I have a laptop with 1 TB hard, and I want to install dual boot Windows 10 / GNU/Linux openSuse Leap 42.1.
I tried making 4 primary partitions for Linux, boot, swap, system, data, and installation works. But Windows 10 installer won't let me install to the rest of the disk.
I tried installing Windows first: 3 partitions, 500 MB, system, data. Linux does not allow me to create new partitions.
On an older laptop I have these two systems working, but the partitions were already made by Windows 7 and by openSuse 13.2. I have 3 Windows: 100 MB, system, data, and an extended partition with swap, system and data for Linux.
It might be better to install Windows 7 first , create new partitions for Linux and then upgrade to Windows 10.
Thanks for answering me. This is what I wanted to avoid :) A useless Windows 7 installation, when I have a bootable Windows 10.
I think I managed. I need to make the boot UEFI from BIOS, then Windows can install in the GPT partition created by the GNU/Linux. I did not install Windows yet, so I am not fully assured.
