<title>Booting from a USB Drive</title>

<para>

For systems without CD drive, the NixOS live CD can be booted from a
|
|
USB stick. You can use the <literal>dd</literal> utility to write
|
|
the image: <literal>dd if=path-to-image of=/dev/sdX</literal>. Be
|
|
careful about specifying the correct drive; you can use the
|
|
<literal>lsblk</literal> command to get a list of block devices.

Using the 'raw' <literal>rdiskN</literal> device instead of
|
|
<literal>diskN</literal> completes in minutes instead of hours.
|
|
After <literal>dd</literal> completes, a GUI dialog "The disk
|
|
you inserted was not readable by this computer" will pop up,
|
|
which can be ignored.

The <literal>dd</literal> utility will write the image verbatim to
|
|
the drive, making it the recommended option for both UEFI and
|
|
non-UEFI installations.
