As usual with Ubuntu, every fourth month after two years, we have the new release which is now Ubuntu 18.04 code named Bionic Beaver. It is a new Long Term Support (LTS) release which offers 5 years of support for both desktop and server versions. You can install this new system on your computer even if you have an existing Windows system. This article will show you step by step how you can install Ubuntu 18.04 in dual boot with Windows 10, so it assumes that you have an existing Windows 10 EFI.
What's new on Ubuntu 18.04
The final release of Ubuntu 18.04 can be downloaded from official Desktop and Server Iso images. However, you will not find 32-bit ISOs available because Ubuntu dropped 32-bit desktop builds during the 17.10 development cycle. The new LTS can be used on production and contains some new features:
- Gnome 3.28 : Ubuntu 17.10 was the first release to offer gnome instead of unity and now Ubuntu 18.04 will keep the same trend and will feature the latest GNOME.
- Kernel 4.15 : Ubuntu 18.04 will use the version 4.15 of the kernel, the latest stable release instead of 4.14 which was originally planned by canonical.
- Color emoji : The previous version of Ubuntu only supported monochrome emojis but the new Ubuntu will support colored emojis
- Suru the new icon theme : Ubuntu 18.04 will use a new icon theme Suru which will be the new default icon theme.
- Minimal installation option : The new LTS offers a new option in the installation process that allows you to perform a minimal installation of Ubuntu which removes around 80 packages from the default installation (Thunderbird, LibreOffice, etc)
- Xorg : Xorg will be used by default as the graphic server instead of Wayland for its compatibility with services like Skype, WebRTC, RDP, and more. The new LTS release will ship with both Xorg graphics and Wayland-based stack.
- Faster boot time : The boot time has been improved on Ubuntu 18.04. by using systemd’s features.
- Collect data : Ubuntu 18.04 will automatically compile data about your system and send it back to help improve Ubuntu.
- New installer for Ubuntu 18.04 Server edition : the new server edition of Ubuntu 18.04 will use the new subiquity installer.
- Kernel Updates : More easier to install kernel updates without rebooting
1) Check EFI or Bios mode on Windows 10
It exists two firmware interfaces for computers which are BIOS and EFI that work as an interpreter between the operating system and the computer firmware. The dual boot is the coexistence of two different operating systems on the same physical machine. In our case, We will try to install Ubuntu 18.04 alongside your Windows 10 so we must check the installed mode:
- BIOS boots by reading the first sector on a hard disk and executing it; this boot sector in turn locates and runs additional code. The BIOS system uses the Master Boot Record (MBR) partition table which is very limiting because of space (no more than 2TB in size per partition) and partitions (more than 4 primary partitions) constraints.
- EFI boots by loading EFI program files (with .efi filename extensions) from a partition on the hard disk uses the GUID partition table (GPT) offering 64-bit entries in its table which dramatically extends the support for size possibilities.
If your Windows is installed in Bios mode, it is recommended to install your Ubuntu in Bios mode but if it's installed in EFI, so do the same with Ubuntu. To Check if your Windows is installed in EFI, use the combination
windows + r then enter the command
msinfo32 as below
then you have a new windows where the mention Bios Mode gives the indication
2) Configure Windows for dualboot
Now we need to do some operations in the Windows system in order to install our Ubuntu 18.04
a) Check the partitions
Now that you have checked that you have an EFI mode, we need to check the disk or the partitions to use for Ubuntu. So that we will open the disk management with the combination
windows + r then enter the command
now you can check the GUID partition table (GPT). You can see the disks and partitions. In my case, I have one disk and I will install Ubuntu in a partition. To look the partition table, do a right click on the disk and choose the properties
Then go the Volume tab. You can see that you use GPT
I will install Ubuntu in the partition of 20Go and to avoid any mistake with the partitions of windows during the process, I will delete the partition to use here.
You can see that it is now unallocated
b) Disable fast startup and secure boot
The fast startup ( known as fast boot on Win 8) can prevent to boot on the Ubuntu CD so you can need to disable it. Use the combination
windows + x and choose the power management
In the Power Options window, click Choose what the power buttons do.
you’ll need click Change settings that are currently unavailable to make the Fast Startup option available in order to edit it.
