Make Ubuntu startup USB drive under Mac

1. Use Hdiutil to transfer ISO to DMG
#路径

Hdiutil Convert-format udrw-o ubuntukylin-15.04-desktop-amd64.img ubuntukylin-15.04-desktop-amd64.iso

This time we got a. DMG hard drive image file.

Now we insert the USB drive with Df-h to view the USB flash drive.

2. Unmount USB Stick photographed image

Diskutil Unmountdisk/dev/disk2

This place directly with disk tool, uninstall also can, but note is uninstall do not exit or pop-up and so on. Do not do this, the back of the DD in the time will appear without permission, the disk is being used a class of hints.

And now I'll cuff photographed like.

sudo dd if=ubuntukylin-15.04-desktop-amd64.img.dmg of=/dev/disk2 bs=1m

This process is a bit slow, and there is no progress hint, you need to wait patiently. After the end, you will be prompted automatically, select "Eject".

This disk is not recognized because the format of the USB flash drive is incompatible with the Mac. Don't worry, pull out. Just the next time if you redo the startup disk, you need to format it again.

Now you can set the BIOS to the machine to boot, insert a USB flash drive, follow the CD to start the same operation is OK.
