Installer
Our installer image simplifies the process of performing remote installations.
Follow our step-by-step guide to create and transfer this image onto a bootable USB drive.
!!! info If you already have a NixOS machine you can ssh into (in the cloud for example) you can skip this chapter and go directly to Configure Machines.
Step 0. Prerequisites
- A free USB Drive with at least 1.5GB (All data on it will be lost)
- Linux/NixOS Machine with Internet
Step 1. Identify the USB Flash Drive
-
Insert your USB flash drive into your computer.
-
Identify your flash drive with
lsblk
:lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS sdb 8:0 1 117,2G 0 disk └─sdb1 8:1 1 117,2G 0 part /run/media/qubasa/INTENSO nvme0n1 259:0 0 1,8T 0 disk ├─nvme0n1p1 259:1 0 512M 0 part /boot └─nvme0n1p2 259:2 0 1,8T 0 part └─luks-f7600028-9d83-4967-84bc-dd2f498bc486 254:0 0 1,8T 0 crypt /nix/store
!!! Info "In this case the USB device is
sdb
" -
Ensure all partitions on the drive are unmounted. Replace
sdb1
in the command below with your device identifier (likesdc1
, etc.):
sudo umount /dev/sdb1
=== "Linux OS" ### Step 2. Flash Custom Installer
Using clan flash enables the inclusion of ssh public keys and disables ssh password authentication.
It also includes the language and keymap currently used into the installer image.
```bash
clan --flake git+https://git.clan.lol/clan/clan-core flash flash-installer --disk main /dev/sd<X>
```
!!! Danger "Specifying the wrong device can lead to unrecoverable data loss."
The `clan flash` utility will erase the disk. Make sure to specify the correct device
=== "Other OS" ### Step 2. Download Generic Installer
```shellSession
wget https://github.com/nix-community/nixos-images/releases/download/nixos-unstable/nixos-installer-x86_64-linux.iso
```
### Step 3. Flash the Installer to the USB Drive
!!! Danger "Specifying the wrong device can lead to unrecoverable data loss."
The `dd` utility will erase the disk. Make sure to specify the correct device (`of=...`)
For example if the USB device is `sdb` use `of=/dev/sdb`.
Use the `dd` utility to write the NixOS installer image to your USB drive:
```shellSession
sudo dd bs=4M conv=fsync oflag=direct status=progress if=./nixos-installer-x86_64-linux.iso of=/dev/sd<X>
```
Step 4. Boot and Connect to your network
After writing the installer to the USB drive, use it to boot the target machine.
!!! info Plug it into the target machine and select the USB drive as a temporary boot device.
??? tip "Here you can find the key combinations for selection used by most vendors." - Dell: F12 (Boot Menu), F2/Del (BIOS Setup) - HP: F9 (Boot Menu), Esc (Startup Menu) - Lenovo: F12 (ThinkPad Boot Menu), F2/Fn+F2/Novo Button (IdeaPad Boot Menu/BIOS Setup) - Acer: F12 (Boot Menu), F2/Del (BIOS Setup) - Asus: F8/Esc (Boot Menu), F2/Del (BIOS Setup) - Toshiba: F12/F2 (Boot Menu), Esc then F12 (Alternate Method) - Sony: F11/Assist Button (Boot Menu/Recovery Options) - Samsung: F2/F12/Esc (Boot Menu), F2 (BIOS Setup) - MSI: F11 (Boot Menu), Del (BIOS Setup) - Apple: Option (Alt) Key (Boot Menu for Mac) - If your hardware was not listed read the manufacturers instructions how to enter the boot Menu/BIOS Setup.
During Boot
Select NixOS
to boot into the clan installer.
After Booting
For deploying your configuration the machine needs to be connected via LAN (recommended).
(Optional) Connect to Wifi
If you don't have access via LAN the Installer offers support for connecting via Wifi.
iwctl
This will enter iwd
[iwd]#
Now run the following command to connect to your Wifi:
# Identify your network device.
device list
# Replace 'wlan0' with your wireless device name
# Find your Wifi SSID.
station wlan0 scan
station wlan0 get-networks
# Replace your_ssid with the Wifi SSID
# Connect to your network.
station wlan0 connect your_ssid
# Verify you are connected
station wlan0 show
If the connection was successful you should see something like this:
State connected
Connected network FRITZ!Box (Your router device)
IPv4 address 192.168.188.50 (Your new local ip)
Press ++ctrl+d++ to exit IWD
