Can’t resume decryption Bitlock

Question

Can’t resume decryption Bitlock

Jonathan Macias 0

Hello, I bought a Lenovo legion go 2 a couple days ago and wanted to dual boot my device but I can’t do partition because my drive is BitLocked, I tried turning off bitlock but after a day it was stuck at a percentage and tried to pause it and resume the progress manually on cmd as an admin but it didn’t let me resume anymore and now I’m stuck. I tried so many things I even reset the device and nothing works.

Hi Jonathan Macias,

I understand how frustrating this must be, especially after resetting a new device and still being unable to prepare the drive for dual boot.

The error in the screenshot indicates that Windows still considers drive C: to be in the encryption process. Because that operation has not finished, BitLocker cannot start decrypting the drive at the same time.

Before making further changes, please make sure your BitLocker recovery key is backed up. Then, open Command Prompt or PowerShell as administrator and run: manage-bde -status C:

Could you share the results for Conversion Status, Percentage Encrypted, Protection Status, and Lock Status? Please remove any personal or recovery-key information before posting the screenshot.

If Conversion Status shows that encryption is paused, run: manage-bde -resume C:

Keep the device connected to power and allow the encryption process to finish. Once the status reaches Fully Encrypted, you can try turning BitLocker off again with: manage-bde -off C:

Please avoid repartitioning the drive or installing another operating system while BitLocker is still converting the volume, as this could put the data or recovery process at risk.

I hope this helps get the BitLocker process moving again. If the issue continues, please share the output of manage-bde -status C: after removing any personal or recovery-key information, and I can take a closer look at the current drive status. Thank you so much for your understanding.

It won’t let me resume the decryption because it says it’s being encrypted. It’s been like this more than 24 hours and encryption hasn’t fully completed even though I never encrypted the drive

Hi Jonathan Macias,

Thank you for sharing the status output. It provides a much clearer picture of what is happening.

The result shows that drive C: is currently 54.8% encrypted, with the Conversion Status listed as “Decryption Paused.” However, Windows is returning an error stating that the drive is being encrypted when you try to resume it. This means the BitLocker conversion state is not responding as expected.

Device Encryption can sometimes be enabled automatically during the initial setup of a new Windows device, even if you did not manually turn on BitLocker.

Since the status has remained unchanged for more than 24 hours and both manage-bde -resume C: and manage-bde -off C: return the same error, I would avoid repeatedly running additional BitLocker commands, resetting the PC again, or attempting to repartition the drive at this stage. Please also make sure that the BitLocker recovery key and any important files are backed up.

As this appears to require a closer review of the BitLocker service and the drive’s conversion state, please contact Microsoft Support and provide the following information:

The error code 0x803100d6

The manage-bde -status C: output

The fact that the status has remained at 54.8% for more than 24 hours

The device model and confirmation that it is a newly purchased device

When the Support Assistant appears, you can enter: “BitLocker decryption is paused at 54.8% and manage-bde -resume returns error 0x803100d6. I need to speak with a live support agent.”

Because this is a recently purchased Lenovo device, you may also contact Lenovo Support if Microsoft Support identifies a storage, firmware, or factory-configuration issue.

For now, please do not create or resize partitions until the BitLocker conversion state has been resolved. I hope the support team can help restore the drive to a consistent state without affecting your data. Thank you so much for your cooperation.
