What's the best way to force an ISO to "burn" a USB drive on a Mac? Recovering using Disk Utility does not work.

ISO – ubuntu mini.iso. This is a minimalist ISO setup for installing ubuntu. It must be bootable on the PC. I'm trying to install ubuntu on a PC that doesn't have a CD-ROM. The only other computer I have is a macbook.

7 Solutions collect form web for “How to burn an ISO to a USB drive in Mac OS X?”

Directly from How to Install Ubuntu on a MacBook Using the USB Stick Page (My Formatting):

Upload the required file
Open a terminal (in /Applications/Utilities/ or prompt Terminal in the spotlight)
Convert the .iso file to .img using the convert hdiutil option (e.g. hdiutil convert -format UDRW -o ~/path/to/target.img ~/path/to/ubuntu.iso)
Note. OS X tends to automatically put the ending .dmg in the output file. Remove the .dmg extension as needed, mv ~/path/to/target.img(.dmg,)
Run diskutil list to get the current list of devices.
Insert flash drive
Run diskutil list and locate the device node assigned to your flash /dev/disk2 (e.g. /dev/disk2)
Run diskutil unmountDisk /dev/diskN (replace N with the disk number from the last command, in the previous example N would be 2)
Execute sudo dd if=/path/to/downloaded.img of=/dev/rdiskN bs=1m (replace /path/to/downloaded.img with sudo dd if=/path/to/downloaded.img of=/dev/ rdiskN bs=1m path where the image file is located, for example./ubuntu.img Or./ubuntu.dmg).
Using /dev/rdisk instead of /dev/disk may be faster.
- If you see the error dd: Invalid number "1m" you are using GNU dd. Use the same command, but replace bs=1m with bs=1M .
- If you see the error dd: /dev/diskN: Resource busy, make sure the disk is not in use. Run DiskUtility.app and unmount (do not remove) the drive.
Run diskutil eject /dev/diskN and remove the flash media when the command is completed
Restart your Mac and hold Alt while the Mac reboots to select the USB drive

Note. On new Mac computers, you Maybe You will need to install an EFI boot manager to boot from USB.

1. We use MAC OS

In all cases, to complete the task we will need an empty flash drive with a capacity of at least 8 GB, as well as an Internet connection. If you use MAC OS, you also need an Apple ID account.

The step-by-step process for creating a boot drive is as follows:

Download the system image from apple.com. There is always the latest version. Usually on the main page there is promotional material for the OS and the inscription “Update your system right now.” It can also be found on the App Store. To do this, use the search. Apple companies often give away their latest creations for free.
Insert the flash drive. Run the downloaded image. This is a special utility for creating bootable media. In the left panel, select the inserted drive. Go to the "Partition" tab.
Under “Partition Layout”, select “1 Partition”. It is also advisable to indicate the name of the flash drive. It is most convenient to name it according to the name of the operating system. In our case it is “El Captain”.
In addition, indicate the format next to the “Format” inscription “Mac OS Extended (Journaled)” and the size of the flash drive - enter as much as is on the media. Click Apply.

Now go back to the downloaded folder and launch the terminal. In it, enter the command shown in Figure 2. It can also be seen in this file.

Wait approximately 15 minutes. After this, the process will be completed and you will have bootable media ready to install the operating system.

Clue: To boot from the resulting media, connect it to your computer while holding down the Alt button. Then simply follow the installer's instructions.

As you can see, everything here is extremely simple. Difficulties arise if you are not able to use MAC OS to complete the task. Then you will have to resort to “workarounds”.

2. We use Windows

In this case, the installation image from the App Store will not work. You need to search on torrent trackers or regular sites. And then there are two options - either you will find the image in .dmg format, or in .iso format.

In the first case, you need to do this:

Download and install the TransMac program on your computer. The best way to do this is on the website acutesystems.com (it’s official). The program is paid, but it has a trial period of 15 days. During this time, you can manage to create many flash drives.
In the left panel, select the flash drive that you are going to make bootable. Right-click on it and click “Format Disk for Mac” in the drop-down list. A prompt will appear in which you simply need to click “Yes” or “OK”.
Once formatting is complete, right-click on the drive again, but now select “Restore with Disk Image.”
In the window that appears, under the inscription “Disk Image to restore”, indicate the path to the .dmg file that you downloaded earlier. Click OK. In all subsequent warnings, also click “OK” or “Yes”. Everywhere they talk about the fact that all data will be lost, and the image will be installed on the selected disk. But that's what we need.

In the future, use the flash drive in the same way as when creating one in MAC OS, that is, insert it into the computer and hold down “Alt”. The corresponding menu will appear and the OS can be easily installed.

If you managed to find an image in .iso format (which is most likely), then you have a huge variety of options for creating a bootable drive with it. And they are all absolutely free. For example, you can use Rufus.

To do this, do this:

Download the program from the official website (rufus.akeo.ie) and run it on your computer.
In the “Device” field, select the flash drive that you are going to make bootable. You can change the remaining fields up to the one related to the name at your discretion. If you don’t understand, it’s better not to touch them at all.
In the New Volume Label field, enter the name of your media. This is not necessary, but it is better to name the drive accordingly to make it easier to deal with later.
Check the boxes next to “Quick format” and “Create a boot disk.” To the right of the last one, select “ISO image” and click on the button in the form of a disk drive. Specify the path to the downloaded image.
Click "Finish" and wait for the process to complete.

In the same way, you can use the following programs:

SARDU and others.

Some of them are paid, so be careful.

3. Use Linux

In Linux and Ubuntu everything is much simpler. There is no need to use any additional programs here. All you need is a terminal, the same empty flash drive and the downloaded image.

Important! To complete the task from Linux, you must have an image in .iso format. Others may not be suitable. However, some of the .iso files may not be suitable, but if you download the images in other formats, they definitely cannot be used.

If all this is there, insert the USB flash drive, launch the terminal and do the following:

Enter the command "diskutil list". After completing it, you will see a complete list of disks that are currently in use on the computer. Find your drive there.
Enter the command "diskutil unmountdisk [media name]". That is, if the flash drive is called “/dev/mydisk”, the command will look like “diskutil unmountdisk /dev/mydisk”.
Enter the command “sudo dd if=[folder where the image in .iso format is located] of=[name of the removable drive] bs=1024”. Then if the folder with the image is called “z:/papka/obraz”, then the command will look like “sudo dd if= z:/papka/obraz of=/dev/mydisk bs=1024”.
Wait for the creation process to complete.

As you can see, in Linux it is easiest to complete the task.
