Windows 10: BitLocker, TPM and a Ryzen

I simply love the BitLocker functionality. I've always used it and still using for my Intel laptop without TPM, but with a small change in Group Policy to skip TPM and use a password on every boot... and it simply working.

Hovewer, now I've a AMD PC with Ryzen 1700x onboard. I've noticed that the TPM comes free to these CPUs. How to set this thing properly along with BitLocker encrypted system drive? Help needed as I can't figure out the correct UEFI settings, along with Group Policies rules changes, if they're needed to be changed. I've tried to encrypt the system drive (with out of the box UEFI settings), after first Windows installation, but the system booted up without password prompt which I'm for, before every bootup, just like on the laptop.

So, I've played a bit with Group Policy rules and UEFI settings, but still couldn't manage the password prompt. Re-encrypted the drive without any result, discovered a new TPM menu in UEFI, played a bit more with changing settings here and there and stopped. It was on 1809.
How to reset this thing completely without losing or need of Windows re-installation? I've installed 1903 last week so the system isn't protected now, and I haven't touched Group Policy on it. I've updated the BIOS and maybe TPM settings has been reset to default? I can't sleep without securing my data and I don't want to eventually mess up anything this time with a lot of changed settings on a fresh system *chuckle

How to set it up? Below you can see how it look for my motherboard. ASUS X470 STRIX.

TPM Device Selection is set to Firmware TPM
Erase fTPM NV for factory reset is set to Enabled






I can't tell you the extra UEFI TPM menu since I don't know how to take a printscreen of UEFI? Anybody?

I understand that TPM is used to link all(?) devices together and encrypt them so I can't switch any device before resetting TPM with a key? Or is it just processor specific anti-theft thing?

Thank you in advance.

Bitlocker without TPM

Hi there,

I'm trying to use Bitlocker without TPM

My version is Windows 10 Home, and I try to follow -

To turn on BitLocker Drive Encryption on a computer without a compatible TPM

1. Click Start, type gpedit.mscin the Start Search box, and then press ENTER.
2. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.
3. In the Local Group Policy Editor console tree, click Local Computer Policy, click Administrative Templates, click Windows Components, and then clickBitLocker Drive Encryption.
4. Double-click the setting Control Panel Setup: Enable Advanced Startup Options.
5. Select the Enabled option, select the Allow BitLocker without a compatible TPM check box, and then click OK.

You have changed the policy setting so that you can use a startup key instead of a TPM.

1. Close the Local Group Policy Editor.
2. To force Group Policy to apply immediately, you can click Start, typegpupdate.exe /forcein the Start Search box, and then press ENTER.
3. Click Start, click Control Panel, click Security, and then click BitLocker Drive Encryption.
4. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.
5. On the BitLocker Drive Encryption page, click Turn On BitLocker. This will only appear with the operating system volume.
6. On the Set BitLocker Startup Preferences page, select the Require Startup USB Key at every startup option. This is the only option available for non-TPM configurations. This key must be inserted each time before you start
   the computer.
7. Insert your USB flash drive in the computer, if it is not already there.
8. On the Save your Startup Key page, choose the location of your USB flash drive, and then click Save.
9. On the Save the recovery password page, you will see the following options:

· Save the password on a USB drive. Saves the password to a USB flash drive.

· Save the password in a folder. Saves the password to a folder on a network drive or other location.

· Print the password. Prints the password

While I have a problem on step 4.

Double-click the setting Control Panel Setup: Enable Advanced Startup Options.

I can find "BitLocker Drive Encryption" on my group policy editor, while I cannot find
Control Panel Setup: Enable Advanced Startup Options anywhere.

Thank you for your help.

Best Regards,

Yan

According to here you need to boot in UEFI to configure bitlocker then you can change to CSM.
