WIN8 system repair for boot encryption in Windows to go mode

This is a creation in Article, where the information may have evolved or changed.

Win8 X64 Enterprise Edition, the system blue screen prompt "Inaccessable_boot_device", do not want to reload, security mode is not in, so try to use System disk system repair, but in the repair when prompted to say that the system disk is encrypted, need to be unlocked before you can repair

So, first:

Then enter the password to unlock and then remove the encryption:

Manage-bde-off C:

Prompt decryption in progress, and then came back, instead of showing the progress bar, I thought it was done, so I quit, the result of repair or prompt is not unlocked

Then think of should use status to look at, then re-step above, and then prompted the decryption in the end of the process, so that:

Manage-bde-status

Sure enough to see, or "transition state" is the decryption in progress, so wait;

Just don't know how to use it directly

Manage-bde Autounlock

Yes, No.

And then find out, no, read the log, prompt

Unknown detection error: Detection error 7e. Parameters = 0xffffffffc0000005, 0xfffff880010d603f, 0xfffff88002f96008, 0xfffff88002f95840. Repair operation: System Restore Connection Ugo: failed. Error code = 0x1f Use time = 89406 ms FIX: System file integrity check and repair result: failed. Error code = time used by 0x57 = 3891 ms

The result seems to be no solution, but the system started, found that BitLocker boot password is gone, the system can get up, do not understand!
