I would suggest to write the _same_ ISO file to a USB stick of sufficient size, and leave the USB stick connected while running the installer. The installer should detect the USB stick and use that as the source for installation, regardless of how you booted into the installer. As long as both media contain the same data, this should be completely unproblematic. Think of it as a variation of, in the old days, booting the installer from a floppy (on a system that couldn't boot from CD) but actually installing from a CD. -- Michael Kjörling 🔗 https://michael.kjorling.se “Remember when, on the Internet, nobody cared that you were a dog?”
