Help needed please!

Hi guys,

I’m trying to i stall Sonoma on my late 2014 Mac mini. I have downloaded the operating system to my mac and the installer on my flash drive but I can’t get the reboot screen when pressing option. I have started in recovery and occasionally manage to restart from there and get the boot screen but no oclp or flash drive option come up. Have I done something wrong?
