raspbian – Raspberry Pi OS for PC not booting up

I downloaded Raspberry Pi OS for desktop (2021-01-11-raspios-buster-i386.iso, Debian Buster with Raspberry Pi Desktop from here, Kernel version: 4.19, Release date: January 11th 2021). My computer is an HP 15-db1000AU notebook with 64 bit AMD Ryzen 3 2.6 GHz with Radeon Vega Graphics, 4GB RAM. I made a bootable USB using Rufus 3.15, using all default settings provided when the iso was loaded. I tried booting from the USB, both with persistence and without persistence. In both cases there is some text in the beginning, then the computer boots up to the raspberry pi logo, then goes into a blank screen with a blinking cursor and nothing else happens. If I forcefully turn off the laptop by pressing the power button, there is text saying something like could not mount/unmount removable media and the computer suddenly turns off.

How should I troubleshoot this? Is this a live OS? Is there any way to try out this OS without actually installing it on a hard drive?
