when booting with this error, usually indicates file corruption. this could be because of faulty hard drive or just corrupt system files. two options for repair would be to start into recovery mode…press f8 at boot up and go to the command line prompt. from there you can run sfc /scannow and chkdsk /f this will attempt to fix and repair any system file corruption and bad sectors on your hard drive. if this does not fix your boot issue, you will want to do a smart disck check, also in your recovery menu. if this fails or is taking a long time to complete, you will want to change your hard drive. hope this helps. post back for any further assistance.
