I'm running windows 7 enterprise at mcdonalds.

We we're given a recovery disk to restart our machine with.

Our optic drive then stopped working.

I've tried burning an iso image of the file on to a USB stick and booting from that. However I get as far as a screen that says boot: and will not recognize the iso file.

I then tried copying the entire contents of the disk onto a the USB which included a file called BOOTMGR and autorun.

When I type BOOTMGR it says:

Loading BOOTMGR... Ok
Booting kernal failed: Invalid arguement'

You need to create a bootable USB stick, currently your PC doesn't know it can boot from the USB stick as there is no boot sector.

There are many free programs for doing this, Rufus is one (http://rufus.akeo.ie/), you can also use DISKPART in windows cmd (http://www.wikihow.com/Make-a-USB-Bootable)
