Installing yosemite 10.10.5 on my toshiba satellite p55

[AlexLorton]

when trying to boot from the usb for the first time i get into the boot loader just fine but when i click on the yosemite option it goes black blinks the apple logo then back to the boot loader. i ran this in verbose mode to see where things were going wrong. it looked fine until it hit starting darwin x86_64 then it went black and back to the boot loader. any ideas on whats going wrong?

system: Toshiba Satellite p55
Processor: intel core i5 4200u/intel hd (4400) Graphics
