How to reload HA on HA green

Hi I have bought a HA Green and it has issues. I have tried every suggestion on here and the internet and nothing has worked. I would like to completely wipe it and load HA as a new install. Can anyone tell me how and what version to install. I’ve seen many videos on installing on a raspberry pi but I don’t know what the HA green is considered to be ie pi, nuc etc. Thanks in advance for any help.

NOTE: A lot of people seem to miss this step:

Thanks i tried that left it for about 12 hours and still had the same issues

What issue are you having?

it currently is waiting for supervisor to start

I have set HA on my laptop to get started until i can resolve this issue.
By doing this i cant seam to access the GREEN, i currently have it connected to a monitor. Under some advice i did something that has taken it back to this state.
