Well now at start up when I hold down option i'm somewhat able to boot into windows expect when I do I get a error message that says "A disk read error occurred, press Ctrl+Alt+Del to restart" Pressing those keys won't let me restart either I even tried on a standard logitech keyboard for windows. Also in disk utility bootcamp is still greyed out/unmounted and labeled as disk0s3.

How do I run startup repair I'm not seeing anything in finder. I don't think I have any third party NTFS software installed. I do have the Stellar Phoenix Data Recovery app but that's only for recovering data from faulting drives.

That's another issue I've had since I installed bootcamp for the first time. The volume never appeared. I've tried over and over again to get the BOOTCAMP HDD to appear and it never has.

I've tried that and only the mac partition is showing up. The only modifications made was installing the 2TB HDD. The reason for this was because I was using Bootcamp before on the stock 750 gb hdd and I needed more room for windows and I didn't want to compromise the hd space of the mac partition. So what I did originally was remove Bootcamp then copy the mac partition over to the new hard drive. Everything was working fine. Afterwards I made a new partition for windows and tried installing bootcamp. I had some trouble at first getting it to install but I got it to work and everything was running great. The only change I noticed was Bootcamp HDD wasn't showing up no matter what I did but I never thought that was a big deal anyway.

When booting up my macbook gives me two to options to choose to boot from. One is "Windows Installer" (Not Bootcamp) & the other is "EFI Boot". I tired start up repair from both and right after I get the message "windows is diagnosing your computer" it immediately restarts and nothing changes. The article from that link you posted says to try another step if start up repair doesn't work but I'm not sure if I should boot into the windows installer or the EFI boot before I do that.

I want to say yes. Windows was installed using EFI boot because as mentioned before I ran into trouble using the regular installer. I've had bootcamp installed on my MBP 4 times. First when I bought the MBP I installed bootcamp but quickly removed it afterwards because I had no use for it. The second time was when I needed bootcamp for work and I used it for over a year until I needed more space. The 3rd time I reinstalled bootcamp I gave it more space than the Mac Partition and that led me to removing it again and buying a 2TB HDD instead. All the previous times I installed bootcamp there was no UFI boot or anything like that to my knowledge. I used bootcamp assistance and created a usb stick for installation. When I tried installing the newly released windows 10 via bootcamp assistance after I got the 2TB HDD I ran into some issues. It ended up working but I needed to boot from the windows 10 disc this time around and that's when I got the option to ufi boot and that was the only way it worked for me. Also an article online suggested I do that because I had no idea what UFI boot was. I don't remember how or when the Recovery HD was deleted because I didn't have it on my mac for a long time. I might have deleted it accidentally or it could have been something else I really don't remember.
