Download and install ImgBurn. It’s a free application, but be careful during installation that you don’t install the 3rd party crap with it. Make sure you select “Custom” during each screen and deselect the crapware that tries to sneak in.
Plug the bootable stick into your machine.
Select a location to store the.iso file, and the name for it. In this instance I’m saving it to C: Temp New Folder and naming it Image. Click the Advanced tab, and then the Bootable Disc tab. Check the Make Image Bootable checkbox, and click the Browse button next to Boot Image. Browse to the Boot folder, and open the etfsboot.com file.
Open the ImgBurn application.
Now click on the “Create image file from files / folders”
- A blank USB flash drive with at least 5 GB of space or blank DVD (and DVD burner) if you want to create media. We recommend using a blank USB or blank DVD, because any content on it will be deleted. When burning a DVD from an ISO file, if you are told the disc image file is too large you will need to use Dual Layer (DL) DVD Media.
- First of all, make sure you’ve download a Windows 10, or Win7, 8 ISO image file on your Mac computer. Then you need to move ISO file to your USB drive by using Boot Cam. Now, insert your USB dive with at least 8GB to your Mac computer, make sure you’ve created a copy for your important file because your USB will be formatted.
Next to the Sources pane, click on the Browse Folder button.
Mac Os Iso Download
Select the folder or drive you want to convert. Unzip files free mac. In this instance I’m just imaging the D: drive.
Next, click on the Browse Folder button next to the Destination part.
Select a location to store the .iso file, and the name for it. In this instance I’m saving it to C:TempNew Folder and naming it Image.
Click the Advanced tab, and then the Bootable Disc tab.
Check the Make Image Bootable checkbox, and click the Browse button next to Boot Image.
Browse to the Boot folder, and open the etfsboot.com file.
Set the Developer ID to Microsoft Corporation and the Sectors To Load to 8. Leave 07C0 in the Load Segment part.
Now click the big Build button on the bottom-left.
Because we didn’t give the image a title, we get this error. Just click Yes to accept the default, or provide a name you desire.
And you’ll receive a confirmation about what will happen next. Click OK. In my case, I actually had to go back to the advanced tab as well to permit making an image that exceeds the ISO standard size (Mine’s over 10GB).
And then patiently wait…
And that’s it! Enjoy your newly created .iso file.
With a bootable Ubuntu USB stick, you can:
- Install or upgrade Ubuntu, even on a Mac
- Test out the Ubuntu desktop experience without touching your PC configuration
- Boot into Ubuntu on a borrowed machine or from an internet cafe
- Use tools installed by default on the USB stick to repair or fix a broken configuration
Creating a bootable USB stick is very simple, especially if you’re going to use the USB stick with a generic Windows or Linux PC. We’re going to cover the process in the next few steps.
Apple hardware considerations

There are a few additional considerations when booting the USB stick on Apple hardware. This is because Apple’s ‘Startup Manager’, summoned by holding the Option/alt (⌥) key when booting, won’t detect the USB stick without a specific partition table and layout. We’ll cover this in a later step.
