You need the Helipack: there are three ways of getting this gold bolt. Right at the beginning, look a bit to your right. There should be four yellow robots, and you will see two steps(tiers). Go in front of the steps and look up. You will see the gold bolt on a ledge a bit to the right. With the Helipack, get on the first step, (Some people may have an easier time starting from the second step.) face the wall with the ledge, boost-jump (R1+Cross) and while in the air, press (Up+R1+Cross) and you will grab the ledge. Then, pull yourself up to get the gold bolt.
