The "bootable" flag in the partition table is only checked and used by
the DOS/Windows boot sectors. GRUB, LILO, and GRUB2 ignore it, and IIRC
only LILO needs to have the kernel/initrd within the BIOS-addressable
area of the disk (used to be the first 8G or first 32G, is larger now.)

This seems like a horrible idea to me.

This seems odd--why is there a bunch of empty space between sda5 and
sda6? You don't need 2 swap partitions; distros can share swap
partitions.

Is udev running? What does "ls -l /dev/sd*" tell you? If udev or
systemd isn't running, then the device node /dev/sda6 may not have been
created. "mknod /dev/sda6 b 8 6" will create it manually. But if it's
not showing up, then you should find out why udev or systemd isn't
running. Having device nodes automatically added when new devices are
plugged in works and is useful.
