If you want something to do the same as Bitlocker and you have windows 7 workstations then, silly question I know, why not use Bitlocker?  You dont explain why you can not or dont want to use bitlocker.

I recommend DiskCryptor. It's open source/free and the code can be inspected.
It's kept up to date and there is a support forum.
It has exactly the feature you are looking for (Storing the decryption key on a flash drive)

From the website...
Option to place boot loader on external media and to authenticate using the key media.

Truecrypt is still available for download and I think it supports the usb feature.
Unfortunately it is no longer supported.

Bitlocker is only available on Windows 7 Enterprise and Windows 7 Ultimate
and ITMaster1979 only has the Pro version.

besides .... I wouldn't really trust bitlocker with commercially sensitive data
I'd bet that there is a built-in backdoor ..... search for yourself.

OK, i missed the Pro bit.

As to a backdoor....

There is no proven backdoor to bitlocker unless your an apple fan or a microsoft hater and then of course there are aliens on the moon and Elvis works in a chip ship.

Seriously though, there is no proven backdoor, only the normal conspiracy theorists spreading rumours. Same as Truecrypt.  Still nobody has a proven backdoor or exploitable code for it but thats what everyone thinks.

I'm a Snowden fan and highly suspicious of the NSA.
but you are right ... the case has not been proven.

Case proven.... You have your opinion based on the media.
