Specs: Windows 7, i7-2670QM-8CPUs/8GB RAM
Hi again. Whenever I try to turn on Bitlocker on any driver I get the error
"A compatible Trusted Platform module (TPM) Security Device must be present on this computer, but a TPM was not found"

I think that Vostro 3750 supports TPM It's probably just my OS. When I want to try to encrypt my drives without TPM support going to ''gpedit.msc'' -
"Computer Configuration \ Administrative Templates \ Windows Components \ Bit Locker Drive Encryption \ Operating System Drives and double click on Require additional authentication at startup."

There is no ''Require Additional Authentication at startup'' option... The option isn't there.

✔ Best Answer
If you have a TPM, you'll have to enable that in your BIOS.

NOTE: You have to have Windows 7 Professional, or above, to use bitlocker.

It matters not how straight the gate,
How charged with punishments the scroll,

I am the captain of my soul.

I have A12 BIOS is that the latest for Dell Vostro 3750? I don't think the option is inside F2 BIOS options at startup... I cannot restart now, cause I'm uploading to Comodo Cloud.. I wonder why don't i have that gpedit.msc option and I'm afraid to use that option without OS detecting TPM anyways.
Also I have reinstalled OS recently does that also delete BIOS update files or some of it? It still shows A12 but I'm afraid after OS formation and reinstallation some files might be missing for BIOS no?

OS and bios are separate. The bios contains no files on the hard drive.

Might want to consider Truecrypt.

I didn't find option that says anything about TPM in BIOS.
