Bitlocker Questions

Thanks. I am going to now do step 7 which will take a while to encrypt.

I skipped step 1 and just stick with the default 128 bit security like I did previously.


Did step 4.


Now when I do step 6... which tells me to do step 7, 8 or 9 which is essentially the same step of turning on bit locker...


I get this message


This pc requires a startup option that isn't supported by bitlocker setup. Please contact your system administrator to turn on bitlocker.


Why do I have this message?

Does this message has something to do with my user accounts or something?


I see in user accounts


My name
local account
Administrator


I checked online that in user account, an account is either a local account or administrator. But mine is both or is it local account?


So why can I not turn bitlocker on?

So I tried the 3 different ways to get to the local C drive. In the first way of just going to my pc and then going to local disk c drive and then right click on turn bitlocker on... i get that message i mentioned above.


Now when i just type go to start menu and type i bitlocker, it shows manage bitlocker so i click on that...


It shows c drive: bitlocker off... next to it is Turn bitlocker on and when click on it... same message


Below it does show the words


Fixed data drives


Removable data drives - Bitlocker to go
Insert a removable usb flash drive to use bitlocker on the go



What mistake am I making here? Is it an admin thing or is it something else? You mentioned in step 4, to make every allow to REQUIRE... so im not sure why im getting this message?
