I have tried to set up a dual boot on a Win7 machine with no luck.

I have made two USB boot drives and both boot fine.

When I attempt to install they both fail saying can't find installation media.

Confused because how could it boot from the same media it says it cannot find?

1. USB Live boot
2. USB Install boot

Am I supposed to have a third USB Thumb Drive with the ISO on it? Nothing in instructions seems to explain how to provide the install media if not the drive used to boot installation.

Same problem both cases.

( Have already cleared about 125GB empty disk space on drive so don't need the GParted step. )

All help welcome!
