- | Currently there are only instructions for booting from a USB stick, however, these instructions should serve as a good point of reference for installing on other media (such as SSD's or hard disks). | ||
- | |||
- | Materials needed: | ||
- | |||
- | * USB Stick | ||
- | * image.wic file (prebuilt or custom) | ||
- | * x86 based PC with the ability to boot from USB (any reasonably modern PC should be able to do this) | ||

- | ==== Identifying the USB Stick ==== | ||
- | |||
- | Plug in the USB Stick and identify the corresponding block device (''/ | ||

- | |||
- | |||
- | The easiest way to identify the right block device is usually it's size. | ||
- | In the example output above, we are looking for a 4GB USB Stick. | ||
- | We can infer that the USB Stick is ''/ | ||

- | If there are multiple devices of the same size as the USB stick it may be necessary to run '' | ||

- | ==== Writing the image to the USB stick ==== | ||
- | |||
- | **WARNING: Writing the image to the USB Stick will erase all content!** | ||
- | |||
- | **WARNING: Make absolutely sure you have identified the correct device! dd will not hesitate to override your OS drive if you tell it to!** | ||
- | |||
- | Use the following command to write the image to the USB stick | ||
- | modifying ''/ | ||
- | < | ||
- | sudo dd if=/ | ||
- | sudo eject /dev/sdX | ||
