    It's up to you if you feel that you need the extra access security it provides. I like using a USB flash drive, but the password option is good as well.

    If you decide to do so, be sure that you back up the BitLocker recovery key and startup key. If you get locked out of the drive by BitLocker and do not have these keys, you'll be completely out of luck on trying to access the drive again.

    bitlocker on yoga 2 pro


    i want to encrypt my yoga 2 pro [y2p] system running 8.1.

    i tried to boot a kali linux thumbdrive on it to see if the y2p could boot from it. i discovered it would not boot from the thumbdrive by default; I had to make an /EFI/Boot folder on the thumbdrive and add some files to it (https://forums.kali.org/showthread.p...all-Kali-Linux) for the Y2P system to be able to see and try to boot from the USB thumbdrive.

    this has me worried about trying to use bitlocker on the Y2P; worried it wont be able to use the thumbdrive to unlock the encrypted drive because bitlocker doesn't support EFI systems? (Windows BitLocker Drive Encryption Frequently Asked Questions).

    i'm terrified of trying to enable bitlocker on this thing.

    btw - im not insistent on using a usb key for bitlocker; i'd actually prefer to use a passphrase.

    doesn't seem like Y2P has a TPM chip (https://forums.lenovo.com/t5/Idea-Wi...p/td-p/1298457).

    another related link: ***Yoga 2 Pro Owners Thread*** - Page 75

    and another: bitlocker - Lenovo Community

    i feel like this is way too difficult or i am missing something simple here.

    what should i do? any advice?

    thanks in advance all!

    Hello Devios, and welcome to Eight Forums.

    The Microsoft article you referenced for BitLocker was for Vista instead. The BitLocker in Windows 8 and 8.1 will work just fine with UEFI, so no worries there.

    You should have no issue using either a passphrase or USB, but I would recommend to keep a backup copy of the BitLocker startup and recovery key in a safe location should something happen to the USB or you forget the passphrase, and easier if you should ever need to recover the drive.

    It does seem difficult, but it's really not once you give it a try and get used to it. Once you do, it almost no different then signing in to Windows, but just more securely.

    Encrypting with BitLocker will either be successful or fail, but you shouldn't have any issues while doing the steps exactly in the tutorial. If it fails, then no harm no foul since nothing would have changed.

    Please feel free to ask any questions you may have.

    thanks brink - i couldn't seem to find any link where microsoft (or anyone else) states bitlocker works fine/easily/completely on 8.1 UEFI systems without a TPM chip. do you have any such link(s)?

    either way, i'll give it a shot when my new usb thumbdrives arrive and let forum know how it goes.

    No worries. A TPM is not required for UEFI in Windows 8/8.1.

    That documentation example isn't super clear. Where do they find the monkeys that write and edit the MS documentation?!

    For the record, happy to report that after making the policy change to allow bitlocker on a machine without a TPM chip, I was able to encrypt my C:\ (system) drive using BitLocker, and was allowed to chose to use a passphrase or USB key to unlock on boot. I chose password, and it's working great on my Y2P.

    Thank you again for the help and information!

    You're most welcome Devios. I'm happy to hear that all went well.

    Yeah, some of those documents can be a bit cryptic at times. Pun intended.

    Hello to everyone,

    I want to know ... Will this work if I have installed TPM chip in the laptop but if I want to encrypt the OS drive without using the TPM chip ? ( to check "Allow Bitlocker without a compatible TPM" ) The laptop is with Windows 8.1 and I don't want to manage ( administrate ) the TPM chip

    Hello Stilcho,

    I don't have a TPM to test with, but you could give it a try to see if you may be able to select not to use the TPM.

    If not, then you may need to either disable or remove the TPM chip if able first to be able to use OPTION ONE to use BitLocker without the TPM.
