I tested many more ISO to USB tools for the sake of competition—and to bring you the best overall picture 'Error: ISO image extraction failure' We change many of PCs in which some are running on How to Create a Bootable Multiboot USB for Windows and Linux. How to Fix the Master Boot. Part 2: How to Make Bootable USB Flash Drive from ISO (Mac) Etcher is a great tool to create a bootable drive on computers running Mac OS. There are some initial preparatory steps that you will need to execute before actually creating the boot drive from your ISO file.
The instructions below are specific to the Disk Utility program available on the Mac OSX Operating System on the Macintosh computers in IT Computer Classrooms. Even if your computer has a different version of Mac OS X, these instructions should provide a general guide for completing this process. Refer to the documentation provided with your Mac operating system software if you need more specific information. Burn a DMG or ISO File to Disk After you have downloaded a program's installation file (.dmg format for a Mac-compatible program,.iso format for a Windows-compatible program) to a Macintosh computer's hard drive, you can burn this.dmg or.iso file to a blank CD or DVD. You can use this disk to install the program on another computer, or have a backup installation disk in case you need to reinstall the program in the future. You can use a Mac to burn an.iso file to a disk, and the resulting installation disk will run properly on a Windows computer.
Dmg or.iso files that are larger than 4.7 GB, you will need to use dual layer DVD. See for more information about different types of recordable DVDs. To burn a DMG or ISO File to disk:. Start Applications Utilities Disk Utility.
The Disk Utility window will open. The Mac's available drives (e.g., hard drive partitions, CD/DVD drive) will be listed by name in the left pane. Insert a blank CD or DVD disc into the Mac CD/DVD drive. Note: If the CD is blank, the You inserted a blank CD pop-up window will appear.

Select Action Open Disk Utility, then click OK. The Disk Utility (a.k.a. SuperDrive) window will reappear. Drag the.dmg or.iso file from a Finder window or the desktop to the Disk Utility window, and drop it in the left pane in the empty area below the Mac drive names. The.dmg or.iso file name will display in the left pane of the Disk Utility.
Note: You can drag and drop multiple files to the Disk Utility. Select the.dmg or.iso name in the left pane of the Disk Utility, then click Burn (top left). The Burn Disc In: window will open and display the destination (your blank CD/DVD) for your file.
In the Burn Disc In: window, click Burn. The Disk Utility Progress window will open and the burning process will begin. When the burning is complete, the disk is ejected from the drive and the Disk Utility Progress window displays a message that the image burned successfully. The Disk Utility Progress window will close. You can now close the Disk Utility and use your installation disk. About Recordable Media Types There are two types of recordable CDs and DVDs: CDs and DVDs labeled 'R' can only be recorded on once, while those labeled 'RW' allow you to write data to them once and then add more files later. You can also erase the data on CD-RW or DVD-RW disks entirely and re-use them, which you can't do with DVD/CD-Rs.
You can use either kind in IT Computer Classrooms.
Purpose Just to make sure we’re all on the same page here, the purpose of this exercise is to take an that you’ve downloaded that contains a bootable filesystem intended to be burned onto a CDROM and instead put it on a USB key so that a machine with the ability to boot from USB keys can boot it the exact same as if it were a CDROM. NOTE: Intel Based Apple Machines contain an EFI BIOS that CANNOT boot USB keys. You will not be able to put your OS X.iso file onto a USB key and install it onto an Apple machine.
We’ll be doing most of this from a terminal, with the help of disk utility for some things. Prepare the USB key We’re going to wipe the partition structure on the USB key. THIS WILL DESTROY ALL DATA ON THE KEY! Open up Disk Utility (it’s in /Applications/Utilities/). Now do the following:. Select the USB key (select the root device, not its partitions).
Select the partition section at the top. Change the Scheme to 1 Partition.
Change the Format to Free Space. Click Apply You will get a confirmation dialog appear ensuring you really want to delete all data on the key, choose Partition. Once it’s completed you can quit out of Disk Utility. Update: The purpose of doing this is mainly to ensure that the USB key is in a consistent known state and also to ensure that any volumes are not mounted by OS X. It is not required and you can skip it if you’d rather just unmount the volumes yourself. Preparing the ISO image Now that our USB key is ready, we need to get our.iso image into a format that we can copy to it. Open up a Terminal (it too is in /Application/Utilities, and I’ll assume you know how to use the terminal) Now, convert the image from a ISO to a (or UDRW).
Here I’m using the Debian 6.0.7 Net Installation ISO, but you can use anything else that’s an ISO file. #542: hdiutil convert -format UDRW -o debian-6.0.7-amd64-netinst.img debian-6.0.7-amd64-netinst.iso Reading Master Boot Record (MBR: 0) Reading Debian 6.0.7 amd64 1 (AppleISO: 1) Reading (WindowsNTFSHidden: 2). Elapsed Time: 2.054s Speed: 81.8Mbytes/sec Savings: 0.0% created: /Users/evan/Downloads/debian-6.0.7-amd64-netinst.img.dmg Once completed this will create the.img file.
The hdiutil function likes to append a.dmg suffix to the file so it will probably end up.img.dmg after conversion. Copy the image to the USB key We’re finally here. The easy part, actually copying the image to the USB key. First run diskutil list to get a listing of the disks in your machine so you can identify the USB key. It will look like this: #543: diskutil list /dev/disk0 #: TYPE NAME SIZE IDENTIFIER 0: GUIDpartitionscheme.250.1 GB disk0 1: EFI 209.7 MB disk0s1 2: AppleHFS Macintosh HD 249.7 GB disk0s2 /dev/disk1 #: TYPE NAME SIZE IDENTIFIER 0:.1.0 GB disk1 Here mine’s /dev/disk1. Update: We want to use the RAW disk device so that our copy will happen much faster because the RAW disk device provides unbuffered access to the device (See this `Apple mailing list post ` for more info).
This is accomplished by simply prepending ‘r’ to the device so that /dev/disk1 is going to become /dev/rdisk1 Update 2: Specifying a blocksize of 1m will also significantly speed things up. Next we use the dd command to copy the image over.
#544: dd if=./xbmc-9.11-live-repack.img.dmg of=/dev/rdisk1 bs=1m On the command line we specify the Input File using if= and the Output File using of= and dd will copy the data from input to output, block by block. Once it’s completed you can exit Terminal and remove the USB key from your OS X machine, it should now be able to bootup your ISO on another machine.
