Will you please elaborate on what you did to fix it?
Thanks for all the great support. I love this hackintosh community. I'll try to help out a bit here.
I'll elaborate on how I fixed it. Follow my instructions at your own risk, but it worked for me, at least. This should be painfully simple/easy to follow:
1) Go here:
http://www.tonymacx86.com/hp-proboo...-install-yosemite-hp-laptops-clover-uefi.html
2) Look under "Install OS X Yosemite," and make a Clover USB bootable drive. When making the USB drive, ignore the second partition. You only need the "clover" partition, as mentioned earlier in this thread.
3) DON'T FORGET to download the required files. ("Clover.zip" and "Config.zip")
4) Copy required files from the zip files to your new clover bootable drive.
5) Follow instructions on how to get your ProBook to boot off the drive (F9...EFI...all that stuff)
6) Your computer should boot by this time. When it does, open Clover Configurator
7) Click "Mount EFI partition" (or click on "Mount EFI" followed by "Mount EFI partition")
8) Put in your password
9) Click the little button for "Import Configuration"
10) Navigate to your EFI partition, then the EFI folder, then find the clover folder, and select the "config.plist" file
11) Select "Kernel and Kext Patches." Find anything labelled "second stage patch," highlight them, and click the minus/subtract button just off the bottom of the list.
12) Save, reboot, pray
