As someone who tinkers with home lab projects on a daily basis, I’ve seen the Proxmox setup screen so many times that it practically lives rent-free in my head. Failed networking projects, bootloader misadventures, cluster accidents, and incorrectly set-up permissions often end up with me reinstalling Proxmox from scratch. While there are ways to recover from them, starting from a clean slate is the easiest method – especially for nested server VM and experimental home lab devices.
