the encryption process on two computers, and it worked fine after this.
Thanks for the suggestions.

Hi there,

I'm evaluating the 90 day RTM of Windows 8 Enterprise and want to to enable full disk encryption (partitions are stock, c:\ only, didn't create any manually). Unfortunately, Windows won't let me. I own a Dell D630 with built-in v1.2 TPM chip. When starting
the system check (just before the start of the encrypting process) I get the following error message:

Bitlocker could not be enabled 

The Bitlocker encryption key cannot be obtained. Verify that the Trusted Platform Module (TPM) is enabled and ownership has been taken. If this computer does not have a TPM, verify that the USB drive is inserted and available.

C: was not encrypted.

I had a look in tpm.msc and the status displays "The TPM is ready for use". While looking for a solution in the web, I came across several screenshots of tpm.msc where the status was displaying "The TPM is ready
for use and ownership over TPM has been taken". Well this relates pretty well to the error message in the first place. 

Technet (technet.microsoft.com/en-us/library/cc754215.aspx) even has detailled instructions online on taking ownership of your TPM module. Apparently, I need to initialise TPM as per the instructions. The problem is, I don't even
have an initialise option available in the right-hand side action menu of tpm.msc.

Well - I thought - if TPM behaves badly then just disable it and follow these Technet instructions ... Read more

A:Bitlocker could not be enabled (with/without TPM)

This didnt work either, unfortunately... 
However, after deactivating the TPM altogether in BIOS, so that tpm.msc is not even "aware" of an installed TPM chip, I was able to initiate the encrypting process.

It tells you in the error to use the Bitlocker recovery to verify the drive. Was the drive changed by you? di you have a AV current and running?

I am setting up a new X1 Yoga 2nd Gen system and updating to Windows 10 Creator in the process. Somewhere along the line Bitlocker was enabled in the OS. I certainly did not turn it on and I doubt that the Windows Update did either. This system was a preconfigured variant 20JDS0HV00 purchased directly from Lenovo. The BIOS level was updated to 1.20 as well. Is this the norm now? I only realized that the option was turned on when I needed to restore the OS to a previous day and Acronnis complained. I was able to configure it off and decrypted the disk drive. I wonder if the preconfigured system was spec'd to have bitlocker turned on.

A:Bitlocker not getting enabled on Non System drives

Hi Amarjeet and welcome,

Have a look at the default account policy's here, I have a feeling that there's a lock out policy for drives not formatted in Win 7 (or something like that):

Type gpedit.msc to open the group policy manager. Navigate the tree to Local Computer Policy\Computer Configuration\Administrative Templates\Windows Components\BitLocker Drive Encryption\.

Look at both FIXED and Removable drives as I'm not sure how windows differentiates the sata drives.

With the other drives, it's always best to freshly reformat them in windows 7 as NTFS before applying bitlocker encryption. So check this as well.

Let me know if you are successful. Meanwhile I'll try to find a technet article that I read a few months ago with a lot of bitlocker help and post it up for you to read.


EDIT: Here's the link to the technet step-by-step guide.

New to this forum, and this is my first thread. Please provide me with some help if possible.

So my problem is the following: Kept getting BSODs from some driver inflicting with ntkernel according to whocrashed and bluescreenview. Anyways, disabled my network card as I thought that was faulty, updated all my drivers and checked my ram with memtest just to be sure. Was still getting the BSODs.

Decided to use driver verifier to see which driver that caused this. Bad idea. Turns out that one of the drivers indeed was faulty, but now I'm getting blue screen before I can even log in to windows. Tried to boot into safe mood a thousand times by repeatedly pressing F8 and shift+F8 to no avail. Thought that I then could turn of driver verifier from the command prompt, but No! (Since if I could turn this of the BSOD before system start would then stop since the purpose of windows driver verifier is to force the faulty drivers to create BSOD).

Then downloaded EaseUS Recovery Essentials to see if that could help. Turns out that my ENCRYPTED (bitlocker) which my operating system is on, can't be found because I'm assuming that the change in boot order previously when running memtest disabled it.

Now had to find my win8 installation CD to force it into safe mode alternatively to re-install it, but to no avail. It says that the hard-drive is still locked even though I've got the key in a USB stick attached to the computer and even though I manually put in the recovery key. Was now to... Read more

Hi, I'm looking to push out a Group policy that will allow our laptops to have BitLocker enabled - but not require a startup pin while at the sametime use Secure boot. I can currently do this, but only under Legacy. If i enable Secure boot, I get an error
when booting up " Selected boot image did not authenticate" 

Is there anyway to use bitlocker without a PIN and still have secure boot enabled?

With the new major release of Windows 10 AU (Redstone) or even the upcoming Redstone 2 update planned somewhere around beginning of 2017, will I have to temporarily disable BitLocker in the process of updating to Redstone?

Since this is a major update to Windows 10, can it have issues with machines that have BitLocker enabled ?

In any case, I do have backups in place.


