Windows Central Question
My laptop goes from the "toshiba" screen directly to "undoing changes; do not turn off computer" and stays there for hours. I am unable to get into safe mode. The only screen I have been able to get into is using the shift/F10 screen which goes into automatic repair then it tells me that it could not repair. I can choose "restart" or "advanced options". When I choose "advanced options", my options are "continue (exit and continue with windows 8.1 which goes back to the beginning), "use a device" (I don't have a recovery dvd and I can't go online to download anything. Do you have any advice to offer to fix this?
