Install Ubuntu Over Network from Windows: A Comprehensive Guide

Introduction

Installing Ubuntu over a network from Windows offers numerous advantages, including remote deployment, unattended installations, and efficient resource utilization. This guide provides a step-by-step walkthrough for network-based Ubuntu installations, empowering you to streamline your OS deployment processes.

Requirements

• Windows PC with network connectivity
• Ubuntu ISO image
• Network server (DHCP, TFTP, and NFS services enabled)
• PXE-enabled client system

Step-by-Step Installation

1. Configure Network Services:

• Enable DHCP, TFTP, and NFS services on your network server.
• Configure DHCP to provide PXE boot options and IP addresses to client systems.
• Create an NFS share to host the Ubuntu ISO image.

2. Prepare PXE Boot Server:

• Install the tftpd-hpa package on your network server.
• Copy the Ubuntu ISO image to the TFTP root directory.
• Configure the pxelinux.cfg/default configuration file to boot from the ISO image.

3. Set Up NFS Share:

• Create an NFS share and share the directory containing the Ubuntu ISO image.
• Export the share and grant permissions to client systems.

4. Configure Client System:

• Enable PXE booting in your client system's BIOS settings.
• Set the first boot device to the network interface.

5. Initiate Network Install:

• Start the client system and boot into PXE mode.
• Select the "Install Ubuntu" option from the PXE boot menu.
• The Ubuntu installer will load via the network.

6. Complete Installation:

• Follow the installation wizard to configure Ubuntu according to your preferences.
• Once the installation is complete, reboot your system.

Advantages of Network Installation

• Remote deployment: Install Ubuntu on multiple systems without physically accessing them.
• Unattended installations: Automate the installation process, saving time and effort.
• Efficient resource utilization: Share resources (ISO image, packages, etc.) across client systems.
• Centralized management: Manage all Ubuntu installations from a single server, reducing complexity.
• Security enhancements: Network-based installations can provide enhanced security measures by isolating the installation process from potential local threats.

Common Mistakes to Avoid

• Incorrect network configuration: Ensure that network services are properly configured and accessible by client systems.
• Inaccessible ISO image: Verify that the Ubuntu ISO image is accessible via TFTP or NFS.
• Improper PXE boot setup: Ensure that PXE booting is enabled and configured correctly in your client system's BIOS.
• Insufficient NFS permissions: Grant appropriate permissions to client systems to access the NFS share containing the ISO image.
