[操作系统]Generate Ubuntu Install Media On Mac


Opps, my computer system was broken again... Let's repire it.


Introduction

The system of my PC is broken. I could enter the UEFI setting. So that means I coud start my PC using USB flash drive. But first of all, I need a Installer driver.

ISO to DMG

I have a xxx.iso. I need to convert it to xxx.dmg file.

hdiutil convert -format UDRW -o xxx.img xxx.iso

The process is very fast.

Install to USB Flash Driver

Firstly, unmount the target driver.

# Obtain your disk name.diskutil list# assuming that your USB flash driver is named disk9diskutil unmountDisk /dev/disk9

Then, write data to this flash. Be careful not to mistake the flash name.

# The following command cost some minutes.sudo dd if=where your img.dmg file exists of=/dev/rdisk9 bs=1m# finally eject your flash. All done.diskutil eject /dev/disk9
