    Do I need to decrypt non system drive before reinstallatio


    i have my D and E (non OS drives) encrypted with bitlocker in windows 7.it uses password to unlock drives.OS is in C drive.now i am going to install windows 8.
    I am gonna do a clean installation means completely formatting C drive. the data i am worried about is in encrypted D and E drives by bitlocker.so do i have to decrypt the D and E drives first.im worried cuz bitlocker is a program of windows 7 and when i format C drive means windows 7 gone means windows 7 had the bitlocker program which encrypted the D and E drives and now its windows 8 installed in C drive .so how would windows 8 respond or know what my password was when it was created in windows 7

    P.S I dont wanna decrypt drives because it takes hell of a time but i also dont wannna risk losing my data...!!!

    Hello Waqas,

    If you have the BitLocker Recovery Key available to use, then you will be good to go to leave them encrypted.

    After installing Windows 8, it may ask you to enter the BitLocker password (if used) or recovery key to be able unlock them when you try to open them.

    If needed, you could also use the tutorial below to recover the drives.

    Hope this helps,
    Shawn

    Thanks for quick reply bro
    I know the passwords for both drives but i dont remember where i saved recovery keys.so after installation it might ask for recovery key instead of password and i wont have that..so i think i ll have to decrypt the drives first.
    Now what do you think

    Decrypting the drives would certainly be the safest and most reliable route, then just decrypt them again after Windows 8 is installed. To bad it would take forever to do so though.

    You could use the method in the tutorial below to backup your BitLocker Recovery Key for each encrypted drive to say a USB flash drive to have available to recover them with if needed in Windows 8.

    Personally, I would recommend to just decrypt them. Best to be safe than sorry later.
