Fails to Boot After Using MultiBeast

[dapanda]

I initially had a i5-4670k build running with integrated graphics on Yosemite. Booting with Clover.

Audio was not working, so I downloaded MultiBeast and attempted to install the Realtec 892 to get audio to work.

Unfortunely, it seems that quite a few other things were installed at the same time, ruining my boot.

Is there any way I can go and simply delete these things? I cannot boot from USB, the "Recovery" option of Clover does not work either. -v doesn't yield much, since it almost immediately crashes.

Ideas?

I think I may have somehow selected legacy boot.

I'm noticing that I saw a screen like this to start up, compared to this one.

I saw files like AHCI_3rdParty_SATA.kext, AppleHDA.kext, and NullCPUPowerManagement.kext were recently added/modified from my system/library/extentions folde.

Booting from USB/recovery just loads a gray screen on one monitor, and a slanted and messed up apple logo on the other.

I have fixed the issue by creating another El Capitan USB that was able to keep everything on my computer.
