Go to your registry type in Bitlocker, disable the Bitlocker about four in a row going down. Reboot your computer and wha la, u have disabled bitlocker. Now when Windows boots up repair what files that are corrupt. Pretty easy when you are going to install new Windows, as a matter of fact if you installed Windows 10 use your original windows to complete the bitlocker registry disablement, pick install a driver, or image, which ever one pulls up Windows Security power shell, also you will be able to reformat your operating system drive. Rename the drive OS (?)...
Currently it's set to Manual start, and it's not started, yet I am being prompted to backup my key. I'll set it to disable and see.
Anything else to check on? – Pat – 2012-01-26T15:11:34.247
It's been a while, and it hasn't happened, so I'll mark this complete. – Pat – 2014-02-24T00:27:41.157
