You're welcome Martin.


WindowsStar, I will test this later today to see if it can be done now without having to the preparation section as well. Hopefully it will no longer be needed.

WindowsStar,

I tried it again in a new Windows 7 installation, and it appears that you will still need to do the Preparation section to enable BitLocker on the C drive without a TPM. This is the message I got when I tried.

Hummm that is weird. I remember tying to install BitLocker and getting the same message but then later reading somewhere that MS changed it. So I tried installing and then it works....Another tech has been working on the machine too, maybe I need to talk to him.....Plus....I need to go check the BIOS and see if maybe it was disabled and I enabled it???? or he did??? ... UGH so many machines they all tend to blend together after awhile.

Strange. Have you checked to see if it may have been enabled via registry or GPEDIT already?

Hello Martin,

It may take a tad bit longer to load and save some items from the drive since it now has to encrypt and decrypt the file, but it's almost unnoticeable.

on a serious note, can i trouble you one last time Shawn? lets say that someone tries to access my computer without the key, when it reaches the "please insert key and press escape to reboot" screen, will it do any harm to the computer to do a hard power down?
