i'm trying to make a multi-boot disk (5 linux distros) with only one /boot partition. Problem is that the guy before me that made this disk didn't bother to create that separate boot partition, so i created one at the end of the disk, but now i cannot edit the grub menu from other distros except the last one i installed. I assume i need to point all the distros to that one /boot partition, but i have some questions; 1 - can/should I put all the kernels for the different distros in that one partition, can i separate them in folders? 2 - how do i point each distro to that /boot partition?
The distros i have installed are as follows sda1 RHEL 6.7 sda2 RHEL 7.0 sda3 RHEL 7.1 sda4 extended partition sda5 SUSE 12 sda6 Fedora 22 sda7 Swap sda8 /boot
