For most Linux distributions the ISO for burning a CD/DVD is available freely on the internet. In this post I’ll assume you have already downloaded the bootable ISO image for the OS of your choice, but how to get the ISO image onto the USB stick? Advertisements The ISO file you have downloaded contains an image of the entire media. It includes all the files necessary to boot your PC/server. This image format is sadly not directly usable to copy onto the USB stick. We first need to convert the image from an ISO to a UDRW (Read/Write Universal Disk Image Format) which we can copy to the USB stick. Some of the steps to create a bootable USB stick could be done in the GUI as well, but as some of them can’t and you have to go to the shell anyway, I decided to do all of the steps in the shell.

The blocksize cannot be any different from this because of the nature of the MS-DOS FAT partition structure.

Final Solution Well, I was dealing with this problem, but after a little digging I found a be-all end-all solution for creating Windows/Linux bootable Flash Drives on the mac. Disk Utility, for whatever reason, is prohibited from writing Joliet (ISO 9660) onto MS-DOS FAT 32 Flash Drives, though it should definitely work. The best way to accomplish your goal is the following: Open Terminal Type 'diskutil list'. You'll see your primary hard drive (probably listed under /dev/disk0) and your Flash Drive, which will be listed as /dev/disk#, with # being any number that isn't zero. REMEMBER THE DISK LOCATION In the next line, type 'diskutil unmountDisk /dev/disk#'. You'll see this message on success: Unmount of all volumes on disk# was successful Now type, 'dd if=( DRAG ISO/DMG HERE) of=/dev/disk# bs=1m' Do not forget bs=1m!

When using sudo as shown below, you will be asked for your password to proceed. $ sudo dd if=destination_file.img.dmg of=/dev/disk2 bs=1m Please keep in mind that after you have entered the password, the dd command does not show any output. So please be patient until the dd command has finished. Thanks again to John for pointing this out!
