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

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

Unmount of all volumes on diskN was successful

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

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