While a disconnected network cable could cause a PXE boot failure, the primary issue is the boot order attempting PXE boot in the first place when it should be booting locally; correcting the BIOS is a more fundamental first step than just checking the cable.

An optical disk in the CD-ROM drive might cause boot issues if it's bootable and higher in the boot order, but it wouldn't specifically result in a "PXE server not found" error message, which points directly to network boot attempts.

The message "PXE server not found" indicates that the server is attempting to boot from the network (PXE - Preboot eXecution Environment) as part of its boot order and cannot find a PXE server. The technician should enter the BIOS/UEFI settings and modify the boot sequence to prioritize booting from an internal hard drive or other local media where the operating system resides, which is the most common and likely issue.

Reseating PCI cards is a hardware troubleshooting step typically performed when there are system stability issues, hardware detection problems, or no boot at all, but it is not directly related to a "PXE server not found" message which points to a boot order misconfiguration.
