This question already has an answer here:

I downloaded the 12.04.2 Desktop amd64 ISO from the main website. Then I burned it onto a DVD, but when I restart, the computer won't recognize the DVD when it boots.

Have I downloaded the wrong one as there is Wubi on the DVD?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Which Ubuntu were trying to download? How are you trying to install? –  Mitch May 13 '13 at 6:19
"Files Ready to Be Written To the Disc"? Looks like something got wrong while burning. It can also be due to 'Secure Boot' blocking you. –  Jop V. May 13 '13 at 17:31

That's the right ISO. There is a wubi.exe on it (just ignore it - it has other uses other than just installing inside Windows).

There are two potential issues:

  1. A bad ISO that was corrupted on download
  2. A bad burn

To check the ISO, refer to this: help.ubuntu.com/community/HowToMD5SUM To prevent a bad burn, use the slowest possible speed and refer to this: www.ubuntu.com/download/desktop/burn-a-dvd-on-windows

Make sure you go into the PC Settings located on the bottom of the right side menu pop-up in Windows 8 and turn on the boot from DVD/USB.

The problem can be with the boot mode. A UEFI boot won't recognize a Legacy DVD, so if your Windows 8 is installed in the UEFI mode, and your DVD is Legacy, then you need to change the boot mode from your boot options, else get a UEFI supported version.
