A typical CD-ROM holds around 741MB of data.
Unlike traditional audio or application CD-ROMs, bootable CDs contain special files that your computer can boot from just as it would a hard drive. Bootable CDs are easy to duplicate using CD-burners, but there are a number of reasons why you might want to directly copy the contents of a bootable CD to your hard drive. You can do this just as you would with any other disc using your computer’s CD-ROM drive.
1. Insert the CD-ROM into the CD-ROM drive on your computer. Make sure the computer is on and logged into Windows. Wait several seconds for the computer to recognize the disc.
2. Click the “Start” button and select “Computer.” Look for the CD under “Devices with Removable Storage.” The icon looks like a CD or DVD.
3. Right-click the CD-ROM icon and select “Open.” Windows will display the contents of the bootable CD.
4. Click “Organize” in the upper, left corner of the screen and choose “Select all” to select the entire contents of the disc. Press “Organize” again and click “Copy.”
5. Navigate to the folder on your computer where you wish to copy the CD files. Right-click and select “Paste.” Windows will transfer the bootable CD contents to your computer.
