UEFI Option not available during installation

I was trying to install Qubes as a first try but during installation there was no place to select the partitions.
I then tried installing on a USB - but then again there was no option to select UEFI or which partition to use as a boot partition and which one as a root partition - am I doing it wrong ?
Is this a feature Qubes is working on ?

How do you create installation medium?

There’s no UEFI option in installation, it’s how you boot the media, either legacy bios / UEFI

I first downloaded the OS and burned it into a USB using balena etcher - then booting from this usb i installed it on another USB.
My hard drive is partitioned and I am running PoP - I didnt see an option to install it on hard disk partition.
