Proxmox VE Install os in dedicated server

I need Proxmox VE freshly installed and fully configured on a dedicated server that is currently running an OS other than Ubuntu, CentOS, or Windows Server. After the base installation, I want the node prepared for a high-availability environment—corosync set up, quorum verified, fencing method agreed and tested, and the storage layout ready for additional nodes to join later.

Please handle:

• Bootable Proxmox installation (latest stable release)
• Proper networking: bridge configuration and access to the web console
• HA configuration with clear documentation of every step you take

The job is finished once I can reach the Proxmox dashboard, see the HA tab functional without errors, and have a short set of notes outlining the commands or settings you applied so I can replicate them on future nodes.
