  • Sure. Boot a Windows 7/8.x/10 Setup DVD or USB medium, then, instead of launching setup, press shift F10 and a command line will appear. There, you can mount the drive like that:

    manage-bde -unlock x: -rp yournumericalkey_here

    If that works, you can decrypt it like this:

    manage-bde -off x: -rp yournumericalkey_here

    (this will take a while and you can verify what it does by launching [on another shift-F10 prompt]

    manage-bde -status x:)

    The drive letter x: needs to be replaced for the letter as WINPE sees your drive. That can be found out again on the command line (you should do it before) with notepad. Start notepad by typing the command notepad and press strg-O and its open-dialogue comes up and you can navigate to "my computer" and see the drive letters.

  • Hi Rohan,

    According to the content of your post, I search related resources online, the error message you received seemed to be linked to McAfee rather than Microsoft.

    There is a similar case may be helpful to you, please check it.

  • Do you have a backup? You might need it :|

    I would undo the bitlocking and see if that helps. That can be done from winPE using the command line manage-bde.

  • Nope. I don't have backup. What i have is only bit locker key which I saved in pen drive while encryption.

  • I have the same situation as our friend Rohan555. We accidentally ran a Bitlocker on top of Mcafee Encryption and now the system is not Booting up. Same message "EEPC has been corrupted" is shown. 

    I have two partitions on this disk F: (System Reserved) and G: (RAW) but only one with Bitlocker signature (G:). System Reserved is accessible and ok. The RAW partition <g class="gr_ gr_96 gr-alert gr_gramm gr_inline_cards gr_run_anim Punctuation only-del replaceWithoutSep" data-gr-id="96" id="96">G:</g> is not accessible. 

    When I try to follow your instructions on G, I receive this message:

    ---------------------------------------------------------

    Trying to look for some answers<g class="gr_ gr_47 gr-alert gr_gramm gr_inline_cards gr_disable_anim_appear Punctuation multiReplace" data-gr-id="47" id="47">..</g> Any way to fix this Bitlocker</g> partition?

  • chbruno, make sure that the partition you are working with is really the one that is encrypted. I wrote before how to use notepad to identify that.
