GRUB 2 not showing up when dual booting + other OS not recognized

Recently I received an old laptop Sony Vaio VGN-C13G (originally it was released in 2006). Added more memory. Now it has 3GB. Than I decided to install 2 Linux distros: SUSE 13.1 and Mint MATE 17. And some problems started.
After any installation Grub 2 was not showing up. I followed many forum posts how to make it visible. I tried experimenting with different distributions: Ubuntu, CentOS, Mint.
To make sure that there were no leftovers I low formatted HD using
Code:

if=/dev/zero of=/dev/sda
Finally I created just 2 partitions. Installed Linux Mint on /dev/sda1 and Open SuSE on /dev/sda2.
Still Grub 2 was not showing. When I changed to Legacy Grub (using YAST) I can see its menu but without Linux Mint.
I tried also tried YAST>Boot Loader Settings>Other>Reread configuration from disk.

Please have a look at some more info which might be related to my problem:

I wonder if its possible that Grub 2 cannot work on my laptop? Do I really have to stick to Legacy Grub? Would be possible to add Linux Mint to its menu?
Thank you for any help and recommendations how to rectify my problems.
