BIOS flash error, BITLOCKER on? No bitlocker installed, Win 7 Pro

Q: BIOS flash error, BITLOCKER on? No bitlocker installed, Win 7 Pro

I tried using HP BIOS Flashing utility on my HP Z400 Workstation, and it says it can't continue because I have Bitlocker enabled, but I don't have bitlocker on Win 7 Professional 32bit. I don't see it on the control panel or in context menus. I do see it set to manual in "Services" but the service in not running. Is there a way to find drives Bitlocked or are my drives being treated as bitlocked because of my antivirus program AVG?

Preferred Solution: BIOS flash error, BITLOCKER on? No bitlocker installed, Win 7 Pro

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: BIOS flash error, BITLOCKER on? No bitlocker installed, Win 7 Pro

In the services window is there and option to disable or turn off...there should be. Just change the startup type from manual to disable and reboot. Then try your BIOS update.

Hi , 
I locked my external hard disk (Seagate- 1 TB) on Windows 7 laptop . The encryption was successful but when I later tried unlocking it, Its giving an error. Error
says "bitlocker drive encryption failed to recover from an abruptly terminated conversion". Please note that the Password and Recovery Key are correct and I have tried unlocking it
several times but no success.
Upon searching on internet, I came across the below thread which I yet need to try. Pray that it gets unlocked as I have got very important data locked up and the drive
volume is also 80-90% filled. 
Please help me out experts to get my data back.<o:p></o:p>

In our organization we have a policy to require Bitlocker flash drive encryption. This is set via Group Policy. I am having an issue on some computers where when they select to encrypt their flash drive for the first time, they get the following error message:
BitLocker Encryption cannot be applied to this drive because of conflicting Group Policy settings.
When write access to drives not protected by BitLocker is denied, the use of a USB startup key cannot be required. Please
have your system administrator resolve these policy conflicts before attempting to enable BitLocker.

Comparing to my laptop which is working, here is what I've gathered:

Same OU/Group PoliciesNo group membershipsSame TPM settings in BIOS and TPM Management ConsoleTried multiple flash drivesDoesn't matter who is logged in. Local admin, Domain Admin, or the user of the machine.
We do not require a USB startup key (obviously) and the policy is set to store the recovery passwords and key packages in AD DS. Another thing is the workstation HD is encrypted and the recovery key is in AD, so that tells me at least at one point it had
a healthy relationship with the DCs.
I am convinced it is not an issue with the policy, as there are currently only 2 users complaining of this issue out of 450. Where do I go on the workstation side of things to see what is happening? For your peace of mind, I have isolated the workstation
in it's own OU with only one policy applied. Here is what the policy ... Read more

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.

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

 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

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.

Hello and good afternoon, I have a issue where a manager started the Bitlocker process on the SD card in his Surface Pro 3

with Windows 8.1. The Bitlocker attempt failed at 3.4% completed but the SD card ended up being Bitlocked without providing the Bitlocker Recovery Key (I've never seen this happen before). He doesn't know the password for the SD card and of course
I've been tasked to somehow release the encryption so that he can get the required information off of the SD card. 

Is there anything that can be done to release the encryption on the SD card or has the SD card been made non-accessible moving forward?

I turned on Bitlocker on three new Windows 8.1 laptops and saved the 48-digit recovery keys and associated identifiers, but I forgot to indicate which laptops they are associated with. Is there any way to find the identifiers/recovery keys on my laptops so I can document this? Or do I have to decrypt the laptop drives, turn off Bitlocker, and start all over again to generate new identifiers/recovery keys? My only options under Manage Bitlocker are Suspend protection, Back up your recovery key, and Turn off BitLocker.

Hello Edwin, and welcome to Eight Forums.

No worries. If you should ever need to unlock to drive, it'll provide you with a recovery key ID number that you can use to ID which recovery key to use. The tutorial below can give you more details about this to help get an idea if ever needed.

Initially I found that BitLocker on the Go supported removable media like flash drives and external drives. Why isn't a CD/DVD supported since it is considered removable media? Will this support be available in future releases?

