Unetbootin works by altering the image and placing a boot loader on it. For this reason, it cannot work with UEFI and the installation guides for other distributions (incl. Debian and Fedora) recommend against using it. Since dd writes the image verbatim to the drive, and not just the files, it is not necessary to change the label after using it for UEFI installations. vcunat: tiny changes to the PR. Close #14139.

<para>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/sdb</replaceable></command>. Be careful about specifying the
|
|
correct drive; you can use the <command>lsblk</command> command to get a list of
|
|
block devices.</para>

|
|
|
<para>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. For
|
|
non-UEFI installations, you can alternatively use
|
|
<link xlink:href="http://unetbootin.sourceforge.net/">unetbootin</link>. If you
|
|
cannot use <command>dd</command> for a UEFI installation, you can also mount the
|
|
ISO, copy its contents verbatim to your drive, then either:
