If so, please describe. In case of MBR/BIOS boot (man boot, man fdisk) you can use boot0 manager (man boot0cfg). You can also use Linux/Win GRUB to have fancy GUI selection menu (installed on a separate partition). In case of UEFI (man uefi, man gpart) it is a bit different and still evolving. Each OS has dedicated EFI Boot partition that contains the bootstrapping loader, so directly from the Mainboard Setup program you can select UEFI boot and the default partition to boot. I use FreeBSD by default so I need no fancy menu, to boot the another OS I press F8 at boot and select different OS. This is the most generic way. EFI boot partitions may be located on a single drive or different drives, Motherboard should detect all of them for selection. It is also important that usually you need to disable Secure Boot in order to use unsigned bootloaders or add bootloader sign keys to the Motherboard (via Setup program) in order to boot custom signed bootloader in a secure way. Ventoy (https://www.ventoy.net/) can also manage boot keys. In case of UEFI boot you can also use fancy GUI menu with: 1. Clover: https://sourceforge.net/projects/cloverefiboot/ 2. reFInd: https://www.rodsbooks.com/refind/ 3. Ventoy: https://www.ventoy.net/en/ Have fun :-) -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
