A bootable USB flash drive will help you get your Mac back to working condition, by letting you use all of the tools a fully-working Mac has available. In addition to being able to use Disk Utility, the Finder, and Terminal, and have access to the Internet, you can also load some specific emergency tools onto your USB flash drive.
. Booting from a USB stick is nowadays more and more important. More and more PCs (and servers) are delivered by default without a CD/DVD drive. To install the OS of your choice, USB sticks provide you the easiest possibility. In fact, it can even work out cheaper than burning a CD or DVD that you just throw away once the version is outdated. 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. Convert the ISO to UDRW format Mac OS X provides all the tools needed to convert the ISO image to UDRW.
The following command will convert the ISO image to the UDRW format. Hdiutil convert -format UDRW -o destinationfile.img sourcefile.iso You will notice that the destinationfile.img from the command will create the file destinationfile.img.dmg really. This is because the hdiutil program automatically adds the dmg file extension. This is not a problem as the file extension won’t affect the format of the image. Prepare the USB stick Check your USB stick and make a backup if there is any important data on it, as the next steps are going to delete everything on it. To prepare the USb stick we are going to delete all the partitions on the stick and create an empty partition. To do this we need to know the device name of the USB stick.
Open a terminal and execute the following command: $ diskutil list You will see a list of disks and partitions. The goal is to identify the USB stick in this output. Depending on your system configuration your output might look different from this one.
This appears to show 3 physical discs but it does not. The /dev/disk1 is a virtual disk created because of the partition encryption I enabled in Mac OS X. /dev/disk0 #: TYPE NAME SIZE IDENTIFIER 0: GUIDpartitionscheme.500.1 GB disk0 1: EFI 209.7 MB disk0s1 2: AppleCoreStorage 399.5 GB disk0s2 3: AppleBoot Recovery HD 650.0 MB disk0s3 5: AppleBoot Boot OS X 134.2 MB disk0s5 /dev/disk1 #: TYPE NAME SIZE IDENTIFIER 0: AppleHFS MacOSX.399.2 GB disk1 /dev/disk2 #: TYPE NAME SIZE IDENTIFIER 0: GUIDpartitionscheme.2.0 GB disk2 1: Microsoft Basic Data UNTITLED 1 2.0 GB disk2s1 As shown in the output above, the connected USB stick is a small 2.0 GB drive with a FAT partition on it.

We are now going to remove this partition in the next step. For the following steps we will need the name of the disk which in this case is “/dev/disk2”.
With the following command the data on the disk (your USB stick) will be deleted! $ diskutil partitionDisk /dev/disk2 1 'Free Space' 'unused' '100%' With this command the USB stick was re-partitioned to have 1 partition without formatting and 100% of the size of the stick.
If you check it again with “diskutil list” you will see the changes already, also the USB stick will no longer be shown in the Finder. Copy the image to the USB stick Now we can copy the disk image we created to the USB stick. This is done via the command. This command will copy the image to the disk (substitute the appropriate disk name for your USB stick here, as with the re-partitioning command): $ dd if=destinationfile.img.dmg of=/dev/disk2 bs=1m The dd command does not show any output before it has finished the copy process, so be patient and wait for it to complete. $ diskutil eject /dev/disk2 To eject the USB stick, use the above command. After this is done, the bootable USB stick is ready to be used.
Read more of my posts on my blog at. Thanks to John for pointing out some slightly different behaviour in Mac OS X 10.9 (Mavericks). While Mac OS X 10.7 (Lion) allows you to execute the “dd” command with your user priviledges, Mavericks does not. So if you are using Mavericks and get the “Permission” error, the solution is to use sudo.
Sudo allows you to run the “dd” command with root priviledges. While the root user is disabled in Mac OS X by default, sudo is allowed for users which have the “Allow user to administer this computer” option set. When using sudo as shown below, you will be asked for your password to proceed. $ sudo dd if=destinationfile.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!
Also, you’ll get some information about “TransMac” software. What is “TransMac Software”? From where to download?
How does it work? You need the following materials to create bootable USB Installer for Mac OSX on Windows 10 operating system. What is TransMac Software? TransMac from Acute Systems is Windows software that can copy and manage files and folders on Apple drives and devices, including Mac-formatted hard drives, flash drives, and other storage devices, as well as open and burn disc images and.dmg and.sparseimage files. It’s shareware that you can try for free for 15 days. Recent updates include an improved open file dialog, speed enhancements, and Windows 8 compatibility. TransMac for Windows can open Macintosh format disk drives, flash drives, CD/DVD/Blu-ray media, dmg, dmgpart, sparsebundle and sparseimage files.
Features: create, compress and expand Mac dmg disk images, built-in CD/DVD burner to burn ISO and dmg files. The new version is also compatible with Windows 10. Create Bootable USB Installer for Mac OSX Using TransMac To create bootable USB installer for Mac in order to Install Mac OS X El Capitan on Windows, on Mac or on VirtualBox, you have to create bootable USB flash drive.
Let’s get started that how to do it. First, you have to download TransMac software for Windows and install it on your computer.
The Installation process is very easy and everyone can do it without any problem. Once you’ve installed then you will see the screenshot below. Right-click on the flash that you want to create bootable for Mac with TransMac software then choose “ Restore with disk image“. Hi there, just yesterday I bought a used MacBook Pro 2007 and it came with Mac OS X Lion. Unfortunately I erase the disk with the system and now when I try to download a new copy of lion through Mac OS X Utilities I always get “Item temporarily unavailable” (I tried different apple accounts, one of then with lion in history purchase, I tried to correct the date on terminal and even did an reset nvram).
My next step was Internet Recovery Mod, but once again no results, option+command+r didn’t work. Already getting crazy I was hopping to make an bootable usb disk and install from there. I started by preparing my usb 3.0 disk with diskapart command in windows terminal and fallow all the steps in TransMac with different mac os versions but the final result was always the same, when I plug the usb pen in my mac, I turn on pressing option key and I select usb but it always go to Mac OS X Utilities. Any ideas what to do now? Please someone help! Hi there, just yesterday I bought a used MacBook Pro 2007 and it came with Mac OS X Lion.

If again you are unable to Boot into USB installer then Create a Bootable Installer again with a different USB drive. Or you can also also.
1: Load Optimized Defaults 2: Set The SATA Controller Mode to AHCI 3: Set the Boot Priority to UEFI 4: Set OS Type to Other OS 5: If your CPU supports VT-d, disable it 6: If your system has CFG-Lock, disable it 7: If your system has Secure Boot Mode, disable it 8: If you have a six series or x58 system with AWARD BIOS, disable USB 3.0 9: Save and exit. 10: If your system didn’t boot automatically then go to Boot Manger and select the Bootable USB Installer that you create in step 1, Manually.
