How to Mount a USB Flash Drive As a CD-R?

By Kevin Floyd

USB Flash drives can be used as a CD-R if you don't have access to a CD burner or are working with a computer that doesn't have a working CD drive. You can mount and boot from the USB Flash Drive much like a CD or even use it to play music on certain stereos.

Mount a USB Flash Drive as a Data CD-R

Step 1

Connect a USB Flash drive to your computer. If this is the first time using the drive, you may be asked to format it. For mounting a USB like a CD-R, pick an FAT format. Right-click on the drive, select "Properties" and write down the "File System." Right-click on the drive again, select "Format," choose the correct FAT format and click "OK."

Step 2

Insert the CD that you wish to copy. Right click on the disc and choose "Make CD/DVD Image" and select a location on your hard drive to save the file. If you do not have the option to make a CD image, then you need to update your operating system or install an application like Nero or Magic ISO Maker.

Step 3

Copy the ISO file to your USB Flash drive by clicking and dragging it. Do not add any additional files to the drive if you want to use it as a boot disc. Restart your computer and reconnect your USB Flash drive. Open the drive and double-click on the ISO file to mount it. Press "F12" while your computer is launching to enter BIOS mode. There you can choose to boot from the ISO file on your USB Flash drive.

Mount a USB Flash Drive as a Music CD-R

Step 1

Connect your USB Flash Drive to your computer. Choose the MP3 files that you wish to copy and drag them to the drive. Do not put your files in a separate folder unless you know your stereo supports folders.

Step 2

Eject the USB drive and connect it to a stereo's USB jack. Turn the stereo on and select its MP3 mode. Use the "Play" and "Seek" keys to switch between files.

Step 3

Press the "Stop" button on your stereo before you remove the USB Flash drive.

Tips & Warnings

  • Some stereos will allow you to use a USB drive that has multiple folders and file types. Check your owner's manual for additional information.
  • Do not unplug a USB drive if you used it to boot your computer. Shut down the computer and then reboot it normally and eject the USB key.
