You want to Dual Boot your computer with Ubuntu and a Windows operating system?

This guide takes you through how to set up your computer to dual-boot Ubuntu and Windows.

NOTE: If you install an operating system other than the one that shipped with your computer, then you do so at your own risk. Dell cannot certify that the hardware is compatible and we cannot support the computer in that configuration. This article is provided as information for those customers who want to dual-boot, but it is carried out at your own risk.

Where Windows is already installed on your computer, or you install windows first before installing Ubuntu.

It is recommended that a Windows operating system should be installed first. Windows does not include Non-Microsoft operating systems in its boot-menu. Installing windows can also affect any information already on your Hard Drive.

This article deals with recent Windows Operating Systems such as Windows 8, Windows 8.1, Windows 10, and Windows 11.

Have you checked that your computer type is one of those Canonical certified for Ubuntu?

  • If not, then go to the Canonical site This hyperlink is taking you to a website outside of Dell Technologies. and confirm that Canonical and Dell supports your model for Ubuntu.

  • If you have and it is supported on this list, then carry on.

NOTE: If your computer did not ship with Ubuntu, and you have an issue that requires Technical Support Assistance to resolve. You may be asked to return the computer to the condition it shipped from Dell and advise if the issue continues at that point. If it does not, then there would be limited support possible at that point. This guide talks about Windows 8, through to 11 alongside Ubuntu 16.04 to current.

Things to know and check before you start an install

There are three things that you must consider before you start an Ubuntu Install:

  1. To check the type of hardware that you are trying to install to?
  2. To check the type of BIOS settings that you need for your install?
  3. To check what version of Ubuntu that you are looking to install?

What type of Hardware are you installing to and does it change how you go about your install?

The type or format of your storage media can affect how you would go about installing Ubuntu on your computer. You can install on one of the new M2 cards. You can install on a standard SATA hard disk drive. You can install on the same SATA hard disk drives set in an Intel Matrix RAID configuration. Check that the computers hardware allows you to make the install you need. Alternatively, read through the articles that are linked below to get an idea of how to change your installation method to accommodate your computer hardware:

NOTE: USB 2.0 and older removable media devices are not supported on computers using the new Intel SkyLake Processors. The Chipsets for the CPUs no longer support the USB 2.0 Hub.

What BIOS settings do you need for your UEFI install?

NOTE: Be Aware the latest generation of Dell computers has dropped Legacy support from their BIOS.

The difference between Legacy and Unified Extensible Firmware Interface (UEFI) BIOS setups can be the difference between an install succeeding or failing. Follow the information below:

Press the F2 key on start up to enter the BIOS. Ensure that the BIOS is set to UEFI, and disable the Legacy option ROMS and disable the secure boot.




NOTE: Not every Dell BIOS has the same appearance and the page names may change depending on the model type. However, these general instructions work on any Dell BIOS that supports an Ubuntu install.

Which version of Ubuntu are you looking to install?

Ubuntu as with any other operating system is constantly looking to improve and better its usage and performance. What is different with Ubuntu is that you have the option of two updates at any time:

The first is the most recent Long-Term Support (LTS) release.

This update is available every two years and Canonical supports it with updates for five years. It is considered a tested and stable build.

The second is the most recent Normal release.

This update is available every 6 months and Canonical supports updates for 9 months. These normal releases are considered to be cutting-edge but can have issues because of this. Testers and developers use this type of build.

If you are looking instead to upgrade to a new version of Ubuntu, then check out the article that is linked below:

NOTE: There have been reports that certain Windows setups using the Rapid Storage Technology (RST) driver, can cause issues during the install. You can find out more from Canonical on the following link:

Windows must be the First Boot on the Hard Drive

Windows must be installed first.

Where Windows is not already installed, use one of these guides on the link below. It shows the correct install guide for the Operating System that you are using:

NOTE: Remember: While setting up your boot partition in the Windows Setup, partition the Hard Drive to leave space for the Ubuntu install later on. This saves you a lot of time and effort later on. Remember whenever you work on your operating system it is best practice to have a recent backup, in case something goes wrong.

Windows is already installed.

Most computers come with a version of Windows that is already installed and it takes up the whole hard drive. The Windows partition must be shrunk. This frees space for the Ubuntu partition.

  1. Once you have sufficient Unallocated Space on the Hard Drive, then it is straightforward to install Ubuntu as the second operating system. You want to boot from your Ubuntu DVD or USB drive.

  2. Ensure you are logged in as an Administrator and check if Fast Startup is disabled. (This can affect whether GRUB can pick up your Windows installation at a later stage.)

    1. Open the Control Panel. (The windows key + X is a shortcut on all recent versions.)

    2. Open the Power Options.

    3. Select Choose what the power button does.

    4. Select Change settings that are currently unavailable.

Configuring the Boot Order

The computer reboots into the GRUB menu and sits for 10 seconds while you choose which Operating System you want to boot with. Ubuntu 16.04 to current, or Windows 8 to 11.

Ubuntu is set as the default operating system to boot to. That means if you press the Enter key or wait out the 10 seconds, it boots straight to Ubuntu.

Once Ubuntu finishes loading, login in with the username and password you set. Since version 16.04, Ubuntu has provided NTFS file system support automatically. That means you can access information and files from the Windows partitions by clicking the Windows Volume.

If you want to change to the windows installation, reboot the computer and choose the windows partition from the GRUB menu.

You can go to the guide below for some initial setup information:

NOTE: If you have completed the installation and there are any issues, the easiest and quickest resolution is to run the install again.
