Lenovo Yoga SSD based. No integrated CD/DVD. 16 GB memory, Intel i5 or i7 (don't remember). System will not boot. Error is a xc00000a2. System fails to "fix" issue. Have gone to "advanced options" and am attempting to get to a Command Prompt which shows "Owner" in the owner block. Clicking OK takes me to a PW screen which we do no have or know. As far as I know, this password has never been set. Is there a way around this PW or another technique for using a command prompt to do SFC or dskchk or several of the other options to find the likely corrupted driver or registry entry or damaged system file? I have not tried a system reload since I would prefer to preserve installed programs.
Are you the original purchaser of the system?Check Lenovo support for default ..
Pull the SSD and clove it.
Use USB media installer to boot the system and see whether you can confirm whether the issue resulted from a failed update.
