Dual Boot Windows with Ubuntu: A Comprehensive Guide

As technology evolves, having multiple operating systems on a single laptop or PC is increasingly common. This guide will walk you through the process of installing Windows on a laptop that has Ubuntu pre-installed, explaining the requirements and providing step-by-step instructions.

Preparation and Requirements

Before you proceed, it is crucial to understand that the installation of both Windows and Ubuntu will partition your hard drive. Here are the key requirements:

2 GB of RAM: Minimum requirement to accommodate both operating systems. 2 Drives: Each operating system needs a dedicated partition for best performance. If your laptop only has one hard drive, you may need to upgrade or create a second drive. Data Backup: Ensure you have a backup of all important data before proceeding, as partitioning and installation may result in data loss.

Create a Bootable Media
