This post will teach us how to create ISO image from CD for Windows, Mac, and Linux. You can also learn how to create a bootable rescue media via EaseUS Todo Backup.
If you have old CDs or DVDs, it's the perfect time to put the data into an ISO (a disc image) file. Why ISO? ISO or disc images are single files that perfectly encapsulate all the data on the disk. These features make ISO files ideal, as you can later burn them onto a hard drive or new disk or even mount them on a USB drive. This article from EaseUS will tell how to create ISO image from CD for Windows/Mac/Linux.
Computers are often prone to accidents or virus attacks, which can result in data loss. The best way to protect your PCs from boot failures or data loss is to back up the Windows system and create a bootable rescue disk. EaseUS Todo Backup, a professional backup and recovery tool, helps you create a bootable rescue disk CD/DVD with simple steps.
EaseUS backup software can help you back up your files, systems, disks, and computer apps, and save them in various locations. It can help you install Windows after replacing the motherboard and clone a hard drive to another. In addition, it can also help you put an IOS file on a USB drive or CD/DVD and back up your Windows to a DVD drive.
Todo Backup also helps you to create an ISO image from a USB drive and offers advanced backup and cloud storage options to safeguard data.

Step 1. Prepare a USB drive which can be written and read.
Step 2. Launch and install EaseUS Todo Backup on the Computer B.
Step 3. Find and click "Tools" and choose "Create Emergency Disk".
Step 4. Choose the Boot disk location. You can create an ISO file, a bootable USB or CD/DVD disc.
Step 5. Then click "Create" to start.
There is no built-in utility on Windows to create an ISO file. We can use third-party software to convert the data on the CD to an ISO file. The guide uses BurnAware Free, a free ISO creator, to create an ISO image from a CD.
Step 1. Download and Install BurnAware Free on your computer.
Step 2. Insert the CD you want to create the ISO file into the computer.
Step 3. Launch BurnAware and click on the ISO image from the left panel.
Step 4. Select Copy to ISO (copy disc to disk image), and click the drop-down to set the Source as the CD or DVD.
Step 5. Click Browser and select the Disk Image path (where you want to store the ISO file). Give it a name and click Save.
Step 6. Click Copy, and the ISO file creation process starts.
Wait for the software to create the ISO file. You can see the "Copy process completed successfully" message. Eject the disc and check the file integrity by mounting the ISO.

MacOS comes with built-in features for creating disk images from CD/DVD. The Disk Utility tool, which can create DMG (Mac stores disk images in DMG format) files from CDs, is available on MacOS. By default, the disk image is stored as DMG.
DMG roughly translates as disk images. It is unique to Macs and does not support reading or writing on other OSs. Since DMG files are unique to macOS, they do not support other OS. The following guide helps you convert a CD/DVD into an ISO file. Also, find out how to convert the DMG files to ISO later in this section.
Step 1. Create a new folder (name is something like ISO image, etc).
Step 2. Find the disc (CD/DVD) contents and copy them to the new folder.
Step 3. Navigate to Finder > Applications > Utilities > Disk Utility.
Step 4. Go to File > New Image > Image from the folder.
Step 5. Select the folder you created earlier and set a file name for the disk image.
Step 6. Change the image format to DVD/CD master and click Save. Wait for the process to complete and click Done.
The process above creates a DMG file. To convert it to an ISO file, follow the below steps.
Step 1. Open the terminal and use the cd command to switch to the directory/folder the DMG file is saved to:
Step 2. Execute the following command to convert the DMG file to ISO.
Replace the [filename] with the DMG file. Once the OS converts the file to ISO format, the ISO file is ready to mount and open.
If you have Linux/Ubuntu, you have two options: the built-in disk management tool and the terminal. If you can manage command-line tools, you can go with the terminal.
Insert the CD/DVD on the computer. Ensure the media is not mounted on the device. Depending on the Linux version you are using, execute the command below:

Now, without mounting the disk, execute the comment below to create an ISO image.
Note: Replace the username with the Linux username.
After executing the command, wait for the disc to stop spinning. Then, you will have the CD in ISO image format on the drive.
Linux has a disk utility named Disks. This feature helps us create ISO files from a CD/DVD.
Step 1. Launch the Disks app after you insert the optical drive (CD/DVD).
Step 2. If the OS recognizes the disc, it will appear on the left panel.
Step 3. Click Stop to unmount it, click the three dots above, and select Create Disk Image.
Step 4. Give it a file name, change the extension to ".iso" from ".imo," and set the location before clicking Start Creating.
Step 5. Now, wait for the process to complete. After completing it, close the Disks app and eject the disk.
Once you create an ISO file, you can store it on a hard drive, USB, or the network. The disc image is available for use. So, that's all about how to create ISO image from CD or DVD on various operating systems. If you are facing issues with the CD or creating the ISO file, it is better to back up the Windows System and drive content in advance. With EaseUS Todo Backup, creating a bootable rescue disk becomes a three-step process. Try it now, and protect your data.
