Didn't work , nothing changed still only black screen appear with only the arrow pointer . Please help me to out of this issue . 
- Type BOOTREC /FIXMBR, and then press ENTER.
- Type BOOTREC /FIXBOOT, and then press ENTER.
- Type BOOTREC /REBUILDBCD, and then press ENTER.
NOTE... If you have multiple HDDs\SSDs, it would be best to unhook all except fro the OS drive..
If available, you might select "Startup Repair" before attempting the BOOTREC commands...
