Do you need to Dual Boot your PC with Ubuntu and a legacy Windows OS?

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

Note: If you install an operating system (OS) other than the OS that shipped with your system, then you do so at your own risk. Dell cannot certify that the hardware will be compatible. We cannot support the system 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 PC, or you will install windows first before installing Ubuntu.

It is recommended 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 will deal with legacy Windows Operating Systems such as Vista and 7.

If you want to install a recent Windows Operating System such as Windows 8 or 10, please use the article that is linked below:

• How to Install Ubuntu and Windows 8 or 10 as a Dual Boot on your Dell PC

Have you checked that your system type is one of those certified by Canonical as being approved for Ubuntu?

1. If not, then please go to the Canonical site 

   
    and check if your model has been tested by Canonical.

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

Note: If your system did not ship with Ubuntu and you have an issue that requires Technical support Assistance. You may be asked to return the system 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.

Things to know and check before you start an install

There are three things you need to check before you start an Ubuntu Install:

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

What type of Hard Ware are you installing to and will 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 PC. That can be anything from installing on one of the new M2 cards. Installing on a standard SATA hard disk drive. Installing on the same SATA hard disk drives in an Intel Matrix RAID configuration. Check that the hardware of your PC will allow you to make the kind of install you need. Or you can read through the articles that are linked below. These will give you an idea of how to change your installation method to accommodate your system hardware:

• Installing Ubuntu on Systems using PCIe M2 Card Drives on your Dell PC
• Installing Ubuntu on a Dell OptiPlex PC with RAID

Note: Be aware that USB 2.0 and older removable media devices are not supported on systems using the new Intel SkyLake Processors. The Chipsets for the CPUs no longer support the USB 2.0 Hub.

 

What type of BIOS is set up on your system and will it change how you go about your install?

The difference between Legacy and UEFI (Unified Extensible Firmware Interface) BIOS setups can be the difference between an install succeeding or failing. A Legacy Windows OS will usually install on a Legacy BIOS, while a recent Windows OS will need to install on a UEFI BIOS.

• Updating the Dell BIOS in Ubuntu Environments

Which version of Ubuntu are you looking to install?

Ubuntu as with any other operating system is constantly looking to improve and better it is 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 LTS (Long-Term Support) release.

This update is available every two years and is fully supported by Canonical 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 is only supported by Canonical with updates for 9 months. These normal releases are considered to be cutting edge but can have issues because of this. These builds are used by testers and developers.

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

Windows needs to be the First Boot on the Hard Drive

Windows needs to be installed.

If Windows is not already installed? Then go to one of the guides on the link below and select the correct install guide for the Operating System (OS) you will be using:

• An online guide to reinstalling/restoring your Operating System on your Dell PC.

Note: Remember that while setting up your boot partition in the Windows Setup, you can partition the Hard Drive to leave space for the Ubuntu install later on. This will save you a lot of time and effort later on. Remember anytime you work on any operating system, it is best practice to have completed a recent backup in case anything goes wrong.

 

Windows is already installed.

Most PCs come with a version of Windows already installed, and it will take up the whole hard-drive. The Windows partition needs to be shrunk. This will free space for the Ubuntu partition.

Setting up the Install Partitions

1. It is best to do this step from within the windows OS.

For Windows Vista and 7 - Legacy operating systems, you would use Disk Management:

1. Click the Start Button at the corner of your Taskbar and Right-click on My Computer and select Computer Management and go to Disk Management.

   Press the Win+X keyboard shortcut and select Disk Management from the menu that appears.

2. Use the Windows Partition Manager to shrink the partitions.

Note: Do not try and create a partition for Linux here. The Ubuntu Install will deal with this.

 

Note: If you have resized the windows boot partition and cannot boot up windows, then you can use the Windows Recovery tools to fix it. See here for guides on this.

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

Installing Ubuntu as the Second Operating System

1. Have you got a copy of the latest DVD or USB installation media from Canonical? These will include the latest updates and fixes for this operating system.

   .

2. Tap rapidly on the F12 key at the Dell splash screen on startup. It will bring up and Boot Once menu. Using the Cursor/Arrow Keys, select your method of boot and press the ENTER key.

2. In the setup, choose to install the OS to either:

   1. The largest available free space

      1. Marked as Resize IDE1 master, partition #1 (hda1) and use freed space.

      2. Choose the size of the new partition as a percentage of the Hard Drive and click Forward.

      3. Continue with the Install.

   2. Select a partition that you have already created for Ubuntu.

Configuring the Boot Order

1. GRUB2 is the default Ubuntu boot manager. This gives you two choices:

   1. Ubuntu is independent, and this means you do not have to write to other operating systems. You do need to change a line of code in the Master Boot Record (MBR) of the Hard Drive. Which is booted by the BIOS.

      1. The MBR code needs to be changed to point to the Ubuntu boot loader.

      2. Once this is done, you will see a list of operating systems when the PC starts and you can choose which one to boot. It will default boot to Ubuntu after a ten-second countdown.

      3. If you select Windows, then it will load Windows for you at the Windows boot sector. Which is the first sector of the Windows partition.

      4. If it goes wrong, you can run a repair from the install CD.

   2. Do you have a problem changing the MBR code? You can install the code for pointing to GRUB to the first sector of your Ubuntu partition instead.

      1. If you do that during the install process, buntu does not boot, until you change windows boot manager to point to Ubuntu's boot sector.

      2. Windows Vista and 7 no longer utilize boot.ini, ntdetect.com, and ntldr when booting. Instead, they ship with a command-line utility called bcdedit.exe. You can find more information from the Microsoft 

          pages.

• Creating multiple custom partitions during the Ubuntu Install

Note: There are third-party programs that accomplish the same things and might have an easier interface, but you use them at your own risk.

1. Ubuntu is now installed.

2. 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.
