Hi guys,
I am pretty new to opensuse, so sorry for the stupid question.
Today i accidentally overrite the opensuse boot loader from /dev/sda with my debian boot loader.
Debian found opensuse using os-probe but i cant seem to boot into opensuse.
I am getting
"/boot/vmlinuz-4.1.15-8-default not found"
message.

But when i checked the opensuse partition the all files are there including
"vmlinuz-4.1.15-8-default" file.

Since my debian is 32 bit but opensuse is 64 i currently can't chroot into opensuse to reinstall kernel.
I am using debian 8(ext4 filesystem) and opensuse 42.1(btrfs filesystem).
my debian 8 has grub2 bootloader.

Please help me with this problem.

Thanks

I am currently downloading Ubuntu 64 bit so I can chroot to opensuse.
Currently I can't able to select the vmlinuz image of opensuse from the Grub console also.
I don't know what is the problem because the file is there in /boot directory.


Edit:
It seems after another "update-grub" opensuse entry has been removed from boot menu.

I finally solved the problem without using ubuntu, the problem was debian grub2 could not able to detect opensuse kernel in btrfs file system.
so i added
menuentry "chainload to opensuse " {
set root=(hd0,4)
chainloader +1
}

to "/etc/grub.d/40_custom" so now i can start opensuse boot loader from this menu entry .
