Hey everyone! First timer here. I'd like to thank the entire community before continuing. I lurked on here for a bit before building my first hackintosh, & all the documentation has been overwhelmingly helpful for a noobie. I know someone will ask my setup, so here it is:

Motherboard: GA-Z97M-DS3H *Accidentally bought the wrong model :|
Cpu: i5-4960k *not overclocked **yet ;)
Cpu-Cooler: Coolmaster Hyper 212 Evo
Ram: Corsair ballistix 16gb 1600mhz
SSD: Samsung 850 Pro 256gbCase: Thermaltake Core V21

So, I couldn't get the noobproof recommended unibeast/multibeast setup working past installation. Now after getting Clover working, I realize it was just a few flags preventing that. But anyways, I got it booted, configured it how I liked, then installed windows onto a second partition I made - no issues. Came back into OS X and started messing with options that I THOUGHT knew what they did. Guess what? I was wrong. The worst part is I don't remember what I changed. Lesson learned: backup & don't experiment.

My OS X partition is no longer bootable by itself. My bios sees the partition, but when I select it, it just tells me to insert a proper boot disk and try again. By popping in my install flash drive and using that boot loader, I am able to access the partition. For whatever reason, my Recovery partition is not behaving properly and neither is attempting to reinstall using the install flash drive. Both are throwing back black screens that I can't do anything with.
Here is my partition table, I'm guessing we'd need this to figure out a solution anyways:
Code:
/dev/disk0   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *256.1 GB   disk0
   1:                        EFI EFI                     209.7 MB   disk0s1
   2:                  Apple_HFS Macintosh HD            109.5 GB   disk0s2
   3:                 Apple_Boot Recovery HD             650.0 MB   disk0s3
   4:         Microsoft Reserved                         134.2 MB   disk0s4
   5:       Microsoft Basic Data                         104.7 GB   disk0s5
/dev/disk1
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *64.0 GB    disk1
   1:                        EFI EFI                     209.7 MB   disk1s1
   2:                  Apple_HFS Install OS X Yosemite   63.7 GB    disk1s2
/dev/disk2
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *24.1 MB    disk2
   1:                  Apple_HFS ut*****t-37979          24.1 MB    disk2s1
Ignore the ut*****t mount lol

Also, here's the Boot section of Clover Config.http://i.imgur.com/O2AHFxd.png

And finally, here's my EFI file heirarchy so you guys can see if anything looks unusual by means of missing files. I tried using rEFInd, but it didn't work. I deleted the folder from my partition, but residual files may be elsewhere. http://i.imgur.com/NZaTv8F.png

I'd like to fix this without reinstalling, but will if I absolutely must.

I ran a report to give slightly more detailed info. Idk, may help.

Formatted the EFI, used the last step of the Clover guide to reinstall it, then threw my microsoft boot in from a backup. Worked like a charm, but I had to reapply all my kexts and stuff.
