Windows 10 and bit locker

I have a Dell Venue 8 pro tablet with windows 10. I am not too sure what happened but it is stuck in a diagnostic loop. I have tried to reinstall windows but have run into bit locker. I have not used bit locker not have I ever enabled it. I cannot
access the control panel to disable it, I have gone the bit locker recovery key routine and still am unable to get anywhere on reinstalling windows. Install is telling my that it cant use my c drive because of bit locker and to go into control panel to
disable it. I am also unable to perform any kind of repair. the message is that there is a problem and tells me nothing else, chkdsk shows errors but says the disk is write protected (?) . I am kinda stuck on this one

 

Bit locker Encryption

Hello Fiends,

Actually my problem is that i have previously installed windows 7 ultimate(32 bit) in my desktop and to protect my data,
encrypted the "D drive" using bit locker, then after few months, i installed
windows 10 pro(64 bit) in my desktop without disabling the bit locker, after installation i was able to access my locked drive with same password.

Till here everything was fine, but after some days my Desktop started to lag then again i switched to
windows 7 ultimate(64 bit).

But Now i'm not able to access my encrypted drive which was locked by bit locker with same password.

While i'm trying to unlock the encrypted drive i'm getting the massage as
"Unable to Complete the requested operation because of either a catastrophic media failure
or a data structure corruption on the disk".

Pls Help.

Thanks.

 

bit-locker decryption

i am a windows 10 user and i clicked the bit-locker icon for my WD HDD. Without giving any password, i cancel that window by the cancel button. But now it shows locked with bit-locker and i can't access the data and i can't format too. Also it can't unlock
from bit-locker manager. What is the solution to access the HDD.
