Windows 8 / 8.1 Boot from DVD
As more Windows 8 / 8.1 computers come in for "help", I've had to deal with the normal issues.
In one case today, I found a Windows 8 laptop that would not boot from DVD (an ASUS K55A)
I might normally test memory and the hard drive that way.
I might normally boot to a Linux variant that way to see how the hardware is acting.
etc.
I might normally boot to a Windows DVD in order to run a repair of the appropriate type.
In this one case I found that there were UEFI (i.e. bios) settings needing change.
In this one case I found that the settings were obscure and couldn't be dealt with in "real time" on site.
Is this common?
Does it carry over into Windows 8.1 necessarily? Or is it OS independent really (it seems so)?
Does one need to change .iso-based DVDs to UEFI flavor?
Ditto USB sticks for booting?

Thanks! I didn't recognize "CSM" in the system I was dealing with. And, it required an extra reboot to get the UEFI settings needed: one boot to get the CSM set and another boot to allow booting from the DVD, etc.
