I don't get those options.
well I guess we can assume your setup differs from mine.
I have setup bitlocker without any self entered password, excluding the tpm module. I use the bitlocker generated .bek file(hidden) on a usb, temporarily, just in case, during setup.
when encrypting c: bitlocker asks to save the key to a file, etc., etc. I point to the usb and bitlocker send the .bek(hidden) and the 48 digit recovery password text file. I do the same for d: & e: with the exception that I check off the box that allows automatic unlocking with c: the only password I've entered is for my windows account. as far as I know, while at my open desktop, locking e: (inaccessable) separately, from the desktop, is incompatible with automatic unlocking. terms like, turn off, disable, suspend mean different thing depending on the current state.
I copy my key files to a second usb and encrypt one with bitlocker and one with truecrypt using my own password.
if you mess with the bios you'll get locked out so suspend protection beforehand, reboot and resume. some software seems to have access to the bios, i vaguely recall it as such but if you find yourself locked out, go to the notebook pc or secreted hardcopy and get the 48 digit key. then suspend reboot and resume.
