What (Intel I assume) chipset do you have? HM77 "Panther Point"? Ivy Bridge i5 3210M processor I assume? Pretty much all of HP's laptops for the pat two quarters have been either AMD A8/A10/A12 based or Intel Ivy Bridge i5/i7 based, so I assume you have an i5, if it's an i5 it's almost certainly a 3210M.
We also have the same BIOS, particularly that USB 3.0 thing, and my Hackintosh setup has no effect from that setting, Auto or otherwise, it still boots into OSX with no issues.
Did you install the modified-for-RAID AppleACPIPort.kext from the guide I linked before to your USB installer? You must use KextWizard to do this.
How are you accessing OSX to make the USB installer, VM or a legit Mac?
What USB drive are you using? Include brand (Lexar, SanDisk, HP, etc.), size and whether it's USB 3.0.

Yeah nevermind on the specs, you have a less-powerful Ivy Bridge i5 but the same Panther Point HM77 chipset.
