# You may try in safe mode as mentioned earlier by others # Best advise is to take the system to apple care, or reinstall OS X from scratch # If the diskutil fails to repair and mount disk0, chances are your disk is partially or completely corrupted # Clean HS installation is only possible if the partition map is successfully verified Try the HS installation after the disk is successfully repaired If the disk gets mounted, or the repair is successful, type 'restart' and hit return If the Error: -69842: Couldn't mount disk still persists, you may try command 'mount force /dev/disk0' If the Error: -69842: Couldn't mount disk continues to show up, try the command 'mount /dev/disk0' (without quotes) If any error gets detected, type 'sudo diskutil repairdisk disk0' and press 'y' (you must have total backup before this) Open Terminal, and type 'sudo diskutil verifyDisk disk0' and check for any boot error (type password at prompt) Temporarily you could Turn Off File Vault from system preferences > security and privacy > File Vault > Turn Off You may check to see if your disk is unencrypted.
