After the system powers on, the Petitboot bootloader scans local boot devices and network interfaces to find boot options that are available to the system.
Petitboot returns a list of boot options that are available to the system. If you set up a DHCP server and provided the boot arguments or if you are using a media installation, your boot option is available. Select it and press Enter.
If you are using a static IP or if you did not provide boot arguments in your network boot server, you must provide the details to Petitboot.
