Mountain Lion disk utility won't recognize HD

[jeff1986]

Hi guys,

I went to install Mountain Lion 10.8 today with a USB drive. I dropped the OS on with Uni beast to prompt the install. Everything begins great until it asks me where to install.....The area is blank and showing no HD..... I am running an HP DC7800 with a 1tb Seagate HD.
My Bios has IDE and RAID setting only. While on the RAID it allows me to go through with the install process up until that point of locating the HD. Any advice on this would be awesome!

Thanks!

Having the same issue, have no idea what's going on.

Your bios has to have an AHCI setting for hard drive storage.