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.

My wife want her laptop locked down with bitlocker and a usb flash stick(laptop does not support TPM) Never used bitlocker before and i don't want to brick the system and have to reinstall.

She has one physical drive split into 2 partitions, my question is can i bitlock both drives and use the same(one) flash drive as the keyholder to unlock the windows drive as well as the second partition(she does not want to have to input a password{lazy}?

Have looked but can't seem to find the answer, I know i can store the recovery key on the same stick, but since i dont know how the actual unlock key is written to the usb stick I don't want to encrypt the win drive with a key and then have that overwritten with the key for the second partition.

A:Bitlocker with a usb flash drive??

Hello Ba5ik,

Yes, you can save both recovery keys onto the same USB flash drive without any issue. Just keep a backup of both of them in separate folders on the USB flash drive as well to be safe.

For Windows 7 partition:
BitLocker Drive Encryption - Windows 7 Drive - Turn On or Off with no TPM

For other nonsystem partition:
BitLocker Drive Encryption - Internal Data Hard Drives - Turn On or Off

I followed the step by step guide on what Brink wrote up below.
BitLocker - Turn On or Off for Operating System Drive in Windows 10[1]=Security System Tools

However, when turning ON BitLocker to encrypt the OS drive only, and ask me to where to save the recovery key, I get only the Save to File and not the Save to USB Flash. Has MS taken out the Save to USB selection since WIn 10 version 1511?

I followed all the steps and left BitLocker to its default setting (except for encryption method).

I was able to save the recovery key to a file which was my USB flash drive.

A:BitLocker Save to USB Flash missing?

No, Bitlocker works fine on 1511 and whether you save your key to USB, use a password or whatever is defined in group policy.

Please let us know what gpedit.msc settings you have made. The various settings are described in the tutorial.

The help page for BitLocker mentions

"A removable USB memory device, such as a USB flash drive. If your computer doesn?t have TPM version 1.2 or higher, BitLocker will store its key on the flash drive. This option is only available if your system administrator has set up your network to allow the use of a startup key instead of the TPM."

SOLVED - see last post.

My query is regarding a brand new i7 sixth generation computer with Windows 10 Professional, including all the Windows upgrades, and a new Samsung SSD hard-drive.

The reason I bought Windows 10 Professional was for the full hard-drive encryption provided by Bitlocker in case my computer gets lost or stolen, as has happened to me previously. However, I have an ongoing problem with it and can't find a solution anywhere. I have tried to telephone Microsoft's telephone support several times but it has been beyond a joke with their outsource staff in far-flung countries with poor English claiming Windows 10 Professional does not have the option of Bitlocker or any form of encryption to all kinds of other absurdities.

Whenever I start my computer it does not ask me to enter a Bitlocker username or password (I am asked for the Windows password, but, as everyone knows, those are not totally secure and do no protect hard-drive data access). Also, in the Bitlocker section in Control Panel, I am not giving the option to edit a Bitlocker password, even though that option exists in all the other screenshots I have seen on the web.

How can I set my computer up to present me with a Bitlocker password on boot-up?

My system does say my hard-drive is encrypted, but how can I certain of that if there is not even password protection?

Here is what I see in my Windows Control Panel > Bitlocker section:

I note the warning message about rights being restricted t... Read more

A:Installed Bitlocker does not ask for password on computer start-up!

You can't change the bitlocker key and it would be impractical to enter it (it is 8 blocks of 6 numbers). This is the number you have to enter to unlock your drive to access it if it isn't unlocked by normal methods. This would prevent someone taking your disk out and being able to read it which can be done very easily if you don't have bitlocker enabled (which you do).

Your recovery key is on the USB you saved it to when you enabled bitlocker (if you saved it to USB) or here RecoveryKey if you saved it to your OneDrive.

What you can do is chose if what is required to unlock your drive when you boot (whether you need a pin, password, usb key). This is changed under gpedit.msc

There is a tutorial here somewhere - I'll see if I can find it. In the meantime what model of computer do you have exactly? Does it have a TPM (Trusted Platform Model) chip?

