Bitlocker unable to unlock drive using Windows 10

Q: Bitlocker unable to unlock drive using Windows 10

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

Thanks

Hey All,

Recently my company provided me with a Windows 10 SOE image as part of a UAT. The image includes Symantec Endpoint Encryption which utilizes Bitlocker for encryption.

I went through all of the motions with the C:\ drive to be encrypted and even printed the recovery key. Well, at some point I plugged in a few My Passport USB drives and they became locked by Bitlocker To Go. Everytime I try to unlock or click on these drives it asks for the 48-bit key which I don't have because I never was prompted to encrypt/lock these drives.





IT says that there are no keys stored on the servers for these USB drives and suggested that this would be a "local" encryption. However, they also stated that they wouldn't be encrypted unless I was prompted about it. So, there's this mystery about how these USB drives came to be locked.
I've been doing some research and the closest I've come is getting some output about the protectors:

I recently connected an iscsi drive to my asus tablet. I was not aware that bit locker was on. when I disconnected the drive I could not access it on my other pc. I reconnected it to the asus tablet and went to the system screen and turned off bitlocker. I got the screen saying that it was decrypting the drives and I thought all was fine. when all was done I rebooted the tablet and checked the drive. it only decrypted the system drive and tells me the iscsi drive is locked and wants a key. the system never told me it was locking it in the first place and never prompted me to create a key file.

Hey, I'm trying to configure my secondary internal HDD to lock with bitlocker, since acronis won't back it up well with truecrypt, but I still want to encrypt my OS drive with truecrypt since I don't have a TPM, and have to use a USB key to unlock it at startup, which I think is a vulnerability since anyone can just grab my USB and plop it into the computer. Is there any way I can bypass this restriction, or even better, have BitLocker require a startup PIN without having a TPM?

Hi,

I have 2 drives on my PC. One SSD where Windows 8.1 is installed and a secondary HDD for movies and stuff.
The SSD is Microsoft edrive compliant so I just enabled BitLocker encryption and set a password, i.e. Pass1.

Later I also encrypted the secondary HDD and DID NOT save the recovery keys when doing that. I clicked smth like Automatically unlock or smth when doing that as the secondary drive was always available when logging in to Windows later. No need to enter a separate password.

Now, I formatted the primary SSD and re installed Windows 8.1 but now I don't have the recovery key for the secondary drive. Is all the data lost or I can somehow use the password to unlock it?

Thank You

Folks,

Many hours of googling have not yet yielded a solution...

I have a .bat file that requests input of the PIN to unlock a bitlocker encrypted partition.
I would like to run this before windows LOGON (ask for password during boot).
This is because I placed several of the user directories (desktop etc) onto that partition.
If I do not unlock the drive before login, desktop does not load, and other startup programs (e.g., dropbox, skydrive) cannot access their folders and fail.

I have tried scheduling a task at start up, without success.
The bat file needs to be run as administrator - but even when I indicate "run with highest privilege" it won't run properly.

I have basic knowledge or task scheduler, cmd line, and registry editing (BASIC knowledge...).
So any help you can provide (with details) would be much appreciated!

Hi,

I have a Microsoft Surface Pro 2 and I am running Windows 8.1 Pro Update 1.

I have been unsuccessful at building a WinPE image that provides BitLocker support. I searched around the internet and found many posts. Eventually, I ended up trying to build it with the various added packages I discovered in the various posts. However, in the end, none worked and this is the message I am getting after booting into my WinPE environment:

manage-bde.exe - Application Error

The instruction at 0xa20afa3b referenced memory at 0x0000013d.
The memory could not be read.

Click on OK to terminate the program

Here are the commands I eventually ended up using to build my WinPE image:

A:How to enable BitLocker support (unlock drive) in WinPE 5?

I resolved the issue, but here's how I got to it:

1) I even tried using the 8.0 ADK, but I still got the same error.

2) At one point during my troubleshooting, I stopped just prior to performing the Commit to create the WinPE image. Then I navigated to the <mount directory>\Windows\System32 and ran manage-bde.exe. The result: A Windows error (something to the effect that the program crashed/stopped working).

3) I tried running Notepad.exe and it worked fine.

4) I compared the manage-bde.exe from my mount directory to the one in C:\Windows\System32 using the comp utility and they were identical.

5) I have always been able to run C:\Windows\System32\manage-bde.exe. So I created a "temp" subdirectory in my mount directory and copied C:\Windows\System32\manage-bde.exe. When I tried to run it, I got that error (program crashed/stopped working).

6) Running it from the C:\Windows\System32 directory, however, worked without any issue. This led me to conclude that it required some dependent files in C:\Windows\System32.

7) After a bit more troubleshooting, I discovered that in order for it to run, it needed something in directory C:\Windows\System32\en-US\. I copied that folder I into my "temp" folder on my mount directory and then manage-bde.exe was able to run without any issues.

8) Final solution was to create a subdirectory called "BitLocker" in <mount directory>\Windows\System32, then copy C:\Windows\System32\manage-bde.exe... Read more

Hey
My company is updating our windows, servers, desktops nearly every thing. we were asked to back up all our data on external drives, but we were forced to encrypt the drives with Bit locker, after the immigration to the new hardware and windows 10, I opened
my external HDD and USB Drive using the passwords I set earlier, and as I don't need the drives to be encrypted anymore, I right clicked the drives then choose "Remove password" which I thought it will decrypt the drives and no passwords will be
required anymore. I was surprised to find that my drives are still encrypted, and all what happened is that the password unlock option for my Bit locker encrypted drives was removed. it now only displays to option to unlock (another USB drive or recovery key)
and I don't have both. all what i have is the passwords that I set to the drivers, but the unlock with password option vanished.
can i return that option back so i can unlock both my drives using password? can you please advice?

Team - Trouble here!! Have ~730 GB of data on my 1TB iOmega HDD. Turned on BitLocker on my Windows 7
system, set password, created and saved recovery key file, and i saw it started encrypting (very slowly, which i think is normal). Left it there for hours and when i came back I saw it is asking me for my password for my unlocking... which i entered and it
just wont open. Goes "NOT RESPONDING". I did not lose power during the initial encryption and neither did i pull out the HDD (to my knowledge) even though I read in the MS content that encryption should resume the next time a drive is plugged in,
it it got interrupted the first time or whatsoever.

However, started my research and was shocked to find several people have had similar problems. Also references that data must be backed up before encrypting (may
be common sense). Well, i have not done that, did not know that a simple of act of encrypting could be such a crime, especially when you are encrypting what you have just taken a backup off - before proceeding towards a formatting of my laptop.


Tried the manage-bde commands and the results are in a pic that i cannot attach. Interestingly, i find that the "manage-bde -status" command shows "conversion status" and "percentage of encryption" as unknown. Is this normal? I

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.  

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.

I was running Windows 10 and there was some sort of error that forced my computer to shut down and restart. When it did, bitlocker was asking for a recovery key. I used the recovery key that is listed on my Microsoft account (I made sure that the key ID
matched the one displayed on the computer) but it said that the key was wrong. 
After attempting this a few times, I gave up and hit "skip this drive." Since then, that drive is completely locked.
Since my computer has two operating systems, the second being an old Vista install, the Vista started up. I used the command prompt (in Administrator mode) and ran the manage-bde -status command. 
the output was as follows

I tried to unlock using manage-bde -unlock g: -recoverypassword.
Nothing is working. I never lost my unlock password and I've tried using that too but it didn't work.

A:Help me plz..... unlock bitlocker

From a Microsoft article about BitLocker:






Quote:
When a local administrator initializes BitLocker, the administrator should also create a recovery password or a recovery key. Without a recovery key or recovery password, all data on the encrypted drive may be inaccessible and unrecoverable if there is a problem with the BitLocker-protected drive.


Source: BitLocker Drive Encryption Overview

But I also found another Microsoft article that may permit using a Data Recovery Agent.

Scenario 14: Using a Data Recovery Agent to Recover BitLocker-Protected Drives (Windows 7)

The problem is, drive encryption is supposed to be secure. It's supposed to make it difficult, if not impossible, to recover data. Otherwise, what's the point in using encryption if everybody can just hack their way in.

Put an appropriate key and nothing happened afterwards, everything is hang up and only possible to switch off with power button
2) start from CD/DVD drive chose unlock drive via cmd put command manage-bde -unlock C: -RecoveryKey ... and left laptop for 1-2 hours but I didn't got any resultant message that drive is unlocked.

