Unable to encrypt drive using BitLocker on T440s running Windows 10

Q: Unable to encrypt drive using BitLocker on T440s running Windows 10

I am trying to encrypt my drive using BitLocker. I am saving the key to a USB drive, only encrypting used data, and using new encryption mode. I then run system check before encrypting the drive, and when I restart my computer, I get the following message: "BitLocker could not be enabled. The BitLocker encryption key cannot be obtained from the Trusted Platform Module (TPM). C: was not encrypted."I've done some troubleshooting elsewhere, but can't find any info to help me. I'm running Windows 10 Pro on a Lenovo T440s machine. My TPM is initialized, owned and running, so I'm not sure what to do there. Here are images of my TPM from Device Manager.I'm at a loss, and I definitely need to be able to encrypt my drive. Does anyone have any information? If you need more information about my system, BIOS, etc., I'll be happy to oblige. Thank you.

Preferred Solution: Unable to encrypt drive using BitLocker on T440s running Windows 10

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: Unable to encrypt drive using BitLocker on T440s running Windows 10

My guess is that you deployed Win10 in legacy mode, instead of UEFI mode. You can confirm this in msinfo32.exe, look for "BIOS Mode" in the right-hand panel. It needs to be "UEFI" if you want to use TPM 2.0.

Hi All,
I am experiencing a strange issue which I hope is something very simple. 
I have an SCCM task sequence which builds a Windows 7 x64 workgroup based laptop that is destined to be used in a KIOSK like fashion, i.e. running one app. with a specific purpose. The Task Sequence Enables, Activates and Takes Ownership of the TPM. After
that Bitlocker is enabled on Drive C: and then Drive D:. A Recovery Password, the TPM and a PIN are added as Key protectors.
The partition scheme is:

Boot partition (100MB) - standardSystem Partition (60GB)Data Partition (Rest of drive)
The issue I have is that the Enable Bitlocker (C:\) step is failing. When I check the state of the TPM, it is indeed enabled, activated and ownership has been taken. The command that is run during the failing step is "manage-bde c: -on -rp [valid password
When I run this command the error is:
"ERROR: An error occurred (code: 0x8007001f)
A device attached to the system is not functioning"
If I execute the next task sequence step ... "manage-bde d: -on -rp [valid password here]." the command runs as expected and enables Bitlocker as expected. The D:\ drive fully encrypts and after a reboot locks (also as expected given the OS dive
is not protected). It is only the OS partition that I cannot encrypt. I get the same experience after a reboot, if I use the Bitlocker Control Panel applet, even if I clear and re-initialise the TPM.

A:Bitlocker issue - Unable to encrypt the OS drive. All other drives are OK.

Hi All,
I have determined the differences in hotfixes between our previous base OS image and the current base OS image. Hotfix KB2799926 is the culprit. After removing this hotfix I can enable Bitlocker on the OS drive. If I disable bitlocker, put the hotfix back
on and reboot I get the same error as reported above. Interestingly enough KB2799926 relates to Bitlocker-to-go.
I am logging a call with premiere support and will hopefully post the results here.

Hello to everyone,

I am new here and "fresh" with BitLocker encryption. I need to encrpyt OS drive of laptop with Windows 8.1 and TPM chip. I have read few articles about encryption of OS drives with BitLocker ( with TPM / without TPM ) but never got a direct answer to my questions. So ... I want to ask:

1. Is it possible to encrypt the drive without using the TPM in case that there is TPM chip in the laptop because from what I have read BitLocker work with TPM by default but I don't want to use it. I have had already encrypt other laptops without TPM chips by setting up the group policies ( Computer Configuration \ Administrative Templates \ Windows Components \ Bit Locker Drive Encryption \ Operating System Drives and double click on Require additional authentication at startup ) and ... is it possible something like this to be made in this case ( when the laptop have TPM in it ).
What I want is the user to be asked for password on startup, recovery key to be saved to a file on external device( not to use usb flash drive as a key ) and to be possible simply to change my HDD in the future without need to manage TPM.

If this is not possible ... here is my second question:
2. Can I setup encryption with TPM like that:
- user to be asked for PASSWORD on startup
- recovery key to be saved to a file ( I don't want every time to use usb flash drive with recovery on it to unlock the drive ... what I want is just user to be asked for a password and... Read more

A:BitLocker- encrypt OS drive without TPM, if TPM is present

Good morning or afternoon Stilcho and welcome to Windows Eight Forums:
BitLocker works for me as you described without TPM enabled. I think you can even set it to 'Auto-Unlock' if you're certain your PC is not accessed by anyone else but you.
I am not well that versed when it comes to TPM/BitLocker issues but there is many helpful members here that are more than willing to help you further. Be patient and check back often.