EDIT: Here is a windows 8 tutorial BitLocker - Turn On or Off for OS Drive in Windows 8

It is much the same except Windows 10 (version 1511 and later) allow stronger XTS-AES encryption - again set in gpedit.msc under Computer Configuration > Admisistrative Templates > Windows Componenets > Bitlocker Drive Encryption > Choose drive encryption method and cipher strength (Windows 10 [Version 1511] and later)

The separate bitlocker password is for non OS drives - see here BitLocker - Turn On for Fixed Data Drives in Windows 8 or BitLocker - Turn On for Removable Data Drives in Windows 8

Hi All,

I have been looking on the internet but can't find anything useful.

I protected data on my USB flash drive using Bitlocker in Windows. But of course I can't access it inside Apple OS X operating system. Yes I have a Windows VM running inside my MacBook and can access bitlocked flash drive this way, but this requires booting
up Window VM and becomes frustrating most of the time.

Does anyone know any possible way to access bitlocked flash drive directly inside OS X?
If the answer is "No", then my request to Microsoft is to please make a Bitlocker Reader/Access tool for Mac OS X and make everyone's life easy. This will definitely increase number of Bitlocker users; a win-win situation!

I have a Precision Mobile Workstation 7510 running WIndows 10 with two drives. I have Bitlocker enabled on both drives.
Dell Command Update recently notified me of a BIOS update but warned me that I must suspend BitLocker protection to perform the update.
I suspended BitLocker on the OS drive, but it appears that Windows 10 does not allow me to suspend BitLocker on the second drive. My only option to turn BitLocker off on the secondary drive is to do a full volume decryption, which takes hours (it's a 2GB drive).
Turning BitLocker off on the OS drive does not seem to convince Dell Command Update that things are ready for the update. I suspect that it is the fact BitLocker is still enabled on the secondary drive that is causing Dell Command Update to balk.
So, questions:
1) Am I deducing the problem correctly? Is it the fact that the secondary drive has BitLocker still enabled that is stopping Dell Command Update from updating?
2) Is there any way to convince Dell Command Update to proceed with the update?
3) If I manually install the update (bypassing Dell Command Update) without completely disabling BitLocker on the secondary drive, will there be any adverse effects (such as being unable to access data on my secondary drive)?

I have a Dell XPS 15 9550, and after a recent BIOS upgrade, it seems to have lost the PIN, and is asking me to enter a BitLocker recovery key, which so far at least, I've been unable to find.  So does anyone know how to:

Reenter the PIN so that the system boots normally (TPM/UEFI/etc.)?
If that is not possible, re-install Windows 10?

The system was upgraded right after purchase from Windows 10 Home to Pro, otherwise is pretty stock.  
When I go through the various recovery options to Troubleshoot:

Reset this PC:  It asks again for the recovery key (which I do not have)
Advanced > System Restore:  Same (recovery key which I do not have)

I realize that the without the Bitlocker recovery key, that the data may be all lost, but what I would like to do is get the system running again, at least to the point I can re-install Windows.  I have the PIN of course, but cannot seem to get to the point where the system prompts for it, it is stuck on the Bitlocker key, which I cannot find.

Confirm that the boot changes to this system are authorized.
If the changes to the boot system are trusted, then disable and re-enable

Otherwise, restore the system boot information.

I had a lot of issues with the screen blinking/flickering on/off when removing the laptop from the WD-15 dock and read that the new BIOS upgrade would fix this issue so I went ahead and upgraded the BIOS.
I installed "DellDockingStationFwUp_1.0.0.8_20161220_WD15.exe" and "XPS_9550_1.2.21.exe".
I added Bitlocker protection the first thing I did when I got the laptop about a year ago and it has been working fine.
After this upgrade (with or without) the dock attached I get the Bitlocker code prompt at every start of the laptop.
I can't seem to roll back the FW upgrades as the installer tells me I have a newer version installed...

