Windows 10: BitLocker encryption is enabled on your OS

***Modify title from: Trying to change boot configuration, but BitLocker prompts recovery mode - except I run Windows 10 Home, and don't have BitLocker installed?***


I am optimizing my Wintows 10 laptop by changing the boot settings to use all of my processors, not GUI boot, and a timeout of only 5 seconds.


However, when I click apply, this prompt shows up:





...Except that I don't have BitLocker installed and I run Windows 10 Home edition, which does not come with BitLocker. Why do I get this prompt? Is it safe to proceed? Will I lose access to my hard drive if I do so? If I DO have a recovery key, how do I find it and write it down into a safe place?


Thank you all for your help.

Not Able to Enable Hardware Based Bitlocker Encryption On Surface Pro 4 (Windows 10 Pro)

Ok, I have a feeling that this is a larger Windows 10 issue, but I am experiencing this with the Surface Pro 4, the ideal test hardware for anything Microsoft, right?

Here is what we are trying to accomplish:

Encrypt our Surface Pro 4's (win 10 Pro) using Hardware-Based Encryption

Why?

A) Because it is faster for the SSD to perform the encryption rather than the process, since the SSD is already encrypted

B) Better battery life (because the processor is not encrypting the volume)

C) Performing software encryption on an already encrypted volume defeats many of the internal optimizations that SSDs have built in (leading to slower performance)

How?

We have taken stock Surface Pro 4s, straight from the box. No applications or updates have been installed, we have not added to a domain. The only modification we have made is to the Local Group Policy:

Computer Configuration/Administrative Templates/Windows Components/Bitlocker Drive Encryption/Operating System Drives

*Require additional authentication at startup (Enabled, default options)

*Enable use of BitLocker Aauthentication requireing preboot keyboard input on slates (Enabled, default options)

*Configure use of hardware-based encryption for operating system drives (Enabled, default options)

What's Wrong:

When I go to enable Bitlocker, I am being provided the prompt to encrypt Used Only, or Whole Drive. From all of the literature I have read, this prompt indicates Software Encryption. When I select Full Drive, it takes a while (over 10 minutes) to encrypt.
Again, from my reading, Hardware

Encryption should be immediate (as everything is already encrypted).

Question:

What am I missing? Is there an issue with Hardware Encryption that I have not been able to identify on the Surface Pro 4? Is this an OS issue? Are there any other troubleshooting steps that I can take a look at? Again, these are stock units, fresh out of
the box from Microsoft.

BitLocker hardware encryption cannot be activated on Win10 10586/1511

Hey,

I'm having trouble enabling hardware encryption with BitLocker using Windows 10 build 10586 on a clean install with a Samsung 850 SSD. The encryption worked flawlessly before on build 10240.

I've spent hours and attempted multiple solutions and made several tests.

As mentioned, on the same machine, if clean installing build 10240 (RTM, before November update) right now, the encryption works.

I have UEFI on with Legacy/CSM off, Fast Boot on, Secure Boot on, and a clean GPT installation after using the 'diskpart clean' command.

As always, it's required to change a group policy to allow additional authentication at startup. I did that.

On a clean installation of build 10586, the wizard will say 'parameter is incorrect' when attempting to start encryption.

Microsoft did announce some BitLocker-related changes for build 10586: https://technet.microsoft.com/en-us/library/mt403325

There are also new group policies added. I've tried all combinations. They now allow you to try and force a specific encryption cipher. Samsung uses XES-AES256. I tried forcing that (as well as all other combinations) but the same error returns.

Now, here's where it gets interesting, and possibly why no reports about this have surfaced yet:
If you enable the encryption on build 10240, and then upgrade to 10586, the encryption will remain and will work properly on build 10586.

If you then attempt to 'Reset this PC', and choose the 'keep nothing' option, it will warn you that BitLocker will be disabled. Once it's done cleaning, if you attempt to enable encryption, it will again show the error.

Even if you don't reset the PC, but simply disable BitLocker on 10586 and then attempt to re-enable it, it will no longer work.

tl;dr: Hardware encryption via BitLocker on build 10586 cannot be enabled on a clean install. Currently-known workaround is installing 10240, encrypting it, then upgrading to 10586.

Any solutions would be appreciated, thanks!
