New Build Won't Boot OS from Thumb Drive

Hey Everyone,

I am in the process of installing an OS of mine from my 8GB Thumb Drive. However, I am currently receiving the " Boot from CD/DVD: Disk Boot Failure Insert System Disk" screen. I made sure to change the First Boot order to - USB-HDD which is my Thumb Drive.

Why would it still expect me to be booting from my CD/DVD drive?

My motherboard is a GIGABYTE GA-Z68AP-D3

Thanks so much.

  1. Also to add, after changing my boot priority, i selected my USB Flash Drive as the main source. However, it still is asking me for the CD/DVD drive :(
  2. Are you positive the memkey is bootable? I would try it in a different machine if possible. If the memkey isn't bootable its jumping to the next thing in the boot order which is probably the cd drive or HD.
  3. So I was able to get a hold of a Windows machine to actually make my flash drive bootable. However, now that I put my bootable flash drive in my new computer to install the OS, I get this screen:

    "Loading Operating System....

    A disk read error occurred....

    Press Ctrl+ALT+Delete to restart"

    Anyone have any idea where this came from?
