How to Dual Boot Lubuntu and Windows

Install Linux Lubuntu on your Windows 10 PC

Want to dual boot Windows and Linux on the same PC? Here's how to install Lubuntu alongside Windows so that you can switch between both operating systems.

These instructions are for installing Lubuntu 18.01 on a PC running Windows 10, 8.1, or 8.

Prepare Your PC for Lubuntu

After doing everything necessary to prepare your PC for dual booting Linux and Windows, you should create a Windows recovery partition with Macrium Reflect or another software backup tool in case something goes wrong. Make sure you have enough free space on your hard drive for Lubuntu and any Linux programs you want to run (at least 10GB).

After creating a bootable Lubuntu USB drive, plug it into your computer and boot from the USB device. You can try out Lubuntu right away, but any changes you make won't be saved until you install it on your hard drive.

When your PC reboots, you should have the option to boot Windows or Lubuntu (although it might be called Ubuntu). Restart your computer whenever you want to switch operating systems.

If your computer automatically boots into Windows, you need to change the boot order using EFI Boot Manager, which comes with the live version of Lubuntu.

Because Lubuntu is a lightweight version of Ubuntu, the default desktop is very bare bones; however, there are number of ways to improve the Lubuntu interface to make it more functional.
