Dear Jiri, excuse my about my delay. I was busy with an project in my company. When i bought my PC i installed Windows-7 on the first disk and afterwards OPENSUSE on the second disk. During the OPENSUSE installation GRUB was able to manipulate the MBR (on the first disk) and give my the change to decide which OS i would like to start. Before i start the upgrade to 13.2 i don't change my BIOS (boot order, fist DVD second sda) or other system parameters. Why can't use 13.2 the right disk sequece? I can't see an error in my configuration. Have a look to my new attachments please. Best Regards Dietmar
