Important:By default, the installation will not make any changes to the disk(s) before the following message: Your changes will now be written to disk. If you have chosen to overwrite existing data, it will be PERMANENTLY ERASED. Are you sure you want to commit your changes? The install can be exited at any time prior to this warning. If there is a concern that something is incorrectly configured, just turn the computer off before this point and no changes will be made to the system's disks. This section describes how to boot the system from the installation media which was prepared using the instructions in Section 2.3.1, “Prepare the Installation Media”. When using a bootable USB stick, plug in the USB stick before turning on the computer. When booting from CD or DVD, turn on the computer and insert the media at the first opportunity. How to configure the system to boot from the inserted media depends upon the architecture. These architectures provide a BIOS menu for selecting the boot device. Depending upon the installation media being used, select the CD/DVD or USB device as the first boot device. Most systems also provide a key for selecting the boot device during startup without having to enter the BIOS. Typically, the key is either F10, F11, F12, or Escape. If the computer loads the existing operating system instead of the FreeBSD installer, then either:
On most machines, holding C on the
keyboard during boot will boot from the CD.
Otherwise, hold Command+Option+O+F, or
Windows+Alt+O+F on non-Apple® keyboards. At the
Once the system boots from the installation media, a menu similar to the following will be displayed: By default, the menu will wait ten seconds for user input before booting into the FreeBSD installer or, if FreeBSD is already installed, before booting into FreeBSD. To pause the boot timer in order to review the selections, press Space. To select an option, press its highlighted number, character, or key. The following options are available.
The boot options menu is divided into two sections. The first section can be used to either return to the main boot menu or to reset any toggled options back to their defaults. The next section is used to toggle the available options

After making the needed selections, press 1 or Backspace to return to the main boot menu, then press Enter to continue booting into FreeBSD. A series of boot messages will appear as FreeBSD carries out its hardware device probes and loads the installation program. Once the boot is complete, the welcome menu shown in Figure 2.3, “Welcome Menu” will be displayed. Press Enter to select the default of to enter the installer. The rest of this chapter describes how to use this installer. Otherwise, use the right or left arrows or the colorized letter to select the desired menu item.

The live version is described in Section 2.11, “Using the Live CD”. Tip:To review the boot messages, including the hardware
