After an update suggested by DELL, my computer could not reboot due to a bitlocker problem. Following the instructions, there was only one possible solution and that instructed the computer to save apps and files to a hard drive, and then erase and redo the computer. Unfortunately, something went balistically wrong and now my computer will not restart. The computer simply shows the DELL logo on the screen as if it is trying to reboot and never does. Now I am unsure what to do. I am also at a loose at what to do with the backup .mig files. Unable to access them or extract the files from them. A total stessful situation.
