Why You Need a Bootable USB Drive

Installations from a USB flash drive have become one of the easiest ways to update your computer with a new operating system. A USB installation is quick, extremely portable, and has the bonus of reverting to a storage device following the install. See our introduction to using flash drives on Windows 10How to Use a Flash Drive on Windows 10How to Use a Flash Drive on Windows 10Got a new USB flash drive but not sure how to use it? Here's everything you need to know about how to use a flash drive.Read More if you need some background.

You’ll find a fair few ISO to USB tools out there, and they feature a range of tools for beginners and advanced users. Let’s take a look at the burn time, and the resources available to each software. For science!

Note: To keep this test fair, I’m going to burn a copy of Windows 10 Insider Preview Build 17713 x64 to an 8GB Integral USB flash drive, formatting the drive between each burn.

A Mini-Glossary of ISO-to-USB Tool Terminology

Before we plow into the testing phase, there are a handful of acronyms I’d like to spell out, and a few other bits of ISO to USB jargon we’ll clear up.

• Bootloader Options: The bootloader loads the operating systemHow to Solve Most Windows Boot ProblemsHow to Solve Most Windows Boot ProblemsIs your Windows computer not booting up? It could be because of a hardware, software, or firmware error. Here's how to diagnose and fix these problems.Read More.

Instead of assigning individual disk sectors, the file system assigns contiguous groups of sectors, called clusters.
• File System: Controls how data is accessed and stored. Without it, your data would lump together with no beginning or end. A file system defines easy access. There are different file systems available, though your burning tool should discern your requirements via the ISO you use.
• Bad Sector: Some ISO to USB tools allow you to perform a bad sector check. Before the burn commences, your USB will be scanned, fixing any irregularities to ensure your installation is smooth. Somewhat like defragmenting your desktop, but on a much smaller scale.

Now, in no particular order, here are the ISO to USB burning tools with their respective times.

Want the TL;DR? Check out the best ISO to USB comparison video below!

1. Rufus

Features: Partition schemes, file systems, automatic ISO detection, target system type, mode of bootable, bad sector checks, ISO write mode

First up, Rufus. Rufus is a very small executable that has consistently improved its offerings over the years. Along with standard ISO to USB options such as cluster size and file system, Rufus now automatically detects settings for the ISO you select and fills in the optimal settings. Furthermore, Rufus has a hidden Advanced Mode with a bunch of extra options.

Rufus clocked in at 21m12s which is definitely not the fastest. Regardless, Rufus is an excellent ISO to USB tool.

2. Windows USB/DVD Download Tool

Features: None

Such an eloquent name. You select your ISO. You select your media type; USB or DVD. You click Begin Copying, and off it goes. In what is the most basic of basic UIs, and with only two options, the Windows USB/DVD Download Tool is almost sublimely simple, comparable only to ISO to USB.

Windows USB/DVD Download Tool came home in 17m51s which puts it toward the top of the ISO to USB timings board.

3. RMPrepUSB

Features: Bootloader options, file systems and overrides, grub4dos, syslinux, QEMU

RMPrepUSB is one of the most complete ISO to USB packages on this list. Aside from the features above, it comes packed with a host of other bootloaders, DiskDoctor, Speed Tests, and individual user configurations for frequently prepared drives.

RMPrepUSB clocks in with a 21m38 putting it firmly toward the top of the timings board but, like Rufus, the features more than make up for the slightly slower time.

4. YUMI

Features: Multiboot, ISO auto-download

YUMI (Your Universal Multiboot Installer) is another multiboot ISO to USB installer with settings for a vast range of Linux, Windows, and system utilityBoot Multiple Live CDs From One USB Disk With YUMI [Windows]Boot Multiple Live CDs From One USB Disk With YUMI [Windows]Put multiple bootable tools onto one USB drive, then pick which one you want to boot when your computer starts up.

You scroll down the distribution list and check for the ISO you want, then select the corresponding ISO on your system from the box below. Don’t have the ISO? YUMI will take care of that for you.

YUMI clocked in at 17m46—slower than the first time I ran these tests some five years ago (it was 14m50s back then!), but still ahead of the rest.

