- Possibly the best and most complete tool to create bootable USB drives from ISO files in.
- If you want to use your USB stick with an Apple Mac, you will need to restart or power-on the Mac with the USB stick inserted while the Option/alt (⌥) key is pressed. This will launch Apple’s ‘Startup Manager’ which shows bootable devices connected to the machine.
- Macworld also has bootable-install-drive instructions for: mac OS High Sierra (10.13) El Capitan (OS X 10.11) Yosemite (OS X 10.10) Mavericks (OS X 10.9).
Connect the external drive to your Mac, and make a note of the external drive's name as it appears within macOS. This is important, as using the wrong name could lead to another connected drive. To make a Windows 10 bootable USB, then you need to choose the first option “Burn” and next. As you can see, you’re allowed to create a Windows 10 bootable disk with USB drive or DVD/CD, here, just insert your USB drive to your Mac, then import ISO file by clicking browse button.
I needed to run a BIOS flash utility that was only available for DOS. To complicate matters, the server I needed to run it on doesn’t have a floppy or CD-ROM drive. I figured I’d hop on the Internet and download a bootable USB flash drive image. Right? Wrong.
I found a lot of instructions for how to make such an image if you already have a running Windows or Linux desktop, but they weren’t very helpful for me and my Mac. After some trial and error, I managed to create my own homemade bootable USB flash drive image. It’s available at http://www.mediafire.com/?aoa8u1k1fedf4yq if you just want a premade ready-to-download file.
If you want a custom version, or you don’t trust the one I’ve made – and who’d blame you? I’m some random stranger on the Internet! – here’s how you can make your own bootable image under OS X:
- There are a lot of steps, but they’re easy! I wanted to err on the side of being more detailed than necessary, rather than skipping “obvious” steps that might not be quite so easy for people who haven’t done this before.
- Download VirtualBox. I used version 4.1.4. The version available to you today might look different but should work mostly the same way.
- Open the “VirtualBox-[some-long-number]-OSX.dmg” disk image.
- Double-click the “VirtualBox.mpkg” icon to run the installer.
- Click “Continue”.
- Click “Continue”.
- Click “Install”.
- Enter your password and click “Install Software”.
- When it’s finished copying files, etc., click “Close”.
- Download the FreeDOS “Base CD” called “fdbasecd.iso”. Note: the first mirror I tried to download from didn’t work. If that happens, look around on the other mirrors until you find one that does.
- Open your “Applications” folder and run the “VirtualBox” program.
- Click the “New” button to create a new virtual machine. This launches the “New Virtual Machine Wizard”. Click “Continue” to get past the introduction.
- Name your new VM something reasonable. I used “FreeDOS”, and whatever name you enter here will appear throughout all the following steps so you probably should, too.
- Set your “Operating System” to “Other”, and “Version” to “DOS”. (If you typed “FreeDOS” in the last step, this will already be done for you.) Continue.
- Leave the “Base Memory Size” slider at 32MB and continue.
- Make sure “Start-up Disk” is selected, choose “Create new hard disk”, and continue.
- Select “File type” of “VDI (VirtualBox Disk Image)” and continue.
- Select “Dynamically allocated” and continue.
- Keep the default “Location” of “FreeDOS”.
- Decision time: how big do you want to make your image? The full install of FreeDOS will take about 7MB, and you’ll want to leave a little room for your own files. On the other hand, the larger you make this image, the longer it’ll take to copy onto your USB flash drive. You certainly don’t want to make it so large that it won’t actually fit on your USB flash drive. An 8GB nearly-entirely-empty image will be worthless if you only have a 2GB drive. I splurged a little and made my image 32MB (by clicking in the “Size” textbox and typing “32MB”. I hate size sliders.). Click “Continue”.
- Click “Create”.
- Make sure your new “FreeDOS” virtual machine is highlighted on the left side of the VirtualBox window.
- On the right-hand side, look for the section labeled “Storage” and click on the word “Storage” in that title bar.
- Click the word “Empty” next to the CD-ROM icon.
- Under “Attributes”, click the CD-ROM icon to open a file chooser, select “Choose a virtual CD/DVD disk file…”, and select the FreeDOS Base CD image you downloaded at the beginning. It’ll probably be in your “Downloads” folder. When you’ve selected it, click “Open”.
- Back on the “FreeDOS – Storage” window, click “OK”.
- Back on the main VirtualBox window, near the top, click “Start” to launch the virtual machine you just made.
- A note about VirtualBox: when you click the VM window or start typing, VirtualBox will “capture” your mouse cursor and keyboard so that all key presses will go straight to the VM and not your OS X desktop. To get them back, press the left [command] key on your keyboard.
- At the FreeDOS boot screen, press “1” and [return] to boot from the CD-ROM image.
- Hit [return] to “Install to harddisk”.
- Hit [return] to select English, or the up and down keyboard arrow keys to choose another language and then [return].
