Update to Windows 10 failed.
I have been troubled with this one for a while. My tablet was updating to Windows 10 (while plugged into a ups) and failed. Actually received a failure notice. Now upon booting it will make it past the post screen (the bios and recovery menus too) but will not display anything past that. The cursor will show up on the screen when using the track pad or digitizer but will not do anything else.
When booting into the recovery menu all options say that I need to sign in as admin but cannot find any accounts on file. I try resetting the tablet but it errors out at 66%. I have attempted to roll it back to 8.1 but that fails as well. As does trying to load another OS file from bootable usb. At a complete loss and would like to avoid replacing the motherboard just to get it up and running again.
