Bitlocker---Trying to get it installed

Have a "image" in SCCM.
We put the Win 7 Enterprise image on a bunch of craptops, and now we want bitlocker on them
The laptops have ONE drive (c:)

we try to run bitocker and it said we needed tpm...fine, we turn it on in the BIOS.
reboot and bitlocker runs, creates a key and creates a 300 meg partition but it goes no further
when we go into the TPM, the top two choices are greyed out.

we are just trying to do a "local" bitlocker with the key copy to desktop and a memory stick
Eventually we will use a server for that

Hi.

> ...bitlocker runs, creates a key and creates a 300 meg partition but it goes no further
What should that mean, where exactly does it stop, what message do you encounter?
> bitlocker with the key copy to desktop and a memory stick
Bitlocker without using a TPM can be done. Look at this: http://www.7tutorials.com/how-enable-bitlocker-without-tpm-chip-windows-7-windows-8

I guess the issue is that TPM is not initializing (greyed out)
this is local PC--not trying to use network setup or anything

Hmm... I wonder if Windows really does not tell you what to do with the TPM. Well, anyway, what about using the second option I described, the memory stick?

You did not read my link, did you?
In it, there is explained how to adjust one local policy and afterwards how to use the memory stick. No TPM needed that way. Read it, do it and you're good.

We actually WANT to use TPM, but just do it standalone for now for testing.
Note: it appears TPM is working


How do you set a "decryption" password?

The decryption is possible after the drive is mounted, no special password needed.
But why decrypt, let's first encrypt :)

When I used a TPM with Bitlocker on vista 6 years ago, all I had to do was activate the TPM and tell Bitlocker to encrypt, that was all. Could you please screenshot the last screen you see until your try to encrypt goes no further and upload it here?

WEll, I think we got it to encrypt :)  But we need a password on these to ensure the average user dosent de-crypt it.
Unfortunatley, because of some of our crap software, everyone needs to be admins...but that's another story.

Can we set a password on bitlocker to keep the user from de-crypting?

No, you can't. Admins can't be stopped here.

any way in group policy to lock it down to keem them from decrypting?
I don't believe that MS would allow anyone (even admins) to decrypt without a password...major security hole.

It is no major hole, come on... admins can format the whole disk, so why try to keep them from encrypting it? Admins need to be trusted. Not a single GPO would apply if admins wanted to.

Sorry, no GPOs for that.
