Guide through the process of installing PureOS from live instance

NOTE: This guide assumes that you have booted to live PureOS instance.

Pre-installation steps

  • Start the live PureOS instance from a USB you have prepared.
  • Choose option 1 (Start live PureOS) at the PureOS boot prompt and wait for the GNOME desktop to fully start.
  • Follow the steps below:

Simple installation

  1. Start the Calamares installer:

PureOS live instance 1

  1. Ensure that you are connected to the power supply and the internet, and click Next:

Calamares install 2

  1. Choose your time zone, set the system language and number and date locale:

Calamares install 3

  1. Select your keyboard layout:

Calamares install 4

  1. Disk partitioning. Assumed is that your disk is blank. Choose automatic partitioning (Erase disk option), the installer will automatically partition your disk. Type-in the password you wish to use for the full disk encryption. Leave it out if you do NOT want disk encryption:

Calamares install 5

NOTE: Make sure to select proper device to install to! See the options encircled in red. Ignore if you only have one disk installed.

  1. Create a user:

Calamares install 6

  1. Review install instructions:

Calamares install 7

  1. ...and confirm the installation:

Calamares install 8

  1. Wait for few minutes:

Calamares install 9

  1. And restart after it is done.

Calamares install 10

Advanced installation

Follow steps 1-4 from Simple install.

  1. Select Manual partitioning:

Calamares install 5_adv

5a. First, click New Partition Table to create new partition table:

Calamares install 5a

5b. ...and select GPT (click OK to accept):

Calamares install 5b

5c. Now click on free space and click Create to create first partition:

Calamares install 5c

5d. Since we used GPT partition table, we need to create a partition with special flag. It can be of minimum size, so set the 1 MB size (installer might increase this value to something like 8 MB, ignore this), set File System to unformatted and select bios-grub flag (this is important). Click OK afterwards:

Calamares install 5d

5e. Click on Free Space and then the Create to create next partition:

Calamares install 5e

5f. In this example, swap partition is created next. Swap is needed for proper hibernation, and since the system has 8 GB of RAM, the size here is set to 7168 MB (7 GB). If your system has more RAM, make this partition larger. Choose linuxswap as file system:

Calamares install 5f

5g. Next, create root partition (place where your system is going to be installed). In the example here the size is set to 20 GB. You can set it larger if you plan to install a lot of sotware. Choose ext4 as filesystem, as it is the most stable and most tested. Don't use btrfs on your production builds! Set / for mount point:

Calamares install 5g

5h. Create the home partition. This is the place where your data will reside. Use the rest of disk space. Set /home for mount point:

Calamares install 5h

5i. Review your partitioning:

Calamares install 5i

Follow steps 6-10 from Simple install.
