Unable to capture image - Bitlocker Signature detected
-
Hi,
I’m trying to capture a Windows 10 image to the FOG server. On the Windows 10 client, I’ve disabled bitlocker and run sysprep, but the capture process keeps getting stuck with the error: “Found bitlocker signature in partition /dev/sda3 header. Please disable BITLOCKER before capturing an image. (isBitlockedPartition)”
I’ve verified that Bitlocker is off on the drive and it is decrypted, so I’m not sure why the capture process keeps getting stuck. Any help would be appreciated.
Thanks!

@jramos76 Please run
manage-bde -status C:in an Admin cmd window to see if Bitlocker is really disabled on this drive.Found bitlocker signature in partition /dev/sda3 header
Hmmm, maybe it’s not
but a different partition? Try the above command with different driver letters if you have more than just -
@Sebastian-Roth - I’ve run the command and it says the C drive is “Fully Decrypted” and Bitlocker Version: None. When I look at the partitions on the machine, I see (Disk 0 partition 1) is the EFI System Partition and OS (C:) as the (Boot, Page File, Crash Dump, Primary Partition).

@jramos76 bitlocker is a bit weird as it will encrypt freespace sometimes
I think the command to fully turn off bitlocker is
manage-bde off c: -
@jramos76 If the command Tom provided still doesn’t solve the problem we’d need to have a closer look at the partition layout. Please schedule a debug capture task for this machine (as you would a normal capture task but just before you hit the button in the web UI there is a checkbox for debug mode), boot up the machine and hit ENTER twice to get to the console. Run command
sfdisk -d /dev/sda, take a picture of the output and post that here. -
@Sebastian-Roth - Here is the output of the command.

Looks like the image is not uploading. I clicked “Upload Image”, but it gives me an error. Any other way to upload the picture?
-
@Tom-Elliott - thanks for the command. I did verify that bitlocker was turned off on the
Drive using the command that @Sebastian-Roth provided. I tried uploading a picture from the debug command, but I don’t think it went through. I’m hoping I can get the picture to you another way. -
@jramos76 Sorry about the picture upload issue. The forum is a bit picky with that and it breaks every now and then. Could you please upload the picture to some share platform and post a link here?
-
@Sebastian-Roth - Thank you for your help with this. I had to disable TPM in the BIOS for the Bitlocker message to go away. Now I have another issue. It goes through capturing the image, but at the end, it says “Could no complete tasking (/bin/fog.upload)” and it has “Error returned: Invalid Storage Group” listed many times above.
-
@jramos76 I understand what the status returned but did you try turning off bitlocker implicitly as I described? There is a reason I gave the command. I think, it too, would have helped. And you wouldn’t have had to disable the TPM.
Glad you found a fix either way there.

@jramos76 Good you found a way around the bitlocker issue. I’ll mark this topic solved. May I ask you to open a new one for the next issue? We try to keep things sorted for others to find help in the forums quickly too. Please post the version of FOG you are running in that new topic as well.

@Sebastian-Roth Thanks Sebastian! Will do!

@Tom-Elliott Hi Tom, sorry, I didn’t reply with that info, but yes, I did run the command you suggested to explicitly turn off bitlocker, but it was still giving me the same error. The error only went away once TPM was disabled in the BIOS. Thanks for your help trying to figure this out!
