Legacy BIOS doesn't have an understanding of partitions, it will just 
look for a bootloader in the MBR of the mass storage device chosen to 
boot from.

The active / bootable flag was (still is?) a Microsoft thing[1], Linux 
bootloaders never cared about it and can load operating systems 
regardless if the corresponding partition is marked active or not.

[1] as far as I recall it was used in DOS times to let the bootloader 
know which is the system partition, but it could be (ab)used for 
multi-booting ;)

Kind regards,
Andrei
