After Apple Update, unbootable startup drive

[flashg8228]

I recently installed a new SSD about a month and a half ago and everything was working great. I followed the instructions I received here and everything was fine. I installed an Apple update about a week ago, before doing so I disable TE, re-enabled kext, installed the update, turned TE back on, disabled kext and everything was fine. I followed the same procedure for the most recent Apple update that came out this week and now my MBP won't boot up. I have the USB that had the original OS X installer on it and am wondering do I just have to reinstall OS X from the USB and go from there? Or is there something else I can do to be able to reboot. Any and all help would be greatly appreciated. Thank you.

Just reinstall OS X from the USB. Your files will remain there as long as you don't go to Disk Utility and erase the drive.

And I just do that by holding down the option key after the chime and go from there?

Yup.