- Hit [return] to “Prepare the harddisk”.
- Hit [return] in the “XFDisk Options” window.
- Hit [return] to open the “Options” menu. “New Partition” will be selected. Hit [return] again. “Primary Partition” will be selected. Again, [return]. The maximum drive size should appear in the “Partition Size” box. If not, change that value to the largest number it will allow. Hit [return].
- Do you want to initialize the Partition Area? Yes. Hit [return].
- Do you want to initialize the whole Partition Area? Oh, sure. Press the left arrow key to select “YES”, then hit [return].
- Hit [return] to open the “Options” menu again. Use the arrow keys to scroll down to “Install Bootmanager” and hit [return].
- Press [F3] to leave XFDisk.
- Do you want to write the Partition Table? Yep. Press the left arrow to select “YES” and hit [return]. A “Writing Changes” window will open and a progress bar will scroll across to 100%.
- Hit [return] to reboot the virtual machine.
- This doesn’t actually seem to reboot the virtual machine. That’s OK. Press the left [command] key to give the mouse and keyboard back to OS X, then click the red “close window” button on the “FreeDOS [running]” window to shut it down. Choose “Power off the machine” and click “OK”.
- Back at the main VirtualBox window, click “Start” to re-launch the VM.
- Press “1” and [return] to “Continue to boot FreeDOS from CD-ROM”, just like you did before.
- Press [return] to select “Install to harddisk” again. This will take you to a different part of the installation process this time.
- Select your language and hit [return].
- Make sure “Yes” is selected, and hit [return] to let FreeDOS format your virtual disk image.
- Proceed with format? Type “YES” and hit [return]. The format process will probably finish too quickly for you to actually watch it.
- Now you should be at the “FreeDOS 1.0 Final Distribution” screen with “Continue with FreeDOS installation” already selected. Hit [return] to start the installer.
- Make sure “1) Start installation of FreeDOS 1.0 Final” is selected and hit [return].
- You’ll see the GNU General Public License, version 2 text. Follow that link and read it sometime; it’s pretty brilliant. Hit [return] to accept it.
- Ready to install the FreeDOS software? You bet. Hit [return].
- Hit [return] to accep the default installation location.
- “YES”, the above directories are correct. Hit [return].
- Hit [return] again to accept the selection of programs to install.
- Proceed with installation? Yes. Hit [return].
- Watch in amazement and how quickly the OS is copied over to your virtual disk image. Hit [return] to continue when it’s done.
- The VM will reboot. At the boot screen, press “h” and [return] to boot your new disk image. In a few seconds, you’ll see an old familiar “C:” prompt.
- Press the left [command] key to release your keyboard and mouse again, then click the red “close window” icon to shut down the VM. Make sure “Power off the machine” is selected and click “OK”.
- Open a Terminal.app window by clicking the Finder icon in your dock, then “Applications”, then opening the “Utilies” folder, then double-clicking “Terminal”.
- Copy this command, paste it into the terminal window, then hit [return]:
This will turn your VirtualBox disk image file into a “raw” image file on your desktop named “freedos.img”. It won’t alter your original disk image in any way, so if you accidentally delete or badly damage your “raw” image, you can re-run this command to get a fresh, new one.
- Plug your USB flash drive into your Mac.
- If your Mac can’t the drive, a new dialog window will open saying “The disk you inserted was not readable by this computer.” Follow these instructions:
- Click “Ignore”.
- Go back into your terminal window and run this command:
- You’ll see a list of disk devices (like “/dev/disk2”), their contents, and their sizes. Look for the one you think is your USB flash drive. Run this command to make sure, after replacing “/dev/disk2” with the actual name of the device you picked in the last step.
Make sure the “Device / Media Name:” and “Total Size:” fields look right. If not, look at the output ofdiskutil list
again to pick another likely candidate and repeat the step until you’re sure you’ve picked the correct drive to complete eradicate, erase, destroy, and otherwise render completely 100% unrecoverable. OS X will attempt to prevent you from overwriting the contents of drives that are currently in use – like, say, your main system disk – but don’t chance it. Remember the name of this drive! - If your Mac did read the drive, it will have automatically mounted it and you’ll see its desktop icon. Follow these instructions:
- Go back into your terminal window and run this command:
- Look for the drive name in the output of that command. It will have the same name as the desktop icon.
- Look for the name of the disk device (like “/dev/disk2”) for that drive and remember it (with the same warnings as in the section above that you got to skip).
- Unmount the drive by running this command:
- This is not the same as dragging the drive into the trash, so don’t attempt to eject it that way.
![Mac Mac](/uploads/1/2/6/5/126528566/778077586.png)
- Go back to your terminal window.
- Run these commands, but substitute “/dev/fakediskname” with the device name you discovered on the previous section:
- After the last command finishes, OS X will automatically mount your USB flash drive and you’ll see a new “FREEDOS” drive icon on your desktop.