Now uncheck it
The secure boot can prevent the grub to boot your system properly so we will disable it. Open the setting and choose the windows update option
Now restart in the advanced startup
now choose the troubleshoot option
Now restart. Your system will restart and will give you the opportunity to disable secure boot
3) Install Ubuntu 18.04
a) Boot from Ubuntu EFI mode
Because our Windows is installed in EFI mode, we need to install Ubuntu 18.04 in EFI too. Normally, after disabling the secure boot, you can boot from you Ubuntu 18.04 installation CD. You will have the black screen which indicates that Ubuntu boot from EFI
If you are not able to boot from your installation media, don't worry. Boot from Windows and use the steps to restart in advanced startup but you will change one option. Instead of Troubleshoot, you will choose the option use a Device which will automatically detect all the EFI media. Then you will choose the appropriate EFI installation media
b) Prepare the disk
To be sure to make no mistake, we must identify the disks or partitions on which we will install our Ubuntu. So will boot Ubuntu with the option try Ubuntu without installing
The system will boot in live mode
We will use gparted tool to create the partition
We will create two partitions on Ubuntu 18.04:
- root: it will store everything related to the system
- home: it will store the personal data of the different accounts related to your Ubuntu system
We don't need to create the swap unless you have limited resources. Now it's possible to create swap file which means don't need a complete partition.
We will create the partitions here to avoid any mistakes during the installation process. We create the root partition
Do the same with the home
you can check if it is correct, then apply
c) Launch the installation
Now go to the desktop in order to launch the installation by clicking on the shortcut that you see. First, choose the language
Then choose your keyboard
Because we do a complete installation, we will not choose the minimal installation
Now choose the type of the installation. For a manual installtion, we will choose the last option
Now we can see all the partition but the type (filesystem) help us to know directly which partitions to use. You can see an EFI partition which is present, it is the windows boot partition. Normally, for a single installation of Ubuntu, you need to create an EFI boot partition which will be used but as it's present because of Windows already installed, no need to create a new one.
Now you can choose the mount point and the filesystem as below
now do the same with the home
Edit the partition and choose the mount point
now that you have finished, you can choose install
You will receive a warning to tell you all the data will be deleted
Now you can configure your exact location. By specifying your exact location, you will allow Ubuntu to communicate with the nearest repositories for installation and package updates.
Now you can create the user account with a solid password
Now you can proceed with the installation of your filesystem and the updates during the process
When the process will finish, you will receive a message that will ask you to restart the computer and then to remove the installation media
Now when restarting, you can see the grub which gives you the possibility to choose the system to launch
If you don't see the grub when you restart, don't worry. In some other cases, you need to press the boot options key which is generally F9. Then you will see the different systems installed and you can choose the one to use. Now your system will boot and you will need to log in with the password created during the process
You can see the new system
You can launch the Ubuntu software to install some new packages
You can navigate in your new Ubuntu 18.04 system. To see the different partitions or disks, go to Other locations
Now have your system installed and ready to be used.
d) Fix grub is windows 10 entry is not present.
For some reasons your system can directly boot on Ubuntu 18.04. You need first to make sure that the grub appears with the different OS entries. If not, check first the
/etc/default/grub file to see if the grub-menu is activated at boot time. Find the line
GRUB_HIDDEN_TIMEOUT=0 and edit it by changing the value 0 to another such as 20.
If the grub appears but not your Windows 10, it means that information about the Windows EFI boot partition is not found. So, you will need to complete some additional steps. After booting on your Ubuntu 18.04, you can use one of the options below:
- update-grub command: It will rebuild your
/boot/grub/grub.cfgfile with the menu entries.
- boot-repair: it is a simple tool to repair frequent boot issues you may encounter in Ubuntu dualboot when you can't boot Ubuntu or Windows or another Linux distribution. You will need to install it
# add-apt-repository ppa:yannubuntu/boot-repair # apt update # apt install -y boot-repair && boot-repair
Now you can launch boot-repair with the recommended option
- manually add windows entry: This solution provides a proper entry in the grub2 menu to boot into Windows 10. First check on which disk and partition is the Windows EFI boot
# fdisk -l
Now found the UUID of the partition
# blkid /dev/sda2 /dev/sda2: UUID="1AC3-9984" TYPE="vfat" PARTLABEL="EFI system partition" PARTUUID="dda518e7-aa6d-4944-9a59-e459f0f7944e"
Then you can edit the
/etc/grub.d/40_custom grub file to add the lines which will help you to boot into your Windows system
# vim /etc/grub.d/40_custom menuentry 'Windows 10 (on /dev/sda2)' --class windows --class os $menuentry_id_option 'osprober-efi-1AC$ insmod part_gpt insmod ntfs insmod search_fs_uuid insmod chain set root='hd0,gpt2' if [ x$feature_platform_search_hint = xy ]; then search --no-floppy --fs-uuid --set=root --hint-bios=hd0,gpt2 --hint-efi=hd0,gpt2 --hint-barem$ else search --no-floppy --fs-uuid --set=root 1AC3-9984 fi chainloader /EFI/Microsoft/Boot/bootmgfw.efi }
note that entry is configured to boot from the 2nd partition
gpt2 of the 1st hard drive
ahci0. If you are working on legacy, then replace all
Now you can update the grub file
Restart you system to see the grub
Now you can boot normally on Windows 10
