ISO files are exact copies of a DVD or CD. They are useful for archiving and sharing discs and you don't have to worry about scratches or other damage. You can create ISO images with any operating system, although Windows users will need to download a program.
Method 1 of 3: Windows
Step 1. Download and install an ISO or disk image creation program, such as InfraRecorder
Windows itself does not have the ability to create ISO files, so you will have to use a separate program. There are many programs that can do this, but they often contain advertisements and other junk as well. InfraRecorder is a free, open source disk image creation program with no ads. No one is trying to profit from the fact that you download and install it.
You can download InfraRecorder for free from infrarecorder.org. Download the installer and open it to install it. By default, a shortcut is created on your Desktop and in the Start menu
Step 2. Insert the drive you want to make a copy of
You can create an ISO from any CD or DVD. The resulting disk image will be the same size as the data on the disk (up to 800 MB on a CD, or 4.7 GB on a DVD).
Step 3. Launch InfraRecorder
A small InfraRecorder window will appear.
Step 4. Select 'Read Disc'
This will open the 'Copy to Disc Image' window.
Step 5. Select your disk drive from the drop-down menu
Choose the drive where you placed the disc.
Step 6. Click on the ' button
.'. next to the 'Image' field. This allows you to choose where to save the new ISO file, and under what name.
By default, it is saved in the Documents folder
Step 7. Click 'OK' to create the ISO file
How long this will take depends on the size of the disk and the speed of your disk drive. When the process is complete, you will find the ISO file in the location you set in the previous step.
Method 2 of 3: Mac OS X
Step #1. Open the Disk Utility
You can create disk images from any of your CDs or DVDs using the Disk Utility. You can find it in the Utilities folder in the Applications folder. You can also press ⌘ Command+Space and then enter "disk utility" to search for it.
Step 2. Insert the disc you want to copy
Insert the CD or DVD you want to burn a disc image from.
Step 3. Click on the File menu and select the 'New Disk Image' option
This will open a submenu.
Step 4. Select 'Disk image of [device name]'
[device name] in this case is the disc drive containing the CD or DVD.
Step 5. Give the disk image a name and save location
Saving the file to your Desktop will make it easier to find later.
Step 6. Make sure 'DVD/CD Master' is selected as 'Structure'
This will make a correct copy of the disk.
Step 7. Click 'Save' to start creating the disk image
How long this takes depends on the size of the disk and the speed of your disk drive.
Step 8. Locate the finalized CDR file
Your Mac will create a disk image in CDR format. This is fine if you only want to use it on a Mac, but you can convert it to an ISO file if you want.
Step 9. Open the Terminal
You can convert the CDR file to an ISO file using a simple Terminal command. You can find the Terminal in the Utilities folder.
Step 10. Convert the CDR file to an ISO file
Enter the following command to convert the file, changing the path to the path to your own file:
hdiutil convert ~/Desktop/original.cdr -format UDTO -o ~/Desktop/converted.iso
Method 3 of 3: Ubuntu/Linux
Step 1. Insert the disc you want to copy
You can use the tools that come with Ubuntu to create ISO files, without the need for additional software.
Step #2. Open Brasero
This program is part of Ubuntu, and can quickly create ISO files from discs.
You can find Brasero by pressing ⊞ Win and then entering 'brasero'
Step 3. Select the 'Disk Image' option
A CD/DVD copy window appears.
Step 4. Select your disk drive from the first menu
If you only have one disk drive, it will be selected by default.
Step 5. Choose 'Image File' via the option 'Select a disc to write to'
This creates a disk image file from the original disk, rather than copying it to a blank disk.
Step 6. Click on 'Create Image'
You will be prompted to name the disk image and select the location where you want to save the file. After that, Ubuntu will create the ISO file of the disk inserted in the computer.
Step 7. Use the Terminal to create an ISO file
If you prefer to work with the Terminal, you can create an ISO file with a single command. Open the Terminal by pressing Ctrl+Alt+T and entering:
- sudo dd if=/dev/cdrom or=/home/username/image.iso
- Replace /dev/cdrom with the path to your disk drive. Replace the path of the ISO file with the one where you want to save the file.
