Unable to start windows 10. Tried to System restore, system image recovery, startup repair, go back to the previous build, & reset this PC all did not work. Tried in "command prompt" chkdsk C: /f /r /x, but i get the error "The type of file system is RAW." "CHKDSK is not available for raw drives." I have tried to load raw drive recovery software via "command prompt", but it says the subsystem image is not supported. Please help!! Has anyone ever gone through this?
