Hard Drives Aren't showing when I try to install Sierra

I have created a Boot USB for Mac OS Sierra using Unibeast, however, when I load up the installer from the USB, it doesn't detect either of my installed drives. (I have an SSD and a HDD installed) Here is the hardware list for the laptop: Hp touchsmart 15 model 15-j051sa Intel i7 4700MQ 2.4ghz turbo 3.4ghz 8gb ddr3 ram 128gb ssd for os 500gb hard drive Nvidia GeForce GT 740M 2GB, with dedicated DDR3 2GB memory. Intel HD 4600 Video with upto 2GB shared RAM. Gigabit Ethernet. 802.11 B/g/n WiFi

Any help would be greatly appreciated? Thanks, Liam