A:Updating Win10 to Redstone with BitLocker Enabled?

I have successfully upgraded a major version with bitlocker on. However, that was only because I forgot about it and did not disable it. I would never consciously upgrade like that as the risk is too great in my opinion.

Am super frustrated and would appreciate any help.   ThinkPad X1 6th Gen has been dead more than a week;  OS crashed, but several reboot and repair efforts failed.  Tried system restore.  That required a bitlocker key (which I found online) but then the machine would not accept my account password.  So unable to restore.    Multiple calls with Thinkpad warranty support (hardware and software) could provide no help or guidance.  (Except to send restoration media.)  Mind-boggling lack of support... and no way to escalate issue to someone who actually understood it.  Deeply disappointing experience w/ Lenovo. . So now the question is how -- after I reset my system -- do I avoid this nonsense in the future?   I shouldn't have to rebuild my laptop from scratch anytime there is an OS problem.  BTW, I did not order bitlocker, set up bitlocker or create any password for it.  Do not need it or want it.    Can anyone help with advice on how to set up my machine without it? Thanks.

Getting h/w encryption on my laptop has been a bit of a nightmare, but I thought I had it working.... Here is what I did:

Installed M.2 Samsung 850 evo driveInstalled samsung magician, and set Encryption to Ready to Enable.Removed existing HDDRan samsung secure erase from DVD.Installed Win10Installed Samsung Magician (It said Encryption enabled, finally!)Turned on Bitlocker. It did not prompt me for how much of the drive to encrypt, which (I was told) means that it is using hardware encryption of the drive.Added the HDD back.Updated all my drivers to latest versions for my laptop (Asus GL552VW), including Intel RST drivers (14.x)

After doing all that I just noticed that BitLocker is turned off on my C: drive (the m.2 drive)! I looked in Magician and it still says Encryption is enabled. So I went into Bitlocker to turn it on again for the drive. But now it is prompting me to encrypt used space, or whole disk, which means it isn't using h/w encryption.

What am I doing wrong here? Do I need to enable Secure Boot in BIOS? I have read that the Intel RST drivers can cause problems, but I thought that was only with older versions? Is IRST still an problem?

Edit: When I look in the Disk Management took, I see the C: partition of Disk 1 says: NTFS(Bitlocker Encrypted)., But in Bitlocker Drive Encryption tool it says it is off. Manage-BDE -status c: says that there is no encryption. Really confused now.

There are a list of requirements for hardware based encryption here - doesn't look like secure boot is required: How to Enable BitLocker Hardware Encryption with SSDs Helge Klein

For data drives:
The drive must be in an uninitialized state.
The drive must be in a security inactive state.

If the drive is used as a startup drive the following apply additionally:
The computer must always boot natively from UEFI.
The computer must have the Compatibility Support Module (CSM) disabled in UEFI.
The computer must be UEFI 2.3.1 based and have the EFI_STORAGE_SECURITY_COMMAND_PROTOCOL defined.

I only use bitlocker with software based encryption though so can't add to what they say I'm afraid but some of the comments look interesting.

I received a 2 gb olympus sound recorder which I was asked to restore to normal fuctionality, and restore some mp3s that were presumably recorded on it.

The file system appears to be intact, so I can read from it, but there are two noticeable changes to the device.
First, it seems to have been infected with a version of the RECYCLER virus, which turned all the folders into links which point to the virus itself.
One of those folders are thought to contain the mp3 file in question.
Second, the device seems to have been bitlocker enabled, but it does not need any encryption key.

Now, I don't know, in what order did these events happened; I only need a confirmation, that no data can be recovered once deleted, either before or after bitlocker is enabled.

A:Can deleted files be recovered on a bitlocker enabled device?

there's a chance you can recover the mp3s
you need to rely on professional file recovery tool to get them back. A popular one is Asoftech Recovery. This tool can deep scan your computer and recover your lost files back without requiring extra skills. Here is the steps might be helpful to you:
1. Download this program on your compute. here is the link: Photo Recovery: Restore your lost photo
2. Install and start the program, select the drive where your lost files located, click Start. Now the scanning process will start to search the deleted files. After a while you will then get a list of recoverable files.
3. Press Recover to perform full recovery.
hope this helps..cause the files are infected too.

Title in the subject line pretty much says it.I've got a Dell Precision 5510 and a TB16 dock.It is currently running Windows 10 1703 but this issue existed under Windows 10 1607 as well.
Sequence of events/how to replicate:

Connect the Precision 5510 to the TB16 dock (presence of any other combination of peripherals seems to be irrelevant)
Boot into Windows 10 and enable BitLocker using TPM and a PIN
Shutdown and power on or /restart, whilst still connected to the TB16, enter your PIN and boot successfully
Shutdown and disconnect from the TB16 dock then try to boot - BitLocker prompts for the great big recovery key (what a pain)
Entering the recovery key and proceeding to boot is fine, as is shutting down and trying to boot again with the TB16 attached but if you're away from the office (and the TB16) and don't have the recovery key, then you're in a bit of a pickle!
If you've...

