+
+Partitioning your disk simply refers to the act of breaking up your
+disk into sections. Each section is then independent of the others.
+It's roughly equivalent to putting up walls inside a house; if you add
+furniture to one room it doesn't affect any other room.

+this into a DASD or VM minidisk in the &arch-title; world. Also a machine

+and want to stick Linux on the same disk, you will need to repartition
+the disk. Debian requires its own hard disk partitions. It cannot be
+installed on Windows or MacOS partitions. It may be able to share some
+partitions with other Linux systems, but that's not covered here. At
+the very least you will need a dedicated partition for the Debian
+root.

+
+In general, changing a partition with a file system already on
+it will destroy any information there. Thus you should always make
+backups before doing any repartitioning. Using the analogy of the
+house, you would probably want to move all the furniture out of the
+way before moving a wall or you risk destroying it.

+If your computer has more than one hard disk, you may want to dedicate
+one of the hard disks completely to Debian. If so, you don't need to
+partition that disk before booting the installation system; the
+installer's included partitioning program can handle the job nicely.

+
+If your machine has only one hard disk, and you would like to
+completely replace the current operating system with &debian;,
+you also can wait to partition as part of the installation process
+(<xref linkend="partman"/>), after you have booted the
+installation system. However this only works if you plan to boot the
+installer system from tapes, CD-ROM or files on a connected machine.
+Consider: if you boot from files placed on the hard disk, and then
+partition that same hard disk within the installation system, thus
+erasing the boot files, you'd better hope the installation is
+successful the first time around. At the least in this case, you
+should have some alternate means of reviving your machine like the
+original system's installation tapes or CDs.
+
+</para><para>
+
+If your machine already has multiple partitions, and enough space can
+be provided by deleting and replacing one or more of them, then you
+too can wait and use the Debian installer's partitioning program. You
+should still read through the material below, because there may be
+special circumstances like the order of the existing partitions within
+the partition map, that force you to partition before installing
+anyway.

+If your machine has a FAT or NTFS filesystem, as used by DOS and Windows,

+
+If none of the above apply, you'll need to partition your hard disk before
+starting the installation to create partition-able space for
+Debian. If some of the partitions will be owned by other operating
+systems, you should create those partitions using native operating
+system partitioning programs. We recommend that you do
+<emphasis>not</emphasis> attempt to create partitions for &debian;
+using another operating system's tools. Instead, you should just
+create the native operating system's partitions you will want to
+retain.

+If you are going to install more than one operating system on the same

+Linux installation. Windows and other OS installations may destroy
+your ability to start Linux, or encourage you to reformat non-native
+partitions.

+In order for OpenFirmware to automatically boot &debian; the Linux
+partitions should appear before all other partitions on the disk,

+come <emphasis>before</emphasis> the other bootable partitions on the
+disk. (The small partitions dedicated to Apple disk drivers are not
+bootable.) You can delete the placeholder with the Linux partition
+tools later during the actual install, and replace it with Linux
+partitions.
