Install Windows dual-boot on existing Leap 42.3 system?

Hi, all! I just bought a used i7 desktop with OpenSUSE Leap 42.3 installed by the previous owner. The boot disk is a Crucial 120GB SSD.

I’d like to also put Windows 7 on this machine and make it dual-boot. I’m a relative n00b when it comes to OpenSUSE and would appreciate some tips and guidance.

Thanks.

What do you plan to do with it? 120GB could be somewhat crowded for multiboot with Windows, unless it’s just a test machine and/or won’t be loaded with optional software. Provide us output of

fdisk -l
cat /etc/fstab
inxi -SMGxx

so we have a better idea what you have to work with. (You may need to install inxi -> zypper in inxi, or use YaST).

Thanks for taking a look:
