Windows 7 Bitlocker Error "bitlocker drive encryption failed to recover from an abruptly terminated conversion"

Q: Windows 7 Bitlocker Error "bitlocker drive encryption failed to recover from an abruptly terminated conversion"

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>

At first, I don't need to recover my data, I just want my drive back to re-use it.

How can a format my USB drive including all boot sectors which sees to be locked/write-protected by bitlocker?

My problem starts with encrypting my drive by activating bitlocker. At 30% of encryption the process halts without reason. Now, I'm unable to access my drive or resume the process.

I tried...

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

I'm running Win 10 Pro version 1607 (OS Build 14393.321), and I have a weird problem with my 298 GB WD in 2.5? SATA enclosure external hard drive. I have used it several times in the past to backup Windows 7 & 10, but now I can use it to backup Win 7 only not Win 10! I believe this problem may have started after I performed a quick format on it using a Win 10 machine, and also ran CHKDSK /R in order to mark the bad sectors.
Now when I use it to backup my Win 10 machine, backup fails with error 0x8031004A: "BitLocker Drive Encryption cannot be used because critical BitLocker system files are missing or corrupted. Use Windows Startup Repair to restore these files to your computer." Also if I click on manage space it gives an error ?The backup location is not connected? even though it is connected and accessible (even shown in the backup page itself)!

Hello @Destro78 Welcome to the HP Support forum. Thank you for posting. BitLocker keys (for personal devices) are stored inside or in many case they are back-up to Microsoft cloud with your Microsoft account. Since this is a tablet, I suspect that I suspect your recovery key is available in Microsoft's OneDrive spaceHere are instructions how you can recover the key as well as how to get back to business.>> http://windowsitpro.com/microsoft-surface/locating-your-microsoft-surface-bitlocker-recovery-key>> http://www.eightforums.com/tutorials/21433-bitlocker-recovery-unlock-drive-windows-8-a.html  >> http://go.microsoft.com/fwlink/?LinkId=237614https://onedrive.live.com/recoverykey Login to the MS account there and check.Use the key to login to your PC.Eventually, if you prefer you can disable BitLocker and turn off device encryption, or save/print the key offlinePlease, note that it is very important for security reasons that you keep the encryption key (Bitlocker key) in a secure place so that only you know it.  More info - re.

I've got 2x1TB partition using raid 0 on C: drive which I recently shrunk a little to make a 10GB partition to put "secure" items into. When I try to enable bitlocker encryption on the partition, it gets part of the way through and then my computer dies horribly. It's not a BSOD, the screen is black and windows tells me it can't find its loader.

I reboot a few times and everything is back to normal. Delete the partition, re-create it, format it and try again, same thing.

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.

We are getting the above error randomly on some of the laptops we have deployed. The error comes right after you boot or when the windows 7 is left running. There are no special software running. The error in details is below.
"The boot configuration Data (BCD) settings for the following boot application have changed since Bitlocker was enabled
boot appplication: \windows\system32\winload.exe
change settings: 0x26000090
You must supply a bitlocker recovery key to start this system.
Confirm that the changes to the BCD settings are trusted.

If the changes are trusted then suspend and resume bitlocker. This will reset bitlocker to use the new BCD settings.
Otherwise restore the original BCD settings"
Can anyone please explain on how to correct this error. As before this is happening on few of the machines and we are seeing more as we go. Any tips would be nice...Thanks

It will not damage the HDD just make sure you save the "Key" in a save place not on the computer (A hard copy on paper and a digital copy on a thumb drive two backups of the key is best) also the Windows OS partition or HDD can not be encrypted using Bitlocker.

I have been having some issues when trying to turn Bitlocker on in C:

I have followed the instructions as per this forum to enable a Startup key in gpedit.msc as I dont have TPM which worked.

After following the instructions, Windows Bitlocker asked me to insert a USB to save the startup key to. This appeared to save and then moved onto the next step where I took down the recovery key etc... and finally restarted to make sure my system was compatible before encryption started.

Upon restart, Windows said that it couldnt find a key on the USB drive. After further investigation I found that windows did not save the key to the USB after all even checked as a hidden file. It will save the text file (recovery key) to usb but not the bek file for the startup key.

I have tried this several times but each time it wont save although the system dosent say there has been a problem and moves on to the next stage.

The USB is a 2gb cruzer with the smart drive software removed and re-formatted to NTFS. I have also tried this on other USB drives with no luck and the USB drives work as Iam able to write other things to it?

Any help would be greatly appriciated as I have searched this forum and MS forums with no luck.

I ran the manage-bde -status command of my encrypted OS Volume Drive and it shows 100% encrypted.
Does this mean that BitLocker encrypted the ENTIRE drive?

During the BitLocker setup, I did select to Encrypt the Entire Drive instead of the Used Space option.
I just want to double check if my entire OS drive is encrypted or not.
I assume that when it shows Percentage Encrypted as 100% then I guess it did encrypt the entire drive.

Now what if I had chosen to encrypt the Used Space only, then would it still show as 100% encrypted ?
Or am I wrong?

Hey guys I have a desktop That has Windows 7 Ultimate edition installed. My parents are having start up issues with the OS. When the OS starts up, Bitlocker Drive encryption Recovery comes up with and option to unlock 2 Drives which is a separate hard drive. it comes up with a recovery key of 4889F7FD. I manually type the key and click the M: Drive which is the recovery OS. It says Error Recovering Disk due to no recovery key. I click Back and it comes up with a different recovery key as F9F25CA2. If both drives have the same password would the recovery key be the same. The bitlocker says I have temparary access but doesnt log me in.

When I go to safe mode, It loads half the files and comes up with the same. Start up recovery cant fix it. when I login to safemode, it loads half the files. Does this sound like a system wipe or can I fix this with a WIndows 7 Disc.

First off, Bitlocker has never been used on this computer. All its drives have never been encrypted. The problem is that when I open Bitlocker Drive Encryption in the Control Panel there are absolutely no drives listed at all. The area under the heading "BitLocker Drive Encryption - Hard Disk Drives" is completely blank, as is the area under "BitLocker To Go". However, Windows Explorer detects all hard and removable drives just fine.

I have tried the following:

1. chkdsk /r (no problems found)
2. sfc /scannnow (no problems found)
3. rebuilding the MBR with Comodo Cleaning Essentials (which didn't quite like the one I had) after aswMBR found no problem
4. repairing/resetting file and registry ownership and permissions to defaults using SubInACL scripts for registry and Tweaking.com for files. (This did fix a few minor nagging problems I had, by the way)
5. a clean boot
6. anti-malware scans (including several offline rescue CD's like Kaspersky, Comodo, ESET and AVG)
7. creating a new user account with admin privileges and trying from there
8. trying to trace file and registry activity with Sysinternals Process Monitor (but I don't really understand what to look for, or what most the results in the listing mean, good or bad)

A:Bitlocker Drive Encryption doesn.t recognize my password

Your harddrive doesn't only have a bitlocker password but bitlocker is also communicating with TPM chip on mainbord. And the mainboard has been swapped so you hav a new TPM chip with other secret key.

Didn't they check to see if it was bitlocker protected?
Do you have a backup? I assume you make backups prior to send your machine away

Hello,I am attempting to use BitLocker on my X61 Tablet ThinkPad but have run across an error message that is preventing me from initializing the BitLocker encryption. The message reads as follows: "Your system is not configured to use BitLocker Drive Encryption. If there is a bootable CD or DVD in your computer, remove it...if the problem persists, contact the computer manufacturer for BIOS upgrade instructions." I have run the BitLocker Drive Preparation Tool which has created its own boot drive (S and that program tells me that all is in order.  Additionally, I have verified that I have a fully updated BIOS.There is no bootable CD or DVD in the computer but there is what I assume to be Lenovo's Recovery software on a hidden and unalterable drive that appears in Disk Management. I cannot make changes to this drive; it is labeled only as"Healthy" and "EISA Configuration."Is this recovery drive the culprit that is preventing BitLocker from working? And if so, can it be disabled or BitLocker tricked into functioning while it is still present?Thanks for your help!Jay Fox

Has anyone ever heard of receiving the dreaded "Missing operating system" error after enabling BitLocker? Any ideas how to repair or work around this error?

The Backstory:

I have a Bitlocker-encrypted (TPM + pin) spinning 160 GB hard drive running Windows 7 SP1. Newly purchased, there is a 240 GB SSD drive sitting next to it, and my plan is to copy my whole partition from the 160 GB drive to the 240 GB drive and then enjoy a
faster computer.

First step was to fully decrypt BitLocker (took about 6 hours). Then, with the 240 GB SSD attached to my laptop with a USB adapter, I created a 240 GB partition, quick-formatted to NTFS, but did not assign any drive letter.

Next step was to boot the latest version of CloneZilla, and I did a partition-to-partition from the spinning disk to the SSD. Note that my original spinning drive did have a 300 MB partition for bootlocker - I ignored this partition and cloned only the Windows
7 partition. My reasoning was that the 300 MB Bitlocker partition may have drive-specific information that wouldn't work on the new SSD.

So with my partition cloning complete (about 1 hour), I swap the physical drives. My spinning 160 GB disk is removed and placed on the table, and my new SSD is inserted and screwed into the laptop. I restart - and boot directly into a Windows 7 install disk.
From that disk's recovery console, I run the automatic recovery option, which "fixes" a corrupt boot record.

With that comple... Read more

A:"Missing operating system" immediately after attempting to enable Bitlocker

I am familiar with those two specific messages, which are corrected by making the Windows partition active. I wouldn?t touch BitLocker until someone with a good knowledge of SSDs replies to your issue.