I have Windows 10 Pro on my main laptop, but only Home on my secondary laptop. I was wondering if it's possible to encrypt the secondary laptop's boot drive. I imagine it's not possible, but I thought I'd ask anyway.

Initially I thought to take the SSD out of the secondary laptop, and place it in a SSD to USB converter. But then I was thinking that if I encrypted it that way, it'd be acting like a USB instead of an internal drive. I could be mistaken; let me know if that is indeed the way to do it.

Otherwise, let me know how impossible it is without purchasing Pro on the secondary laptop.

A:Use BitLocker to encrypt another laptop's boot drive?

Doubt that'll work, pretty sure you wouldn't be able to unlock it to boot it.

Use VeraCrypt to encrypt the drive instead, it's free: https://veracrypt.codeplex.com/

Hi There

I upgraded a HP laptop to the newest windows 10 version and as per organization requirements started bitlocker encryption on the windows drive.  While the encryption was running the user who uses the computer, for some reason had restarted
the computer while encryption was in progress.

After the restart, it showed an error 0xc0000225 "Unable to find file winload.exe" 
It was not displaying the Bitlocker unlock screen so as to unlock the drive.
I also saved the recovery key and have it printed. 
Although after booting using a win10 usb and using CMD off the bootable usb to try unlock the drive, it did not work.
I used the command  x:\>windows\system32> manage-bde -unlock e: -rp "the 48digit key" 
but it said the password wasnt able to unlock the drive. Not sure why as I have the right key. 
Also note that I used the new encryption method that works only on windows 10.

I also tried removing the harddisk and connecting it to another PC that has windows 10 version 1511 and when clicking unlock drive it says that I need a newer version of windows to unlock the drive. How can that be when I have the newest version??

The user has some important data to recover and any help is appreciated to unlock the drive
The HDD is also a samsund SSD drive

My setup: W7 Ultimate x64 on ThinkPad T510. 1HD, two partitions (C and D).

I just reinstalled my system and encrypted C; however, there is absolutely no option to encrypt D. I've tried accessing the drive from admin account and still nothing. When I open BitLocker management, it only lists partition C and not D.

Here is some additional information that might or might not matter: I tried to restore my W7 from an Acronis image and it was unsuccessful. Tried it twice and during booting POST showed two different W7s installed, which was incorrect. When I finally installed W7 from scratch, the extra W7s were still appearing before startup and I had to use EasyBCD to remove them. Now when I am trying to backup partition C, Acronis says that my System Reserved Partition (SRP) is on partition D. My hunch is that Acronis messed up my drive D when I was trying to restore my C partition. Then when I did a fresh W7 install, the SRP incorrectly ended up in D and since SRP cannot be encrypted, that means that my entire drive D can?t be encrypted either.
Can that really be the case? If so, what is the quickest solution? I am dreading about going through formatting my 750GB HD and installing W7 and encrypting it yet again. I read somewhere that you can use software like Acronis Disk Manager to move the SRP to drive C, but I am not sure how this will work because when I open the native winodws Disk Management, I don?t see SRP there. So I?m stuck and don?t want to format my HD if what I ... Read more

A:Can't Encrypt Additional Partition with BitLocker

Hello Excelsius.

Typically, Windows 7 will create a 100 MB partition on the primary disk and will not be given a letter. This may not be large enough for Acronis Image, so you might want to make it larger and give it a letter prior to setting up Acronis. The issue is the reserved partition Window’s creates is at the beginning of the primary disk.
If you don’t want to re-format and manually create the partition on your primary disk you should be able to create the system reserved partition at the end of the disk, assign it a letter, manually select it for Acronis (if you can) then remove the drive letter. You will have to make sure to mark this reserved partition as active.
Changing the active boot partition will stop windows from booting up until you reform a boot repair in windows recovery environment from the installation disk

I've used external HDDs for months now, but today when I plug any external/portable HDD/SDD in it prompts me "Before you can save files on this drive, you need to encrypt it using BitLocker"...!!!
See attached screen shot.

I can open the drive, but I cannot do a thing with it. This is causing me all kinds of grief.

I didn't even know I had BitLocker on my laptop, as it is Windows 7 Pro. I don't want it.

There is no BitLocker option when I write-click my drive. There is no BitLocker To Go installed etc...

Can someone help me to write to my drives and remove BitLocker if needed??

I have recently encrypted my system (C:\) drive, on my W7 x64 Enterprise box. This machine is not associated with a domain. I would like to encrypt my remaining local data drives, as well. Unfortunately, when I attempt to do so I receive the following error: The specified domain does not exist or could not be contacted.

I first thought it was trying to send recovery keys to a domain controller that was not there. I have tried disabling and not configuring all relevant DS recovery options found within Local Computer Policy>Admin Templates>Win Components>Bitlocker. Reversing MS's instructions on how to enable AD key recovery and following the few similar threads have not yielded worthwhile results. I have forced gpupdate and restarted after every modification, as well. None of this has resolved the error.

