I am new to the Linux community and ended up installing 17.04 a while back ago. However, now I really regret that.

I need to have both Windows 10 and want to upgrade to 18.04 LTS as I hear it's available today. Can you please provide me a step by step guide on doing this? I don't have a great understanding of Linux systems yet, so I would appreciate a guide in layman's terms.

How to install dual boot system Ubuntu and Windows. Quick guide

When installing dual boot system, main question is how to organize disk space for convenience using. This guide is how to do that.

1. Backup your files !! Always do this first !!


2. Boot from Ubuntu bootable CD and run gparted program.


3. Format all your HDD to Primary partition, NTFS, enable checkboxes Active, Bootable. It is necessary for Windows not to format HDD theirs way.


4. Install Windows onto this partition. Don't format it from installation program, otherwise it will make 2 partitions instead of one.


5. Boot from Ubuntu bootable CD and run gparted program.


6. Resize NTFS partition to appropriate capacity. 20 Gb is enough. It may be larger, according to your HDD capacity.


7. Move NTFS partition to the third quarter of HDD.


8. Create new primary partition Swap onto beginning of your HDD. Space = double memory space.


9. 
   

   Create new primary partition ext4 next to Swap partition, enable checkboxes Active, Bootable. 20 Gb is enough. It may be larger, according to your HDD capacity. (It will be / (root) partition on next steps). Windows NTFS partition should go next to this partition.

   
   
   

   note: There should be no free spaces between all this partitions.

   
   


10. 
    

    All free spaces, which remains in fourth quarter of HDD use for new partition ext4. (It will be /home partition on next steps)

    
    
    

    note: There may be only 4 primary partitions on one HDD.

    
    


11. 
    

    Apply changes.

    
    
    

    note: Instead of gparted program you may want to use Acronis Disk Director bootable CD - it works faster.

    
    


12. 
    

    Now it is time to install Ubuntu.

    
    
    

    Q: Why Ubuntu second and Windows first?

    
    
    

    A: If you do vice versa Windows kills Grub and you'll be able to boot only Windows. Ubuntu don't do the same with Windows.

    
    


13. 
    

    When installing Ubuntu, choose:

    
    
    
    • first partition for Swap,
    
    
    • second - for / (root).
    
    
    • third - don't use (you'll be able to mount it from Ubuntu's Nautilus or Gnome Disk Utility),
    
    
    • fourth - for /home.
    
    

    Other settings are up to you.

    
    



14. After installation process ends, remove CD and reboot into Grub. You'll see several rows to choose boot from: Ubuntu and Windows.
