OpenSUSE 13.1 boot manager to dual boot with Win 7

Hey all,
New to Linux in general, doing some reading but not finding a clear answer to the best way to do this.
I installed Win 7 SP1 on Latitude E6400 sizing the drive partition to half of 160.
Then installed SUSE 13.2 on unused and it only boots to SUSE, no mention of Windows at boot screen? What am I missing?

11/15 - Thanks to all for the suggestions. I just got around to working on it again and did a reinstall of the OpenSuse and now it see's the Win7 and allows choosing which OS to boot and works it should!!
Appreciate the pointers!

I haven't used Opensuse for some time but I think in YaST you should have an option under System/Bootloader to add entries. You could try running the grub-mkconfig command as root. Did you install Opensuse in EFI or MBR?

I too haven't looked at OpenSUSE in a long time, but a quick search found this. Looks like it's unresolved.
For the OP, os-prober is the tool that finds any operating systems installed so they can be added to the boot menu.

I've also seen another post that suggests a system update may fix things.

I can't be of much use in resolving the issue, but I can say that it should work exactly like you expect, and the 12.3 and both 13.1 installations I've done on various laptops have identified the Windows partition without issue and added it to the boot menu automatically.

I can only think that there must be something odd about your Windows installation. Is it EFI? Was it an OEM Windows 7 installation or from a disk, or was it an upgrade from another version of Windows? Is it possible you had an unclean shutdown of Windows right before attempting to install OpenSUSE, so it wasn't able to mount the ntfs partition to verify there was an OS there?

Is this OpenSUSE 13.1 or 13.2 (your post mentions both)?

Boot from your Windows disc and repair the installation. This will leave you with a "Windows Only" setup. Boot again from the OpenSUSE media specifically to install GRUB and be sure that it presents an option for both OS'es. You'll need to install it into the MBR of the boot drive.

Back when I was booting both Opensuse and Fedora, it seems like both systems needed me to mount all OS partitions before I updated grub. Otherwise grub wouldn't see them.

So I would try, in Opensuse mount your windows partition, then run this command:

grub2-mkconfig -o /boot/grub2/grub.cfg
