To install Ubuntu 22.04 on an unused PC, I created a bootable USB.
Preparation
- Mac mini (Apple M1)
- USB memory 32GB (more than 8GB)
Prepare an USB memory
Download the OS image
Download Ubuntu Desktop 22.04.02 LTS (4.6GB).
Format an USB memory
Erase the USB memory with Disk Utility software in Mac. Format type is "MS-DOS (FAT)".
* You must select the USB memory you'd like to erase. If you select your PC, all data will be deleted.
Write the OS to the USB memory
Write the OS to the USB memory with Etcher.
Choose the OS file as "Flash from file" and the USB memory as "Select target", and execute. It takes about 5 minutes to write.
