The Preserve option is available if your system has an active UNIX partition with a clean root filesystem and a valid /etc/default/filesys file (see filesys(F)). This option retains the filesystem layouts from the previous installation, except for the root filesystem. It removes everything from the root filesystem and installs the new system, leaving all other data intact. To access the Preserve option, press <Space> at Hard disk setup in the Preparing your disk and choosing software window, then press <Space> again at Partitions & filesystems.
If the list of hard disk setup options does not include Preserve, the installation could not find an active UNIX partition with a valid root filesystem and /etc/default/filesys. To preserve your existing partitions and filesystems, see ``About the Interactive disk setup option''. When using the Interactive fdisk/divvy option to retain your previous hard disk layout, you must assemble the hard disk layout information from your previous system before beginning the new installation.
The Preserve option is also available for the second hard disk. See ``Upgrading a non-primary hard disk''.