5. Novicorp WinToFlash [No Longer Available]

Features: Multiboot, grub4dos, bootloader options, burning wizard, file systems, burning profiles, ISO auto-download

Novicorp WinToFlash is a popular ISO to USB utility that features a handy burning wizard. The wizard guides you through the burning process, although it isn’t unique to the utility (Rufus fills in all the information you need, for example). WinToFlash also allows you to create multiboot USBs as well as an auto-downloader for any ISO files you’re missing.

WinToFlash clocks in at 22m01, decent speed for a tool that guides you through the ISO to USB process.

6. UNetbootin

Features: grub4dos, ISO auto-download (Linux only), syslinux

UNetbootin is primarily a Linux LiveUSB burning tool, but it works sufficiently well with Windows that it deserves inclusion in this list. The UNetbootin utility isn’t flashy, but it does come with a few nifty features. For instance, it has an auto-download feature for Linux distributions, letting you select from a range of popular distros and system utility tools.

UNetbootin came home in 22m01, exactly the same as WinToFlash and again, a decent time for a useful tool.

The ISO-to-USB Winner Is…

The winner regarding speed is YUMI. The winner regarding features and ease of use is Rufus, which was only 3 minutes slower than YUMI. Furthermore, both burning tools cater to slightly different markets; Rufus is for one-off ISO to USB creation whereas YUMI is excellent for multiboot tools.

Let’s not discount the other USB to ISO tools. The range of burn times didn’t vary much, so it really boils down to the features you need and find in a specific utility.

Other ISO-to-USB Tools We Tested…

I tested many more ISO to USB tools for the sake of competition—and to bring you the best overall picture possible. There were a few tools that didn’t make the grade, for one reason or another. Here are the fallen few:

The Network Utility app is included with your Mac. It provides information and tools to help you with your network.

• XBoot is another multiboot tool featuring an inbuilt download, but other options were faster and somewhat easier to use. However, XBOOT’s QEMU function is excellent.
• WinToBootic fits comfortably into the basic features category and clocked a decent time, too.
• Passcape ISO Burner is a multifunction burning tool, but it wouldn’t work for me. I have read other positive reviews, so it could be worth a look for other individuals.
• ISO to USB is another very basic tool. However, it didn’t make the cut through a slow time and lack of features.
• FlashBoot has a decent UI and a burning wizard to guide you through, but I gave up on the test as it had not even hit 50% after nearly 40 minutes.
• UltraISO burned the ISO to USB at a reasonable speed and has the bonus of being able to mount ISOs before burning to check their files.

My MBA 2012 with OS X 10.9.4 Mavericks won't boot anymore - it simply freezes after the initial jingle. I already tried resetting NVRAM and SMC, but to no avail. I don't have any time machine backups.

However, I still have a disc image of Mavericks sitting on an external hard drive, a USB stick and access to a notebook with Windows 7.

I haven't yet found any tutorial on how to create a bootable USB drive on Windows in order to reinstall OS X on my beloved Macbook Air.

Any help would be greatly appreciated!

According to the first answer here, https://superuser.com/questions/383235/create-a-bootable-usb-drive-from-a-dmg-file-on-windows, there's a tool with a free trial called TransMac that can do it. Just make sure the USB drive is formatted with GPT and not MBR.

What might be easier, however, is that that model has support for Internet Recovery. If you boot holding Command-R and you have a WiFi connection, it can actually boot into recovery mode without a recovery partition on a drive (or even without a working drive).

Having said that, your description of a crash right after the boot chime could signify a more serious hardware problem and you may not be able to boot anything. If you boot holding the option key down, the startup disk selection screen should appear. If it crashes anyways, you may be looking at a hardware problem.

I know this question is old but it is still valid. I was never able to write a Mac installer image to my Flash Drive and have it bootable, unless I did it on a Mac. Using Michael D. M. Dryden's Link, I was able to use the Diskpart command to clean and prep a GPT partition on a flash drive for an OSX Mavericks install image.

I used TransMac on Windows 7 to restore the image file I had to the Flash Drive, it created a bootable Mac image on my flash drive. Someone had reported that the method for using DISKPART did not work, but I have done this twice and it works remarkably well, and it's the only method I could find to create a Mac-Bootable Flash. I've been trying to post this to confirm that it works for some time, I just hope it helps someone else, because it is a very easy solution.