A:Windows 10 Bitlocker code required every time after BIOS upgrade on XPS 15 9560

After searching and checking I found that I no longer have any compatible TPM according to Windows.
(Win 10 Enterprise 64bit Build 14393)
Looking in the BIOS there is no setting for TPM anymore so then I found a way to rollback BIOS FW.
It was by shutting down, unplug the power plug and then keep CTRL+ESC pressed while plugging in the power plug. That brings up a prompt where I could do a rollback and after that tehre still is no TPM in BIOS. I run the same again but this time I chose to reset the BIOS settings, still no TPM!
I still have to give the Bitlocker key at every startup and to top it off the laptop no longer goes to sleep when the lid is closed, it shuts down even though the settings is to "sleep".
This of course means that every time I carry it around I have to add the Bitlocker key when picking it up.
Our corporate network requires Bitlocker so I can't use the laptop without bitlocker in the domain.
Any suggestions?

That BIOS sadly does not work ...? Why?

Bitlocker encrypted my whole drive.
it starts correctly and displays the keyboard.
GPO: Keyboard Slates (or something like that) is activated.
BUT: Touchscreen does not work. That means.. i can see the keyboard but it does not work.
thats why i wanted to update my bios but it says it is not working on my computer... well thats frustrating...
why offer the bios update when it does not work at all... or is it some sort of windows 7 only? cant imagine that tbh.

i guess the only problem is the bios but i could be wrong (z20t-b works on same settings for example)

Failed to run the action: Enable BitLocker. The BIOS did not correctly communicate with the Trusted Platform Module (TPM). Contact the computer manufacturer for BIOS upgrade instructions. (Error: 80310002; Source: Windows)
Can someone please confirm issue with this latest BIOS and will need Dell to re-evaluate.

A:Dell Latitude E7270/E7470 System BIOS 1.15.4, Bitlocker fails

So far, I have seen two threads (Latitude E7470 & Latitude 5280) who went to the latest BIOS and now TPM is not available. Attempting to downgrade a BIOS is always risky as it could "brick" the motherboard CMOS if it fails. Makes sense that the image failed because the image was made when TPM was enabled. For now, all we can do on the Forum is gather the system models, BIOS number, and usernames and track it.

I've experienced quite the snag with Bit Locker.

In an attempt to encrypt my 2TB (1.81 TB) HDD my computer decided to crash 43% into the encryption. Leaving the drive inaccessible, and completely useless.

After some searching on Google I found out about the repair-bde line in command prompt. Following I attempted a repair.

repair-bde E: J: -rp (RECOVERY KEY)

Mind you this is after I went out and purchased a second 1.81 TB hard drive so I could successfully repair.

Following that command I get the error:

LOG ERROR: 0x000003c
Need atleast 1907727 MB of free space for repair.

ERROR: Not enough free space on output volume to preform repair.
Apparently my 1.81 TB hard drive isn't big enough to repair my broken 1.81TB hard drive, that was only 40% full...

Is there any work around, or any other way that I may be able to recover the data from this drive? This was my main drive for pretty much EVERYTHING. Music, Movies, Pictures, etc.

It is essential I recover the data on this drive.

Any suggestions?

I am trying to enable BitLocker on a Windows 7 machine but when I go to save the startup key on my USB drive, I get the following Error:  The startup key could not be created.  Try again or restart the BitLocker Wizard.  I am sure it is
something within windows (policy or registry).  I opened up the policy editor but nothing jumps out.  I have looked in the bitlocker portion and the removable media portion.  This is in a virtual machine and works on other systems.  This
is a stand alone locked down system. I can write to the usb drive and it shows up as a removable drive in the BitLocker Wizard.

Dear All,

We are facing an issue with bitlocker on Windows 8 machines since its not encrypting Hard disks through GPO. we are getting the below error on the log files

failed to initiate drive encryption with the following exit code: 80070057

We are using the same GPO for windows 7 machines and its working completely fine and also Bitlcoker_to_go is working fine with both OS's.

Friends, is there anything specific in GPO to check for bitlocker encryption in windows 8?
