I'm trying to set up a UEFI-boot of Windows 8.1. However, I seem to be unable to install it with a USB drive (previous question), and when I try to install with a DVD (the same iso), I don't get the UEFI boot option on startup, contrary to what happens when I use a DVD burned with e.g. an Arch Linux live install.
How exactly could I be able to boot with UEFI my Windows 8.1 iso from a DVD?

You need to setup boot-loader inside your bios settings.
If your computer has enabled Legacy Support, disable it if you want to have UEFI support.
You would need to setup UEFI boot order and setup the DVD as the main source in some cases.
Also try to disable Secure Boot in your bios settings to successfully install the system in UEFI boot mode.
We need more info about your motherboard or a laptop if you want us to help you with more details.

The .iso should already be EFI bootable disk since it has the required drivers – Ramhound – 2014-10-13T23:18:39.030
@Ramhound That's what I though, but the fact is that I can use UEFI to boot into the USB but not into the DVD, which is weird since both are using the same Windows 8.1 iso – joaocandre – 2014-10-13T23:22:27.010
1If that's the case the I suspect the method of burning the disk – Ramhound – 2014-10-13T23:31:24.143
You did set the computer to boot from CD/DVD first, right? Does your computer have secure-boot, is it on or off? – Robin Hood – 2014-10-13T23:49:11.017
I press F12 to reach the boot options at boot, the motherboard throws a list of the available options. If the DVD/CD allows EFI boot, the option appears. I have Secure Boot disabled. – joaocandre – 2014-10-14T13:58:26.397