Booted to encounter BitLocker recovery (but luckily had the recovery key with you and entered it)

A:Will BitLocker or BitLocker on the Go ever support CD/DVD encryption?

Bitlocker to Go is not supported on CD/DVD. Your suggestion is valuable, I will forward this information to the appropriate department through our internal channel.
Both the Microsoft Product Team and Development Team will take into consideration all suggestions and feedback for future releases.
Currently, you may need third party software to encrypt CD/DVD.

the control pannel where I should access "Turn off bitlocker", "Security" in the control panel, the settings aren't there.  I've found Bitlocler in the search ba, but can't access any settings except to create a certificate. 
How do I get rid of this program.
[email protected]  (I called microsoft tech support, they transferred me to someone that told me to create an account.  Then told me if I don't subscribe=be to this extra service there's a $400.00 fee for one tine help)!

I see it's suggested to use 2 different USB flash drives when applying Bitlocker.  You need one for the startup key and one for the recovery key.  What size USB flash drive should be used for each key?

Went to the New Efficiency thing today and one of the MS presenters said that the FBI asked MS if there would be a backdoor for Bitlocker. MS said no. According to the MS guy, the FBI then said to MS: you can't include it on 7 consumer versions. Maybe this been discussed here or elsewhere, but that was the first I'd heard the reason why Bitlocker is not on Home or Professional.

In another lifetime I worked for a member of Congress, and one of his big issues was encryption. Congress passed an encryption bill 10-12 years ago? Can't remember, by then I had long left my Congressional job, and I never bothered to read much about what that bill was about. But before it was passed, I do remember the fights between the government and private industry about who should be allowed to use powerful encryption.

My guess is that since the passage of that bill, MS and every other software manufacturer in the U.S. that deals with encryption has to let the Feds know ahead of time what they're working on? Just a guess. I can't imagine it would be the other way around - FBI gets word of something and goes and knocks on Bill Gates's door or whatnot. Then again, having worked in the gigantic pile of crap that is the United States Federal Bureaucracy, I wouldn't be surprised by any federal agency doing anything to anyone about anything at any time.

The only reason I went to the New Efficiency thing was for the free 7. I don't own a business, I command no employees, the closest thing to IT I've ... Read more

Hello, i have just finished building a TaskSequence in SCCM 2012 for de HP Elite X2 1012 G1 notebook.All is working except Bitlocker.All other laptops (HP 650 G1, G2 and Elite X2 1011 G1, etc) bitlocker does work.I receive an error with Active Directory not being setup correcty. Access Denied.This is normally due to de SELF object not able to write the TPM ownerinformation. But our AD has been setup for this a long time ago. And all other laptops etc bitlocker works fine.When i check the bios. all other laptops have an option for OS managament of bitlocker.The new HP Elite X2 1012 G1 however does not.How can i enable bitlocker and write the key to the Active Directory for this laptop?


It looks like that setting can be found on page 20 of the manual under the Secourity -> TPM Embedded Security -> TPM State menu. Here's the link to the manual with detailed settings for the BIOS: http://h10032.www1.hp.com/ctg/Manual/c04947557

We very large office with 300 users, recently
received 20e3 Lenovo Tablet running WIN  8.1, we want to work with Bit Locker (Microsoft's encryption system) with the TPM, we have some urgent questions.

working with a TPM + Pin code, if you're wrong 33 times in the pin code of the TPM is locked and I have to do recovery with key password long, errors are cumulative, which is problematic for us , because most of the users on the ground and we can not give
them a password recovery , password recovery not transferable for users.

1. Do you know of locking the TPM 33 times, and whether it can be released or otherwise reset it without
user intervention. (Is it related to the manufacturer?)

2. The second solution came in organizing this work only in a pin code, the question is how it is secure, and where the keys are kept?
(We can not work with a USB flash disk) Thank you very much. Hezi.

I have read quite a lot about Bitlocker, but still very confusing. I would like to ask several questions for confirmation:
1) Microsoft introduced that bitlocker can protect unauthorised access to the encripted drive. Does it mean that it also can act as an anti-virus?
2) i have just turned on the bitlocker to encript my C drive and save the key file ( a text file that contains keys inside) in to my E drive (my laptop has 3 drive A C E ). But nothing different i can see after encripting it, i.e. i still can turn on the laptop and access to the C drive which i have encripted, permenently delete some file there. So it means that if unauthorised people get my laptop, they still can access to the drive and make changes in it---> i'm very confused


A:What does exactly Bitlocker do?

Hello hinhtoi, welcome to SevenForums.

BitLocker is more targeted towards portable drives such as a USB Flash Drive. To keep the files safe on it. Lets say your an executive at Microsoft and you just finished up some very important coding for a new program, and you put it on a flash drive and ended up losing the flash drive. It'd be near impossible for the person who finds it to get the files off of it. At most they could just format the flash drive but that would just wipe out everyone on it completely.
