Installed Brasero and created the .iso image…
The "Startup Disk " app “Make Startup Disk” dialog will not open up the input file to be filled in after I click “other” and highlight the .iso file, even after I right click on it and choose “copy location”. The only buttons there are cancel and open and they are no help.
Personally I have only 1 UEFI system on Debian 11.3 on a full non-proprietary hardware no-Wi-Fi system. Everything else is laptops where i disabled UEFI and ran legacy systems. Many of which require non-free firmware to work with the Intel Wi-Fi cards. UEFI has its benefits and like Wayland(Xorg replacement) I feel have not reached a mature enough state for average or novice user deployment.
My personal opinion is to access the bios and disable UEFI boot
