There is a way to get things done...but first, need to know a few things.

What is the make and model of the computer that is broken.
Can you enter BIOS (set-up) to see if booting to an external device (usb) is supported.
Is their a hidden repair partition on the computer to restore the computer back or does it actually require that it be created from CD.

Do you have access to a USB external CD drive or storage drive that can be used to restore the computer
