====== Installation ====== | ====== Installation ====== | ||
+ | |||
+ | Boot your USB stick, you should be prompted by a small menu, select " | ||
+ | |||
+ | Be aware the following is for openSUSE MicroOS, the steps for other openSUSE editions are very similar but classic editions prompt for disk setup earlier than we do it in this guide, just scroll down to see what you should do, everything is explained here, just not in the right order for classic editions. | ||
+ | |||
+ | {{: | ||
+ | |||
+ | Now wait till the installer loads. It may take some time, especially if your USB stick is slow, so grab a coffee ☕️. | ||
+ | |||
+ | Once the installer has started, you will be welcomed by a Language and Keyboard selection page. Set up your language and keyboard layout then click next. | ||
+ | |||
+ | {{: | ||
+ | |||
+ | Next, you will be prompted to choose a System Role. This is basically what you want to do with your openSUSE installation. You should choose either GNOME or KDE Plasma when using MicroOS. If you use openSUSE Tumbleweed, you can choose Xfce here, which isn't available in other editions. It is much lighter. On the screenshot, I chose GNOME. As of time of writing, both are still experimental in MicroOS, but I had no issues so far with both. | ||
+ | |||
+ | {{: | ||
+ | |||
+ | Next, the installer will prompt you to create a new user, choose whatever you want for your full name, but the username should be kept simple (no caps, no spaces, no special characters, i'd recommend you limit to a-z and 0-9). | ||
+ | |||
+ | Preferably, setup a strong password. You can enable automatic login as we will setup disk encryption later. | ||
+ | |||
+ | You can also use that password for the system administrator, | ||
+ | |||
+ | {{: | ||
+ | |||
+ | You should then arrive on the Installation Settings page, skipping the traditional partitioning and software selecting steps. First, go into Partitioning to enable encryption | ||
+ | |||
+ | {{: | ||
+ | |||
+ | Next we will use the Guided Setup, because it is easier and feature complete. | ||
+ | |||
+ | {{: | ||
+ | |||
+ | Now enable Disk Encryption and enter a strong passphrase that will be asked every time you start your computer. | ||
+ | |||
+ | {{: | ||
+ | |||
+ | Next it will ask what File System to use for the Root partition, keep Btrfs. | ||
+ | |||
+ | Keep the defaults for any other options until you return to the Installation Settings menu. | ||
+ | |||
+ | Once encryption is setup, you can proceed to the install. Everything else that need to be configured will be configured later. | ||
+ | |||
+ | {{: | ||
+ | |||
+ | This will, again, take some time. So grab some chocolate 🍫 (because you're likely out of coffee at this point). | ||
+ | |||
+ | Once the install has finished, the system will automatically reboot... | ||
+ | |||
+ | {{: | ||
+ | |||
+ | And you did it ! openSUSE is installed ! Now the fun begins, let's make it secure and set things up. | ||
+ | |||
+ | ====== First boot ====== | ||
+ | |||
+ | Just after rebooting, you will be prompted by GRUB that will ask you for your encryption passphrase: | ||
+ | |||
+ | {{: | ||
+ | |||
+ | It may look at bit different for you, this is how it looks in my virtual machine. | ||
+ | |||
+ | Once grub has been unlocked, openSUSE will boot automatically after 10 seconds, you can press enter to speed up the process. | ||
+ | |||
+ | openSUSE will ask you your encryption passphrase one more time to unlock the rest of the disk, as you have only unlocked the boot partition so far, which uses an older version of LUKS. | ||