However, with it being a tablet and conscious of its portable nature, I wanted to encrypt the MicroSD card using BitLocker (the C: drive is encrypted on the tablet by default) - but this edition of Windows 8.1 won't let me encrypt the SD card.

So I put the SD card into my Windows 10 Pro machine, and it allowed me to encrypt it and I have the key (written down as well as stored in my Microsoft account) - it took a long time to encrypt. When I plug the SD card back into my tablet, it prompts me to enter the password I set when encrypting the SD card on the Windows 10 Pro machine. But it isn't recognised. I've also tried the 48-digit recovery key, but this does not work either - it just reads "The password entered is incorrect" - I can assure that it is correct! If I plug it into my Windows 10 machine, it again asks for the password - which it accepts!

Is there anything I can do to get the BitLocker encrypted card to be unlocked on my Windows 8.1 tablet??

If not, is there any way to get Windows 8.1 standard to allow me to encrypt the MicroSD card volume?

Thank you for any feedback and help

Hi ,
The Bitlocker autounlock for an External drive on my PC got disabled and it asks for Recovery key after i ran a PC Cleanup. It is not able to recognize my PC anymore. The worst part is i am not able to locate my Recovery Key.
I can try to recover files deleted by the cleanup tool but i am not sure which particular file stores the key information to help Bitlocker recognize my PC.
Please let me know if there is any other way i can unlock my Drive.
Thanks

I'm not even sure how to title this.

I just did a fresh install of Window 10. I do not have a TPM so I setup Require additional authentication at startup. I set up my C: drive with my bitlocker password and rebooted.

When it comes to entering my bitlocker password, I get many characters per keystroke. Mostly on the capital and special characters. I've switched keyboards, tried different USB ports, etc.

If I go into my BIOS setting, everything works. Once I get my drive unlocked, everything works fine. The multiple characters only happen when I am unlocking drive during booting.

My motherboard is a Gigabyte GA-Z77X-UD5H (rev. 1.1) and my keyboard is a Logitech K520. I did not have this problem with Windows 8.1, or Windows 7.

How do I fix this?

TIA

-JJ

A:HOW TO UNLOCK A DRIVE PROTECTED BY BITLOCKER WITHOUT ITS PASSWORD AND RECOVERY KEY ?(I LOST MY PASSWORD AND RECOVERY KEY)

Hi  ashish,
The drive must be unlocked by the recovery password or recovery key. But you lost it and haven?t print the recovery information or save it anywhere. No any other method to help you.
I am sorry for that. I suggest you consult professional data recovery company.
Best regards,

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
here]"
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.
Cheers,

I enabled BitLocker and I noticed that the option to save the recovery key to a USB Flash Drive is not there. Instead, there is an option to Save to a File and did let me save it onto a USB stick without issues.

However, in case I get locked out, will BitLocker prompt me to Insert Storage Media like from the image taken from a Windows 7 machine or will I need to go to another PC with my USB stick and write it down manually? And I don't even have a printer to print the key. And I don't want to use a MS account either.

Has this option been taken away from Windows 10?

Please Note: I am indeed running with a TPM.

Win8.1 Pro x64

Been having a weird problem lately. Whenever I unlock a BitLocker volume (I have two of them), I can't access it. The system doesn't even provide a drive letter. If I try accessing the drive letter in Directory Opus (where the drive letters are always shown, whether the volumes are unlocked or not), I get an error saying the drive does not exist.

But if I lock and immediately unlock the volume a second time, all is well.

I don't understand this at all. Anyone?

A:Have to unlock BitLocker volumes twice to gain access

No one? This has to be one of the stupidest, strangest problems I've ever encountered--and I've been using Windows for ages.

I changed the password on both BitLocker volumes, but it didn't make a difference to this issue.

I have 2 storage hdd encrypted w/ bitlocker, in addition to the encrypted OS volume C:.

I activated auto unlock expecting the storage volumes to automatically unlock with the unlocking of C: (I enter the psw during boot since I don't have TPM). However they stay locked until I open them and manually enter their psw.

Looked everywhere on the internet for solutions but the problem is still here, so I'm posting asking for help.

Things to know:
- storage volumes are seen as removable, instead of fixed (I guess because ahci is set, so should be normal)
- the two storage volumes have been encrypted before encrypting C:, and have different psw from C: (shouldn't matter either, but you never know)
