TL;DR: To install Ubuntu on Windows 11 dual boot, create a USB installer, disable Fast Startup and Secure Boot, shrink your Windows partition via Disk Management, and complete the installation using the “Install alongside Windows Boot Manager” option.
Installing Ubuntu Linux alongside Windows 11 allows you to choose your operating system at startup, offering the best of both worlds. This process requires careful preparation to ensure your data remains safe and the system boots correctly.
Prepare Your System
Before making any changes, back up your important files. While the installation is generally safe, partition errors can lead to data loss. Next, download the latest Ubuntu ISO file from the official website. You will also need a USB drive with at least 8GB of storage and a tool like Rufus to create a bootable USB drive. Select the ISO file in Rufus, choose your USB device, and click “Start” to write the image.

Restart your computer and enter the BIOS/UEFI settings, usually by pressing F2, Del, or F12 during boot. Locate the “Secure Boot” option and disable it, as Ubuntu may require this for driver compatibility. Save changes and exit. Once back in Windows, search for “Create and format hard disk partitions” to open Disk Management. Right-click your main Windows partition (usually C:) and select “Shrink Volume.” Enter the amount of space to shrink (e.g., 50000 MB for 50GB) and click “Shrink.” This creates unallocated space for Ubuntu. Additionally, open PowerShell as administrator and run `powercfg /h off` to disable hibernation, which can interfere with dual-booting.
Install Ubuntu
Insert the bootable USB drive and restart your computer. Access the boot menu again and select the USB drive. Choose “Try or Install Ubuntu.” When prompted, select “Install Ubuntu” and choose your language and keyboard layout. For installation type, select “Install Ubuntu alongside Windows Boot Manager.” This is the safest option as it automatically uses the unallocated space you created. Avoid “Erase disk and install Ubuntu” unless you want to remove Windows entirely.
Follow the on-screen prompts to set up your user account, time zone, and hostname. The installation will take some time. Once finished, remove the USB drive and click “Restart Now.” You should now see a GRUB menu allowing you to choose between Ubuntu and Windows 11 at every startup.
Pro Tips
Ensure your Windows drivers are updated before starting. If the GRUB menu does not appear, you may need to adjust boot order in BIOS or use a tool like Boot-Repair from a live Ubuntu session.
