Can't install 13.1

I can't install opensuse 13.1 :'( on dvd and gnome cd it gives me error about grub and when i manually install grub system is really messed up. and on kde, live installer is not even starting. What can i do? i don't know it's uefi or not but i checked on linux mint it's not uefi and on my bios setting there is nothing about uefi.

but i checked it on mint and it says it's not:



I'm downloading network version openSUSE-13.1-NET-x86_64.iso is it easy to install?
