Sometimes the fastest way to recover from a badly misconfigured server, or to start a project on a genuinely clean base, is reinstalling the OS entirely rather than trying to undo every change by hand.
Before you reinstall — this is destructive
An OS reinstall wipes the entire virtual disk and replaces it with a fresh OS template. Every file, database, and configuration on the VPS is permanently erased. Back up anything you need first — either via a snapshot taken before you start (see our snapshot guide), or by copying files/database dumps off the server entirely, since a snapshot taken on the same disk you’re about to wipe may not survive the process depending on how your provider’s snapshot storage works.
Reinstalling in Virtualizor
- In Manage VPS, select the VM.
- Find the OS Reinstall option.
- Choose the new OS template (it doesn’t have to be the same OS/version you had before).
- Set a new root password or SSH key.
- Confirm — Virtualizor will typically show an explicit warning here since the action is irreversible.
What happens next
The VM is rebuilt from the template, usually within a few minutes. Its IP address and Virtualizor-level resource allocation (RAM, disk, CPU) stay the same — only the disk contents and OS change. You’ll need to redo any OS-level configuration (control panel install, firewall rules, SSH hardening) from scratch, exactly as if this were a brand-new VPS.
When reinstalling makes sense
- The server has accumulated so much conflicting/broken configuration that fixing it piece by piece would take longer than starting clean.
- You suspect a compromise and want a guaranteed-clean base rather than trying to manually verify nothing malicious remains.
- You’re repurposing a VPS for a completely different project and don’t need any existing data.
For anything less drastic, restoring a recent snapshot or backup is usually faster and less disruptive than a full reinstall.
