Trying to install Sierra on Toshiba Satellite P55t-C5114

I am new to hackintosh so please excuse me if I do not understand everything.

I was trying to follow this guide here: https://www.youtube.com/watch?v=VSYkUkngdb4

I cant find any information on this specific laptop when it comes to creating a hackintosh. I tried to install it through UniBeast, but the boot USB is not detected. This is a brand new hard drive, a 512GB SSD. The guide says to set the SATA mode in the BIOS to AHCI, but no such option exists. How would i go about solving this, if possible? I'm trying to make it so I can dual boot Windows 10 and Sierra, but I would just be happy if I could use sierra. Any help would be appreciated.