- Drag your BIOS flasher utility, game, or other program onto the “FREEDOS” icon to copy it onto the USB flash drive.
- When finished, drag the “FREEDOS” drive icon onto the trashcan to unmount it.
- You’re finished. Use your USB flash drive to update your computer’s BIOS, play old DOS games, or do whatever else you had in mind.
- Keep the “freedos.img” file around. If you ever need it again, start over from the “Prepare your USB flash drive” section which is entirely self-contained. That is, it doesn’t require any software that doesn’t come pre-installed on a Mac, so even if you’ve uninstalled VirtualBox you can still re-use your handy drive image.
If you own a Mac and would like to run Windows on your device, you will need to create a Windows 10 bootable USB. You can use your Mac, even if it is running Mac OS to create this. It can also be useful if you want to install Windows on a new PC that you have built or if you have replaced the hard drive on your PC and you need to reinstall Windows 10. There is a range of other reasons as to why you may need to create a Windows 10 bootable USB. This article will show you how to create a Windows 10 bootable USB in 4 different ways.
![Usb Usb](/uploads/1/2/6/5/126528566/142111582.jpg)
Method 1: Use Boot Camp Assistant on Mac
In order to create a bootable USB using Boot Camp, you will require a USB that has 16GB of storage, or more. Please note that Boot Camp is not supported in macOS Mojave and later.
- Insert a USB drive into your Mac.
- Open Bootcamp Assistant on your Mac.
- Tick the box for 'create a Windows 7 or later version install disk' and uncheck the 'Install Windows 7 or later version' option. Then click on continue.
- Download a Windows 10 .iso file from the Microsoft website or another reliable site. Keep this in a location that is easily found (such as the Downloads folder).
- Bootcamp will locate the downloaded iso file automatically however if it is not found, you can use the'choose' button to locate it manually.
- Click on Continue and wait until the USB is formatted and set up to become a bootable drive.
- Once the process has been completed by the Bootcamp Assistant, the USB will have been renamed. You can now quit Bootcamp and then Eject the USB to safely remove it.
Make Bootable Usb Mac Os
This will have created a Windows 10 bootable USB using a Mac that can now be used on your PC.
Method 2: Use Disk Utility on Mac
If you are running an older version of Mac, you can use the built-in Disk Utility app to create a Windows 10 bootable USB drive. As this is only compatible with older versions of Mac OS, it is recommended that you use an alternative method.
- Plug in your USB and open the disk utility tool.
- Right-click on your USB drive on the left and format the drive (which will remove all the data) with MS-DOS (FAT).
- Drag the Windows ISO file to the USB drive and the ISO file will begin to write on the USB.
Method 3: Use UNetbootin on Mac
UNetbootin is free to use and allows you to make a bootable USB drive for Windows 10 using your Mac. Again, like the first method, you will need a USB drive (with a capacity of 16GB as a minimum recommendation) and you will also need to download the .iso file and keep it in a memorable location.
- Plug in your USB drive into your Mac.
- Open Disk Utility and select your USB drive on the left. Click on the info button and write down the device name.
- Download and install the UNetbootin utility.
- Choose the 'Diskimage' button and then click on the '…' button to select the iso file that you have downloaded.
- Set the Type as USB Drive and select the device name of your USB drive that you have noted down earlier.
- Click OK and wait for the USB to be formatted to a bootable drive.
Method 4: Use Terminal on Mac
The Terminal app is more complicated to use than other methods however it does not require you to use a third-party application in order to create a Windows 10 bootable USB drive. Again, you will need a USB drive.
Creating A Bootable Usb For Mac
- Connect your USB drive to the Mac and then launch Terminal.
- Type 'diskutil list' and hit the enter/return key to see a list of all connected drives.
- Identify your USB drive and note down the name, such as disk3.
- Run the command 'diskutil eraseDisk MS-DOS 'WINDOWS10' GPT disk3' without the quotation marks and you can replace the '3' at the end with the correct number.
- Download the iso file for Windows 10 and save it in the Downloads folder if it hasn’t been saved there already.
- Mount the .iso image by using the command 'hdiutil mount ~/Downloads/WINDOWS10IMAGE.iso' where you can replace the 'WINDOWS10IMAGE with the name of your downloaded file. Note the name of the mounted iso, which can be found by looking at the terminal. It will be similar to /Volumes/MOUNTED-NAME.
- Next, run the command 'cp -rp /Volumes/MOUNTED-ISO/* /Volumes/WINDOWS10/' where you can replace MOUNTED with the name of your mounted ISO.
- Once the command has finished and your files have been moved over to the USB drive, you will need to run the command 'hdiutil unmount /Volumes/MOUNTED-ISO', again replacing the word MOUNTED with the correct name.
- Close the terminal and eject your USB drive. This can now be used as a bootable drive.
