Regular Ubuntu was installed instead of UbuntuDDE 22.04

> Downloaded iso file from the official downloads page (fosshost mirror)
> Created a bootable usb using UNetBooting
> Booted from the usb drive
> Saw this screen

> Chose the first option
> Regular Live Ubuntu was loaded
> Thinking that’s some kind of a weird bug, I tried installing it
> After the installation was completed, I was left with a pristine Ubuntu 22.04

This is really weird. I’m a noob regarding linux distros, so there is a high chance that I did something wrong. Excuse me, if that’s the case.
