Why each option

The server rebooted mid-installation and restarted from the DVD because the BIOS boot order prioritizes the optical drive over the hard disk.

ATry installation again with a different DVD.

The installation started successfully from the original DVD, indicating the disc is readable and not defective - swapping it does not address the boot order issue.

BModify the device boot order in the BIOS.Correct

OS installations require one or more reboots to continue setup from files copied to the hard drive. If the BIOS boot order lists DVD before HDD, each reboot causes the system to boot from the DVD again and restart the installation from the beginning. Changing the boot order in BIOS to prioritize the HDD after the initial boot allows the installation to proceed correctly through all phases.

CMonitor the operating system installation process completely this time.

Monitoring the process does not change the BIOS boot order, so the server will continue rebooting back to the DVD regardless of observation.

DSwap the hard drive with a known working one.

The hard drive is not shown to be faulty - the symptom is a boot order misconfiguration, not a storage hardware failure.
