Problems reading or booting from DVD/CD-ROM media (102)

Details

You are experiencing these issues:
  • Cannot read DVD/CD media.
  • Cannot boot from the DVD/CD-ROM.

Solution

Note: Before proceeding further through this article, ensure that the virtual cd-rom device is connected to the virtual machine and that the "Connect at power on" checkbox is checked.
 
Be sure your virtual machine is configured to boot from CD.
  1. Power on the virtual machine.
  2. When you see the BIOS screen, press the Esc key. The boot device selection menu appears.
  3. From this menu, select the CD-ROM drive as the boot device.

Be sure your installation CD is a bootable CD. Try to boot this CD on a similar host running the same operating system to see if the media you are using is bootable. If it does not boot in your host, it cannot boot in a virtual machine. To work around this problem, boot from a bootable floppy disk with CD-ROM drivers, then run the installation program on the CD.

See if your installation disc is a DVD, multisession CD, CD-R or CD-RW. If so, you may need to configure your virtual CD-ROM drive for raw access. To do so, follow these steps:

Windows

  1. With the virtual machine powered off, open the Configuration Editor (choose Settings > Configuration Editor), and select the DVD/CD-ROM.

  2. Select Enable raw access.

  3. Click OK to save the change and close the Configuration Editor.

  4. Be sure the installation disc is in the drive, then power on the virtual machine.

Linux

Note: In order to use raw access mode for a CD-ROM drive on a Linux host, you must configure the host operating system to use the ide-scsi module. For more information, see Guest Does Not See CD Drive Set for Raw Access on Linux Host (834).

  1. With the virtual machine powered off, open the Configuration Editor (choose Settings>Configuration Editor), and select the DVD/CD-ROM.

  2. Change the Device Type from CD-ROM to CD-ROM (raw access).

  3. Click OK to save the change and close the Configuration Editor.

  4. Be sure the installation disc is in the drive, then power on the virtual machine.

If the previous suggestions do not resolve your problem, try making a CD-ROM image file from the disc and use that.

Note: If the CD-ROM is not bootable, an ISO image of the CD will not be bootable, either.

To use an image file in the virtual machine, follow these steps:

  1. On the host computer, create an ISO image of your installation CD. Save the ISO image file in any location accessible to your host. For best performance, place this image on the host computer's hard drive.

  2. With the virtual machine powered off, open the Configuration Editor (choose Settings > Configuration Editor), and select the virtual CD-ROM device.

  3. On Linux host machines, change the Device Type to CD-ROM image and enter the path and filename of the ISO image.

    On Windows host machines, select Use ISO image, then browse to the image file and select it.

  4. Power on the virtual machine.

Creating an ISO Image File on Windows

Many CD-ROM creation programs, such as Easy CD Creator and Nero Burning ROM, also allow you to create ISO image files. See the documentation for your CD creation software for details on how to create the image file.

Creating an ISO Image File on Linux

On a Linux host, you can use the dd command to create an ISO image file. To do so, insert the CD into your CD drive, then enter the following command:
dd if=/dev/cdrom of=cd.iso

If your CD drive has a different device name, substitute the correct device name for /dev/cdrom. Substitute a path and filename of your choice for cd.iso.
