This post shows you how to install Ubuntu Server from from its Minimal ISO Image. The mini ISO image only contains the bare minimal of bootable software to get you started with installing Ubuntu, and will download only the bare minimal of Ubuntu Server utilities from online archives at installation time.
Most folks prefer to install Ubuntu Server from its minimal ISO image instead of using the full media CD/DVD which may contain packages that you may never use on your servers. So instead of installing a full server image of Ubuntu where you may not need many of the software packages included with it, get the bare minimal image and install only packages you need.
Also, the minimal ISO image (mini.iso) is about 60MB in size, compare to the full server image which may be around 700MB. This allows you to customize your server installation and do it quickly as possible.
To get the mini.iso image for your machine, click the link below
When you get the mini.iso image downloaded, use a functioning computer to burn the image onto a CD/DVD. If you’re installing it on a virtual machine, then just create a guest machine an attach the ISO image and boot from it.
When booted, follow the screenshots below to complete the installation.
On the boot menu, select Install and press the Enter key to begin the installation.
The next screen is where you choose the language to be used for the installation process. If you choose the wrong language, you may not be able to follow through with installation as it may be difficult to read the questions.
On the next screen is where you will choose and set your timezone. Since, I’m in the United States, I selected that.
Next, select No to detect your keyboard layout. It’s always good to manually choose the layout during the installation.
Then choose your keyboard layout and continue.
Next, select the layout matching your previous selection and continue.
On the next screen is where you type the system name or hostname. Type a name for your machine and continue.
On this screen is where you select the archive mirror to download Ubuntu packages from. Always select the archive closest to you for quicker download.
Select the highlighted archive and press Enter to continue.
Then type your full name. maybe just your first name?
Then type a username to use to login to the system. This account will be the administrative account and you’ll need to use your username to authenticate.
Next, type and confirm a password for the account
Then select No if you don’t want to encrypt the account home directory. If you want to encrypt the account home directory, choose Yes to do it.
Then accept the timezone location. If it’s not correct, select No.
Next, select the Guided – Use entire disk for the partitioning method and continue. This is the easiest method.
Next, select the disk to partition and continue.
Then when prompted whether to write the changes to disk, click Yes. If you choose yes, everything on that disk will be erased.
During the installation, when prompted to choose how to upgrade your system, select Install security updates automatically.
Now is where you select the packages to install along with the standard system utilities. All these packages can be install later if you don’t select them from here.
Because this is the only operating system on the computer, you should install GRUB boot loader to the master boot record. Select Yes.
Finally, select continue to reboot the machine after the installation. When you restart, your computer will prompt you for a username and password.
Type your credentials and you should able to login.
