'''La grande question est : Quelle méthode de boot utiliser ?''' Voici comment savoir.
Principle 1 - Old School: If you can reliably boot System Rescue CD and it shows you an initial light blue menu, you are booting the CD using the BIOS , and it's likely that you can thus boot Funtoo Linux using the BIOS. So, go old- school and use BIOS booting, '' unless'' you have some reason to use UEFI , such as having a >2.2TB system disk. In that case, see Principle 2, as your system may also support UEFI booting.
;Principle 2 - New School: If you can reliably boot System Rescue CD and it shows you an initial black and white menu -- congratulations, your system is configured to support UEFI booting. This means that you are ready to install Funtoo Linux to boot via UEFI. Your system may still support BIOS booting, but just be trying UEFI first. You can poke around in your BIOS boot configuration and play with this.
