Troubleshooting Without Diagnostics Solving CD-ROM and DVD Problems Solving CD-ROM and DVD Problems Problem Cause System will not boot from CD-ROM or DVD drive.

Network Server Mode is enabled in Computer Setup. Non-bootable CD in drive. Boot order not correct. Drive not found (identified). Cable could be loose.
