How to Make Bootable Image (.iso) from CD/DVD Disc

When you purchased a copy of Windows 10 from Microsoft online store, a physical DVD will be shipped to you in default. It is one being used to install a valid Windows 10 operating system. However, modern computer don't come with a DVD drive sometimes, so the DVD would be useless in such a case. However, you can make a bootable image (.iso) from that DVD, so you can burn the ISO to USB or unpack the ISO and directly install Windows 10 from there.

Creating a bootable image from a DVD is a fairly simple process if you know what you're doing, but it's not the same thing as simply copying the contents of a DVD to another file. An ISO file is essentially a copy of the contents of a DVD. However, for loading an operating system on to a PC from the ISO file or a DVD containing the bootable media, the ISO file itself must contain the boot information. On Windows, you will need special software to do this since it doesn't come by default. Here are 3 useful tools to help you create a bootable image file from a DVD.

Part 1: How to Make Bootable Image (.iso) from DVD on Windows 10

InfraRecorder is an open-source utility and does not contain any adware, which distinguishes it from the mass of ad-ridden free apps available for download. Simply go to infrarecorder.org and download, then install the software on your PC.

Launch the application, and you'll see a small window with several options. Click on the "Read Disc" option and insert the DVD from which you want to create the image file. This will take you to another page where you need to select the source file (DVD) and where you want the image file to be stored. The Default is in the Documents folder, but you can specify a different one.

Once that's done, click on "OK" and the image file creation process will begin. The ISO file will be roughly the same size as the DVD contents, and depending on your drive speed and the size of the disc, this could take some time. The ISO file will now be in the location that you specified.

Part 2: How to Create Bootable Image from DVD on Mac

On a macOS machine, the process is a lot simpler since you won't need any additional tools. The Disk Utility application on an iMac or MacBook will allow you to create bootable image files from any CD or DVD.

Step 1: Launch the program from the Utilities folder or simply press Command + Spacebar and type in Disk Utility.

Step 2: Now, go to File >> New Image >> Image from DVD Drive. You will now see a popup asking you to specify the name and location of the image file. Saving it on your Desktop is recommended, since it will be easy to find later on. For the image format, select the DVD/CD Master option. Now click on "Save".

Step 3: The above process will create a file in the CDR (.cdr) format. You can only use this on a Mac system, so if you want to use it on Windows you will need to convert it to an ISO file. You can do this by going to Terminal and typing in the following command:
hdiutil convert ~/Desktop/GBMB.cdr -format UDTO -o ~/Desktop/GBMB.iso

That will convert your .cdr file to .iso. In the command above, replace"~/Desktop/GBMB.cdr" with the file path of your CDR file and replace the second section with the desired name and location of the ISO file.
