Windows 10: 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.

Bit Locker disable problem

To my knowledge Bitlocker is compatible on all Windows PCs. Exception: If you protected a drive with the new Bitlocker encryption on Windows 10 then you cannot unlock it on a Windows 7 PC. I can open my Bitlocker protected drives on other Windows 10 PCs.
But I choose to protect them with a password since I don't have the TPM chip in my PCs and I use
Bitlocker to Go for removable drives.

When you are finished with a drive protected by bitlocker you don't lock it before powering down or removing it. Bitlocker is not available on Windows 10 Home so maybe you can't open it on a Home edition PC (not sure about that).

This is a good reference:
