The &architecture; boot loader is called grub. Grub is a flexible and robust boot loader and a good default choice for new users and old hands alike. By default, grub will be installed on the UEFI partition/the Boot Record of the primary drive, where it will take over complete control of the boot process. If you prefer, you can install it elsewhere. See the grub manual for complete information. If you do not want to install grub, use the &BTN-GOBACK; button to get to the main menu, and from there select whatever bootloader you would like to use.
