[SOLVED] Still Waiting for Root Device with 10.8 on HP Probook 4530s

[instant idiot]

Hello

 

10.8 installed (using myHack) and runs beautifully from a USB drive; however, upon attempting to boot from the internal SATA HDD (in AHCI mode of course) it just hangs at "Still waiting for root device." The odd thing is, my internal SATA drive is detected just fine from 10.8 when booted from the USB stick.

 

Thanks for any ideas!
