# VPS Re-install Debian Script

Now ready for Debian 10 (buster)!

## Introduction

This script is used to re-install VPS to **Debian 9 (stretch) or 10 (buster)** with the official installer, but semi-automatically.

## How It Works

1. Generate a preseed file to automate installation
2. Download Debian Installer to the boot directory
3. Alter GRUB2 configuration to boot the installer
