I'd like to do a full disk encryption. I realize I cannot do this since I've already installed ubuntu, so I'm fine with doing a fresh reinstall.

The problem is when I get to the step of selecting "wipe entire disk and install ubuntu", then click on Advanced settings, the option for full disk encryption is greyed out. It is the only option that is greyed out, I am able to select the other three.

What gives here? I'm wiping the disk and installing from a usb so why wouldn't it allow me to encrypt? The only thing I can think of is I might have some strange setting wrong in the BIOS, but I'm not a computer guy.
