Convert to ISO
Linux doesn’t much care for DMG files. Sure, it’ll play nice with them. But we don’t just want to play nice. We want to copy a DMG image to a USB drive and keep it as verbatim as computationally possible. In order to do this, we’re first going to convert the image to a format that’s a little more universal: ISO.
We’re going to use dmg2img to convert the DMG to an ISO image. If you already have dmg2img, great. If not, install it using your distribution’s native package management system.
On Ubuntu, you’d do it like this:
Once you have dmg2img installed, begin converting the DMG file:
After a few minutes, you should have a second file called image.img. This file can be used like an ISO. All we have to do is change the extension. Use mv to do this:
Make sure you specified “image.img” and not “image.dmg”! Working with three different file extensions can get kind of confusing.
Ok, so we should now have a file called “image.iso” which is just “image.img” with a different extension.
Now we want to write “image.iso” to our USB drive. I used “lsblk” to figure out how the system was identifying my drive. The lsblk command lists all disks connected to the system. It’s usually pretty easy to figure out which disk is which based on their size. Just be sure you’re sure. This process is going to overwrite the target disk with the contents of our DMG image file. Any preexisting files on the target disk will be lost. As usual, make sure you have a proper backup.
Make sure the target drive isn’t mounted. Unmount the drive with your distribution’s GUI.
Or you could just unmount it from the terminal:
Most systems seem to mount external drives in /media. Sometimes the drive might be mounted in /mnt or elsewhere.
Write the ISO image to the USB drive like this:
Replace “X” with the appropriate letter. For example “/dev/sdb”. Be sure to use the drive directly and not a partition within the drive. For example, don’t use “/dev/sdb1”.
This will probably take a little while to complete. I’m using a Kingston DataTraveler DTSE9 and it took about 24 minutes 30 seconds to write 4.9GB.
Your new USB stick should now be bootable, assuming that was the intended purpose of the DMG.
A disk image or ISO file can be used for a variety of purposes, one of the most ubiquitous of which is to install an operating system on a computer. However, the ISO file – which is the key element – and the USB flash drive – which is the medium of delivery – must adhere to specific respective standards. If that doesn’t happen, any number of errors could crop up.
In this article, we’ll outline some of these common errors when creating a bootable USB installer using a Windows ISO file. We’ll also offer up a great tool for burning ISO files to USB drives and show you how it’s done – and why the tool goes far beyond its primary use as an ISO burner application.
Common Issues when Burning ISO Files
Invalid ISO File – The most common reason ISO files fail to burn properly is because of the files themselves. That’s why experts recommend that you always do a hash check for your ISOs before attempting to burn media or create a bootable installer no matter whether it’s on USB or a physical disk. After all, it doesn’t matter if you have the most expensive or sophisticated ISO burner in the world if the source file is corrupt or damaged in any way, right? So do a checksum to see if the file components are as they should be. Here’s a resource that shows you how.
Wrong Type of Writing Software – Unless you’re using an authoring tool that’s specifically designed to create bootable media like Windows Media Creation Tool, you’re wasting your time. Creating a bootable USB requires a disk authoring utility. You can use Microsoft’s own Media Creation Tool for this, or you can choose a more dependable option that has a much higher burn success rate.
Inadequate Space on your USB – If you’re creating an installer for the 64-bit version of Windows 10, as an example, you’ll need at least 6 GB of space on your USB. The May 2019 update is about 4.6 GB; no surprises there because Windows 10 is known for coming with a lot of bloatware that people don’t always need.
Corrupted Flash Drive – If your USB stick is corrupted, that could also lead to the burned ISO file not working as it should. As a best practice, make sure you fully re-format your drive before creating a Windows installer, and that the drive is partitioned according to the OS version you plan to put on it. Most of the top ISO burning tools UUByte ISO Editor or even the best open-source tools will format your drive based on the specific ISO being burned.
Which brings us to why you need such a robust tool like the UUByte ISO Editor.
