I downloaded the ISO for Debian's net installation to a computer running OS X. I want to put the data from the ISO onto a USB, so that I can install Debian on another laptop (not an Apple laptop). That laptop currently has no system installed, so I must prepare the USB drive on the OS X computer.

First, I tried installing UNetbootin on the OS X computer. When this bootable USB didn't boot, I found a bug report here suggesting that, although UNetbootin lists a version for OS X, it is actually not able to create bootable USBs.

Next, I tried the instructions at DebianEeePC How-to:

dd if=debian-7.*-netinst.iso of=/dev/disk1s1

This took about 10 minutes, reported no errors, but the USB still is unbootable.

  • In the past, USBs created with UNetbootin on Windows, and using the dd method in Linux worked successfully, but at this present time, only have OS X available to me.

How can I create a bootable Linux installation USB from an ISO in OS X?

You have to Convert the ISO to UDRW format using:

hdiutil convert -format UDRW -o destination_file.img source_file.iso

for Further steps and reference click this link,

go with the steps: Create bootable USB stick from ISO in Mac OS X

Is the resulting image bootable on non-Apple hardware? Documentation on hdiutil says UDRW is a UDIF read/write image format, and wikipedia claims that UDIF is Apple-specific proprietary format. –  cnst Apr 26 at 16:46
