"The Slackware install images ship with fdisk and cfdisk, which
let you partition your hard drive if needed. These aren't difficult
to use, but can be daunting to the first time user. As an
alternative, Parted Magic is a nice small utility distro designed
primarily for partitioning and rescuing drives.
"Slackware's first install screen may be intimidating to new
users as well. After booting the first install CD, one logs in as
root and types setup, which bring up a screen of headings such as
ADDSWAP, TARGET, and SOURCE. Beginning with ADDSWAP will start the
installation process. Highlight ADDSWAP and press Enter to be
guided through setting up your swap partition. From there you will
be guided through setting up the install partition, package
selection, network options, boot loader, and root passwords. At the
end you are instructed to press Ctrl-Alt-Del to reboot. It's the
same basic process as found in all Linux installers."
