Bitlocked "Windows 8 To Go" failed

[admin]

I've just tried "Windows To Go Upgrader" on a bitlocked version of "Windows 8 To Go", but after entering the Bitlocker-Key I was getting a blue screen. Do I first need to decrypt "Windows 8 To Go"? (Afterward "Windows 8 To Goo" hardly booted up again ....)

Windows To Go Upgrader does not directly support upgrading the Windows To Go drive which has been encrypted with BitLocker, so please turn off BitLocker drive encryption on the drive and try again.

If it still failed, please tell us more infomation about the BSOD, such as the error code. If it is possible, please take some screenshots and send it to us.
Thanks.

It appears, however, that there is some issue with "boot.vhd", because inside the "VirtualBox Manager", "boot.vhd" is "not accessible". That can't be right!?

Could you take a screenshot and send it to us?
Thanks.
