Set up USB drive with single ISO
The ubuntu walk through work for most linux derivative.
The process uses Etcher which does not support writing to a partition of a given drive
Set up USB drive with multiple ISO's
- partition the drive
- unmount the partition we wish to write to
The most direct solution to this is to use the terminal.
Assumes disk is partitioned, formatted and ISO's are downloaded.
- identity target disk identifier:
- unmount target:
diskutil unmount disk3s8
- flash or burn iso to partition
sudo dd if=<path-to-iso>/ubuntu-21.04-desktop-amd64.iso of=/dev/rdisk3s9 bs=4m
There is no progress bar so just wait it out, how long the ISO copy process takes depends on a variety of things, including the speed of the Mac, the speed of the target volume, and the size of the ISO file being copied or burned to the destination.
A usb drive can be partition from diskutility
navigate to view and "show all devices"
sudo umount /dev/<identifier>
diskutil unmount /dev/<identifier>
diskutil unmount /dev/disk3s9
diskutil unmountDisk /dev/disk3
Flash OS images to SD cards & USB drives, safely and easily.
