Everything working now on HP 2570p except the little joystick which I don't care about—More complete than my other hackintosh.
BUT... I can't access the bios setup: HP 2570p. It goes straight to clover. Esc, F9, F10, nothing works at start-up—even after exiting clover. The catch 22 is I probably need to get to the bios to fix this. I think the bios was set to boot hybrid. I followed the bios setup instructions, checking off everything I could that was suggested.
Different Approach: When I removed the windows 8 legacy HDD that was in the HP originally, I couldn't get to the boot options screen to choose the install USB stick. To get around that, I did the following:
From My other Hackintosh:
Carbon Copied my other Hack to a new SSD for the HP.
Reformatted new SSD, which left an empty EFI partition.
Installed OS x from the usb installer (from this guide) onto the new SSD.
Moved the EFI and config from this guide into the new EFI partition
Copied PBI to the new SSD
On the HP 2570p:
Put in the new SSD and booted to a working desktop
Ran PBI Rebooted and Voila!
Used Kext Wizard to rebiuld cache and repair permissions.
Everything is great but can't access the bios.
SOLVED: I win the idiot award. Switched drives to Windows 8, opened bios settings, Boot options/turn off Fast Boot.