I would greatly appreciate any help to resolve this annoying issue.

WARNING TO ALL YOGA USERS: BE WARY WITH BITLOCKER AND YOGA! I'm working for a small client who purchased four Yoga 500-14ISK laptops and decided that due to the sensitive nature of their work, they would like to encrypt the hard drive. They come with Windows 10 Home so I upgraded one to Windows 10 Pro through the Microsoft store. I ran through the normal BitLocker encryption process accepting all the defaults which appeared to work except that on reboot it prompted for the BitLocker recovery key - which then wasn't accepted. And yes, I did record it both in Microsoft account and in SharePoint library. And yes, I was very careful typing it in. So ended up with a trashed laptop. Fortunately, I'm a cautious kind of guy and I took an image of the laptop first with Macrium Reflect so was able to restore it to pre-encryption state so nothing lost except time. I went through the process again reading the screens with a bit more care this time and same problem. Third time, I tried the BitLocker system test and that also prompted for the recovery key - not accepted again. Fourth time I tried the old encryption format and that worked flawlessly. Windows 10 v1511 (last Nov) introduced a new encryption format called XTS-AES and this doesn't work with the Yoga. Worse, if one is not careful, you'll end up with a useless encrypted laptop that there is no way to recover from except restoring an image. It's made worse by the fact that the option to do a test firs...

I am attempting to encrypt files on a Windows 7 OS using EFS.
Receiving an error that states "The File Recovery certificate being outdated or expired is the most frequent cause of this invalid recovery certificate message".

I have located this to an expired certificate under RSoP, belonging to an account called sysadmin. The problem is that this laptop was a computer that I was given when I left my previous job. I'm presuming that account belong to the tech support team. It no longer exists under user accounts.
I've logged on with the Administrator account and recreated a certificate and generated the DRA, but still receive the same error. The certificate for sysadmin under RSoP still remains.

A:Unable to encrypt files using EFS

You're up a creek without a paddle man. EFS is non-trivial and you need the original Recovery Agent to access it.

Consider this scenario:

disk is EFS
user X has a password
user X account is deleted, but the data is kept
we discover, oops, we need something
recreate user X and even reuse the same original password
The encryption key is created such that it is unique to

the HD
the partition
the user
his/her password
time of day the password is created
The ONLY choice is to have created the Recovery Agent while the account was still active.

We have mixture of Windows 7 computers with and without BitLocker enabled. We need to pus out a gpo startup script to disable startup repair on all computers (they are in one single OU).
In order for BitLocker enabled computer to stop asking for Recovery Key at each reboot, we included the two manage-bde cmds within the startup script to disable and enable bitlocker.
bcdedit / set ...
manage-bde -protectors -disable
manage-bde -protectors -enable
However, not certain what impact would bring upon the computer that without bitlocker enable when the two manage-bde cmds are run.
Does the cmds make changes to registry key / bitlocker settings when the computer actually do not have bitlocker enable.

Hello all. I'm new to this forum, but i really need help solving a problem.
I'm still a student and i received a HP Stream 7 from a costumer saying his kid apparently damaged the windows explorer (not the internet one, the one that allows to search in documents, etc). I turned it on and yeah, the thing was screwed. I tried to factory reset it trying to solve the problem, but this Bitlocker thing wants me to enter a recovery key to format it. I've searched a bit and i would need the email and pass to get the key; the parents don't remember the email or the password. I got to the BIOS and searched for more options to reset the thing, none worked, it keeps telling me that an error has ocurred (without a code or stuff like that) and doesn't do anything.

The only thing that i can access is the BIOS and the command prompt. I surfed the internet and found some commands for disabling Bitlocker, but when i enterned commands like this:

manage-bde off C:
manage-bde -protectors -disable C:

It says that the volumen is locked, and i don't know how i can't unlock it.
All i want to do is to factory reset this thing, but i don't have the recovery key needed. All i have is the recovery id
Any help is apreciated.

The only way I can connect my laptop wirelessly to the internet is to use "none" as my choice for encryption. I am using a Siemens Speedstream 6520 from Bell Canada and my laptop is a HP Pavillion with Vista as the OS. I can't figure out what is wrong and Bell Techs (so far three of them) have been unable to solve the problem. I have tried 128 bit encryption and 16 bit but unable to connect using the code. Any suggestions would be appreciated.

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.

First post, so feel free to let me know if I'm doing it wrong...

I'm trying to run sysprep with an Windows 8.1 pro image (fresh install of 8.1,
not an upgrade from 8.0) and keep running into the following error...