Here are the Diskpart commands used to prep the Flash Drive, just to have them here in case my Link does not work:

(Find the disk number)

Is paint tool sai available for mac. How can the answer be improved?

Disk x is now the selected disk.

DiskPart succeeded in cleaning the disk.

DiskPart successfully converted the selected disk to GPT format.

Note: I use 'Rufus' for all other USB writing and formatting for Windows systems, it's a great app, but I had previously tried to format the drive as GPT using that, as a Fat32 partition. When I tried to inject the image, Transmac told me that the drive was 'write protected'. So basically, the USB drive cannot have any high level formatting, the Windows system should detect the drive as 'not formatted' for this to work, which it will if prepped right with Diskpart.

I was able to do this with Power ISO on Windows but it cost me $29.99

-- I created an ISO from the original install DVD and then went to tools => Create Bootable USB..Selected the OSX imageSelected the USB drive to create the bootable image onSelected RAW mode

I popped it in my Desklamp iMac (DVD Drive busted from toddlers -- majority of OS was trashed by 5yo) and boom ready to install. Best compression tool for pc.

I had this problem with a friend computer, it was an old iMac and I'll tell you it is not going to be easy.
The first thing you have to do is make sure what model you have (the year when your computer has been released) then check on the official apple website to see what is the latest macOS or Mac OS X version available for you computer.
In most of the new mac computer, you can just press cmd+r while booting and the mac will automatically download everything you need to install the system, but the oldest does not have this tool.
In this case, you have to download the dmg file, that can be found on the web, for example, one websites that provides some macOS and Mac OS X is this (for El Capitan, if you need another version, I'm sorry but you have to search for it).
Here things start to get a little tricky.
First of all you have to flash the image on a USB drive, I recommend etcher, that works on everything (Mac, Linux and Windows too) it's extremely easy to use and you just need to select the drive and the image and etcher will do everything by itself, plus it's free here.
When the USB drive is ready you can plug it in you mac and press alt (option) while booting, you have inserted a firmware password, it will ask you to unlock the firmware by inserting that password, else it will take you to all the bootable drives, including your USB device.
If you see the mac logo with a stop icon over it, it means that you downloaded a too new version that is not supported from your mac, else it will start.
When it start, it won't install, saying that the system can't verify the downloaded image, that's why you have to navigate on the 'utilities' menu on the top bar and open the terminal.
Now you have to choices, change the date & time, which can work, but may not.
That's basically because every image of mac has a certificate that can expire, so, if the certificate is expired you won't be able to make it work, unless you change the date (the date is different from mac version to mac version, so based on that you have to change it, usually just search for when was that version released and se the current date to that date or even one or two days later to make it work). Then try to install the system, if this does not work again, you can start the installation without verifying the image, but you should really trust the image you're using from being corrupted or modified (just to make sure the download went right, use the SHA-1 code to make the file has been downloaded right).
So, to proceed without verifying the image, from terminal, type in this command: sudo defaults write com.apple.frameworks.diskimages skip-verify true
then, start the installation. (Is possible that you won't need the sudo at the begin, in that case just remove it from the command and start from 'defaults')
Now you should be able to install macOS from a USB drive..
Just a little thing, make sure to have formatted the disk before proceeding, I would recommend to make a partition that takes the whole disk in mac Journaled format, then if you want you will be able to encrypt the disk (the installer will ask you to do that later), instead, if the disk was encrypted before, you will have to insert the encryption key of the disk to continue the installation process.
Really hope this help, I spent a lot of hours to do this on a really old iMac from 2008.. and now it works!
Good luck!

In my humble opinion, the easiest and a free solution for creating bootable drives is Rufus.

I've been struggling with the same problem but this works for me:

1. convert the .dmg image with power iso to iso
2. put the iso on a usb stick (drag it into your mac hard drive and mount it)
3. format your usb stick with the disk utility tool. (Make sure the usb is partitioned as mac bootable then use use the image recovery and put your mounted OS X iso into the source and your usb as the location.)
4. restart your computer while holding down the option key

You can create bootable USB drive on Windows using POWER ISO. You will be able to download a copy of old one version of powerISO by provided links this tutorial.

You need pen drive of more than 8 GB.
