I have a windows 8 Toshiba Satellite L875-S7377, and it has recently been stuck in a loop. It won't boot past the toshiba logo screen. When I turn on the power, the toshiba logo shows up, and in about 7 seconds, I see the "Your PC ran into a problem... UNMOUNTABLE BOOT VOLUME." Right after, the Toshiba logo appears and it start 'Preparing Automatic Repair,' and hits a black screen for another 10-20 minutes just to hit the same 'UNMOUNTABLE BOOT VOLUME' error and the process repeats.
I've tried many different solutions from going into safe mode (which I can't open), creating a USB boot drive with a windows 8.1 iso burned in (which didn't have any effect at all), and powering it off and back on. I don't have the funding for a new PC yet, and I would really like to continue using this Toshiba laptop.
Pressing the keyboard and sticking a bootable USB are ineffective and I don't have a Microsoft repair disk, so what should I do? Should I take out my drive and wipe it clean on another PC, or is there any other option without opening the laptop?
Thank you.

5. Answer Y to check the disk the next time that the system restarts.
6. Reboot the system. After the reboot, Windows will check the hard disk and try to repair the damaged area.
7. If you still get the error after this process, repeat the process but try rebuilding the master boot record at the command prompt with the following command: bootrec /fixboot and then rebooting

It's possible that your USB drive isn't burned correctly ( to boot from ) or you are trying to boot from the USB 3.0 port, in which case, that model has 1 USB 2.0 port that you would need to boot from.
or, if you MUST try to boot the USB from USB 3.0 you will need this:

and download the correct one for Windows 8.1

if NONE of these options work, you more than likely have a failed hard drive and will need to replace the drive and reload the operating system.