The log below seems to indicate that it thinks that bitlocker is enabled, which it isn't.  I guess the first question is whether or not I'm wrong in my interpretation, and the second is has anyone seen anything like this?
Much Thanks -

A:Sysprep Failure Unable to Validate Windows Installation (Bitlocker)

I solved this same issue by turning BitLocker on and then back off again.  Once off, you need to wait for drive to finish decrypting.  Once finished, sysprep worked for me.Tim

SOLUTION FOUND: You have to delete the 100MB Partition and it will work perfectly. Link on how to do this: System Reserved Partition - Delete

edit: Summary of problem-- I get stuck on the part where TC asks you to restart in order to test the bootloader (the "pretest"). My computer restarts, bootloader comes up, I put my password in and it doesn't move past "Booting..."

Hi. My laptop originally came with Win8 UEFI on it. I hated it. So I wiped the whole thing and installed Win7 from "scratch". Changed my "BIOS" to Legacy and disabled Secure Boot.

Here is my problem: I'm trying to encrypt my whole system using Truecrypt. In theory it should work, because my disk is MBR: http://i.imgur.com/j4r4BRm.png (I also checked via cmd.exe if my disk was MBR, and it was)

Picture of my dxdiag: http://i.imgur.com/5H2VOEc.png

However, TC gets stuck at "Booting..." and I have to unplug & remove the battery in order to boot the laptop. Whenever I boot it back up, TC tells me that the test failed. I don't understand what the problem is. I know I'm stuck in a pretty unique situation but yea...

What can I do in order to fix this and get TrueCrypt working on my laptop?

A:Unique situation: Win7 MBR unable to encrypt using TrueCrypt

Bizarre indeed. The only thing I can recommend is to try and encrypt only the Windows 7 system partition and not the 100MB System Reserved partition.

Hi all,
Thanks in advanced for your advises :D!
The situation is as follow:
- Our AD server is 2012 R2 v. 6.3 Build 9600.
- Users below are using Windows 7 Professional and joined domain.
- I created new certificate in Public Key Policy/ Encrypting File System as Administrator and push down to the domain group
- We started doing encryption EFS for our users...most are ok, except one PC A.
- User A who is using PC A we cant encrypt his files. Pop up is 'The Parameter is Incorrect' when doing EFS encryption.
- if User B log in to PC A, his files on PC A can be encrypted. If user A log in to user B PC, his file can be encrypted as well.

- So seems like issue is only at PC A and only with user A
so my 1st Question: Why is this happening and how to prevent this? (possibility is user profile corrupted but why and where it's corrupted?


- I decided to copy all User A files (including Outlook pst), delete his profile and recreated new profile with same name
- Copy all his file over, set up outlook with old pst file again. And start doing encryption include outlook files.

- Encryption went smoothly.
- Next day (or may be when user restart etc..) when open, Outlook prompt Access denied for his pst file.
- All other files that was encrypted together with pst files (doc, xls etc.) are able to open and use normally
- At the same time, one more user reported having this Outlook access denied... Read more

I used to use TrueCrypt for this purpose. It would encrypt an entire drive easily, all partitions. One had to enter a password or the system would not boot.

I have a tablet with a 2TB SSD divided into five partitions, one WinRE, one 260-meg empty, and three others that are C, D, and E. I tried TrueCrypt and it returned the following error:

"Your system drive has a GUID partition table (GPT), Currently, only drives with MBR pasrtition table are supported"

I tried BitLocker but I see no way to encrypt the entire disk.

I tried DiskCryptor and same problem.

I want this system locked down, or at least C, D, and E, in the event it is lost or stolen as there is sensitive information on it and I don't want to have to unlock each partition separately.

Truecrypt works so well for this purpose but, alas, this is not an MBR drive. Truecrypt would present a password screen prior to starting the Windows boot process and I would like to have that kind of function again.

Can GUID be converted to MBR safely?

As a rule, I don't run NTFS on any of my systems and I advise against it in most situations. The reason is that I consider the additional stability and security that NTFS offers to be outweighed by the disadvantage of making it impossible, if not near impossible, to clean adware/spyware/viruses from an infected machine. But now I am presented with a new dilemma:

I have a laptop that I am using more as time progresses. It has a lot of information stored on it about my clients' user names, passwords, e-mail configurations, product keys (which they do lose, occasionally). Losing the laptop to a thief and the potential that the thief would discover the valuable and sensitive information stored on it . . . Well, I think you get the idea.

I am thinking of converting the laptop to NTFS and encrypting the many folders that contain sensitive information, thus protecting my clients from any potential damage due to loss of the laptop.

Here's the proposed scenario and conditions:
The laptop's hard disk is converted to NTFS.
Folders containing sensitive information are encrypted.
The OS on the laptop crashes and is unrecoverable.
I am forced to trash the existing OS and set up Windows 2000 or XP fresh and clean and start over again.
What must I do now to prepare for this day so that after the OS is loaded again, I can access those encrypted folders?

A:To encrypt (folders) or not to encrypt--that is my question.
