Macbook pro i7 mid-2014 boot issues (loop)

My mackbook pro is stuck in a boot loop. After restarting, when i put in my password, it shows the loading bar, but half way through it reboots.


Things I have tried:

  1. Reseting the pram and nvram
  2. Safe mode does not boot up as well
  3. using a usb boot disk (with Mojave 10.14)


Even with the usb boot disk, the laptop begins to load the OS but then just restarts.


Any ideas on how to resolve this and what the problem might be?


Operating System: High Sierra 10.13

You can try Boot into Internet Recovery (Option Command R) and from the dropdown menu: Utilities>  Disk Utility> run the First Aid on your Macintosh HD (and the "Macintosh HD-Data" volume as well if Catalina/Big Sur) If errors are found and repaired, run again until no errors reported.


Disk Utility>View>Show All Devices The best sequence is —

• Volume level

• Container level

• Parent drive
