Windows 10 bitlocker protected drive is not working.

Hi,

Detailed Case Information:
I have Windows 10 and BitLocker enabled.

HDD, Seagate 3TB, partitioned into 5 drives.

I did this mistake, I created a bootable USB by easy bcd and tested on host window during boot. Reached to the point where windows setup asks for disk selection, I clicked on the drive(setup says drive encrypted and can't continue) but didn't go further.

Then I boot nothing shows up.

Tried to connect 3tb hard to another PC to unlock drive but it's not accepting correct password and recovery key.

I made windows image before encryption. After restoring that 2nd and 4th drives are not accessible, 5th is formatted and 3rd drive data is intact with minor data loss.

I ran testdisk-7.0 and found no drive in the quick search. The log file is pasted below.
