Problema al intentar instalar Fedora

I am trying to install fedora from a USB memory and when I start the installer I get 2 errors: failure reading sector 8x26860 from hde and the other error you need to load the kernel first, my pc has an AMD Phenom II X4 840 processor, 4 of DDR2 Ram, 120Gb SSD and the mcp6pb m2+ motherboard.
PS: This is the first time I put Linux on this PC.
