1First and foremost, before beginning the installation process, MAKE 2SURE YOU HAVE A RELIABLE BACKUP of any data on your hard disk that you 3wish to keep. Repartitioning your hard disk is an excellent way to 4destroy important data. 5 6The OpenBSD root partition must reside completely within the BIOS 7supported part of the hard disk -- this could typically be 504MB, 2GB, 88GB or 128GB, depending upon the age of the machine and its BIOS. The 9rest of the OpenBSD partitions can be anywhere that hardware supports. 10 11If you plan to dual boot, use the other operating system's "fdisk" program 12or partition editor to create at least one of the partitions to be used for 13that operating system. If that operating system is already set up to use the 14entire disk, you will need to make space available. Windows can resize its 15own system partition. In the control panel, search for "partition": this 16will lead you to the system administration tool. You do not have to create an 17OpenBSD partition at this time; the OpenBSD installation will give you an 18opportunity to create the partition needed for OpenBSD. 19 20 21Your hard disk is now prepared to have OpenBSD installed on it, and 22you should proceed with the installation instructions. 23
