I installed ubuntu 20.04 in a new Acer Aspire laptop. After installation, I restarted the computer which boots straight to windows. I have seen several solutions that require restarting the computer, going into BIOS, setting a supervisor password and then selecting an EFI file as trusted (example of solution), but during that step I'm supposed to select "ubuntu" which is not listed. I'm stumped. What can I do?
Thanks
