I am trying to reinstall Ubuntu 20.04lts on an iMac running Ubuntu 20.04lts as the only os. I cannot figure out how to access boot priority menu to allow the system to boot from USB drive. Any ideas?

  1. before starting your iMac plug in the USB key
  2. after starting the iMac press and hold the alt key immediately until boot menu with drives appears
  3. select the USB key and you're ready to go.
