only boots to a live session

Newbie user just started investigating the use of LCNC for a mill build.

I downloaded LinuxCNC_2.9.2-amd64.hybrid.iso and used Rufus to make a stick.It boots to a live session and doesn't give an option to install to the SSD.
it does offer the choice of boot or options but I haven't found out what the options actually are or the syntax.
Its been years since my last foray into the linux world so am pretty much starting over.
Hopefully somebody will point me in the right direction.
I'm putting it on a ODROID-H3+ with 16GB and a 500 GB SSD.
 

it seems to have fixed itself.
Rebooted a few times and it started to show 6 options at startup so its now done.
Please ignore

Welcome and thank you for reporting back.
