I want to install Ubuntu beside Windows 8 following this post on Ask Ubuntu guide, but I don't know if my Windows installation is booting in UEFI mode or in legacy mode (and it's said to be important in the post under the "DUAL BOOT ISSUES" paragraph). How do I get to know it?

If you would prefer to check from Ubuntu:

In Ubuntu open the terminal and type "sudo parted -l".

Scroll to the part with information on the disk your Windows installation is using. Under "Partition Table:" it should say gpt or msdos. GPT is required for Windows to run in UEFI mode. msdos means you're using BIOS/Legacy Mode.
