This is necessary to allow booting on multiple systems each requiring different modules in early userspace.

Before creating the initial RAM disk, in /etc/nf move the block and keyboard hooks before the autodetect hook.

If you run Windows or macOS, download VirtualBox, install VirtualBox Extensions, attach your removable medium to a virtual machine running Linux (either already installed or via a live ISO), and point the installation into the now attached drive while using the instructions at the Installation guide.

If booting from a Live USB, the installation cannot be made to the same removable medium you are booting from.

An Arch Linux CD/USB can be used to install Arch onto the removable medium, via booting the CD/USB and following the installation guide.

If you have another Linux computer available (it does not need to be Arch), you can follow the instructions at Install from existing Linux.There are various ways of installing Arch on removable media, depending on the operating system you have available: However, if you plan to install desktop environments such as KDE, 3 GiB or more is recommended.

A modest set of packages will fit, leaving a little free space for storage. Note: At least 2 GiB of storage space is recommended.
