BitLocker, TPM and a Ryzen

BitLocker encryption system drive password on bootup of course, just like on laptop, as mentioned + help me setting it up to not mess anything with TPM and so there will be a prompt for the password, on every boot.

I took a picture of UEFI TPM settings.








PS. Just seen that the system isn't Boot Secure.

 

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
