Final answer:
To perform an OS installation on a headless system remotely, utilize Out-of-Band management technologies like Intel AMT or Dell iDRAC, or employ a network-based installation method such as PXE booting, assuming you have the required network access and permissions.
Step-by-step explanation:
If you need to perform an OS installation on a headless system that you have no physical access to, you'll have to rely on remote management solutions. First, check if the system has any Out-of-Band (OOB) management technologies like Intel AMT, Dell iDRAC, HP iLO, or similar. These technologies allow you to control the system as if you were physically present, including mounting virtual media to perform an installation.
If OOB is not available, you could use a network-based installation method such as PXE booting. This would necessitate configuring a server on the network to serve the OS installation files and then directing the remote system to boot from the network.
Both solutions assume you have network access and the necessary permissions to manage the device remotely. It's always critical to ensure the system's BIOS or UEFI settings are configured to support these remote installation methods.
