In this article, we’ll guide you through the process of setting up a dual boot system with Ubuntu and Windows 8 in UEFI mode. This can be a complex process, so we’ll break it down into manageable steps.
To dual boot Ubuntu and Windows 8 in UEFI mode, you need to disable Secure Boot, partition your hard drive, install Ubuntu, and fix any boot issues with the Boot Repair tool. It is a complex process that requires careful preparation, but following the steps outlined in this article will help you successfully set up a dual boot system.
Before you start, ensure you have a backup of your important data. This process involves partitioning your hard drive, which can lead to data loss if not done correctly.
You’ll also need a bootable USB or DVD of Ubuntu. You can download the latest version of Ubuntu from the official website and use a tool like Rufus to create a bootable USB.
Step 1: Disable Secure Boot
UEFI mode often comes with a feature called Secure Boot, which prevents booting from unauthorized sources. To dual boot Ubuntu, you’ll need to disable this feature.
To disable Secure Boot, restart your computer and enter the BIOS setup. This is usually done by pressing a specific key (such as F2, F10, or Del) during startup. Once in the BIOS setup, look for the Secure Boot option and disable it. Save your changes and exit.
Step 2: Partition the Hard Drive
Next, you need to create space on your hard drive for Ubuntu. This can be done from within Windows 8.
- Open the Disk Management tool by pressing
Win + Xand selecting Disk Management.
- Right-click on the main partition and select
- Enter the amount of space you want to allocate to Ubuntu (at least 20GB is recommended) and click
This will create an unallocated space on your hard drive where Ubuntu will be installed.
Step 3: Install Ubuntu
Now you’re ready to install Ubuntu.
- Insert your bootable Ubuntu USB or DVD and restart your computer.
- During startup, press the appropriate key to open the boot menu and select your bootable Ubuntu media.
- Once the Ubuntu installer loads, select
- When asked about installation type, select
- In the partitioning screen, select the unallocated space you created earlier and click
- Create a root partition by selecting
Ext4 journaling file system, setting the mount point to
/, and clicking
- If you have more than 2GB of RAM, you can also create a swap partition. This should be roughly equal to your RAM size.
- After creating the partitions, click
Install Nowto start the installation.
Step 4: Fix Boot Issues with Boot Repair
Sometimes, after installing Ubuntu, the system might boot directly to Ubuntu, bypassing the GRUB bootloader that allows you to choose between Ubuntu and Windows 8.
To fix this, you can use the Boot Repair tool.
- Open a Terminal in Ubuntu by pressing
Ctrl + Alt + T.
- Add the Boot Repair repository with the command:
sudo add-apt-repository ppa:yannubuntu/boot-repair
- Update your system with the command:
sudo apt-get update
- Install Boot Repair with the command:
sudo apt-get install boot-repair
- Run Boot Repair with the command:
Follow the prompts to complete the repair process. This should fix any issues with the bootloader and allow you to choose between Ubuntu and Windows 8 at startup.
Setting up a dual boot system with Ubuntu and Windows 8 in UEFI mode can be a complex process, but with careful preparation and following these steps, you should be able to get it done successfully. Always remember to back up your data before making any major changes to your system.
Yes, you can dual boot Ubuntu and Windows 8 in UEFI mode without losing your data. However, it is always recommended to back up your important data before proceeding with any partitioning or installation process.
It is recommended to allocate at least 20GB of space for Ubuntu. However, you can allocate more if you have the available space on your hard drive.
Yes, you can enable Secure Boot after installing Ubuntu. However, it is important to note that enabling Secure Boot may prevent certain unauthorized operating systems or bootloaders from running. Make sure to research and understand the implications before enabling Secure Boot.
Having a swap partition in Ubuntu is recommended, especially if you have more than 2GB of RAM. The swap partition acts as virtual memory and can be useful when your system runs out of RAM.
To access the BIOS setup, restart your computer and press a specific key (such as F2, F10, or Del) during startup. The specific key may vary depending on your computer’s manufacturer. Once in the BIOS setup, look for the Secure Boot option and disable it. Save your changes and exit.
If the GRUB bootloader doesn’t appear after installing Ubuntu, you can use the Boot Repair tool to fix the issue. Follow the steps mentioned in Step 4 of the guide to use Boot Repair and restore the bootloader.
Yes, you can dual boot Ubuntu with Windows 8 in Legacy BIOS mode. The steps and requirements may be slightly different, so it is important to follow a guide specifically tailored for Legacy BIOS mode dual booting.
