    Well to complicate thing we now have EFI boot and and GPT partitioning. From the little we know from the OP's machine it appears to be MBR boot with the old MS partitions. Which limits it to 4 primary partitions so you must deal with extended partitions and logical partitions. With GPT that does not exist. Many people recommend pre -creating the partitions but really the Installer's partitioning tool is very good and you can take control and set things as you like or require. You do not have to take the Installer defaults. I have never missed by simply supplying it free un-partitioned space and letting it do it's thing. I suggest you use tools from the OS that created the partitioned to resize and remove them but if you don't give the installer some space to work with it will suggest resizing existing partition to free space. The installer is pretty good but not perfect in keeping you from shooting your own foot but it will do exactly what you tell it to so be sure you understand what your instruction will do.

    Note also that having a separate home is optional but highly recommended.

    I would like to make a couple of suggestions. Before you start try and move the contents of D:, E: and F: to drive C:. Immediately before you actually install do a Defrag in windows on drive C: 195GB should be enough for Windoze. Go ahead with the installation until you get to the Partitioning stage. Do not except the offered on but choose to modify it. I would suggest you use 'ext4' as fs and delete partitions sda3, sda4, sda5 and sda6 (which should be empty if you've moved everything to sda2. Create sda3 of about 40GB for / then create an extended partition with what’s left and on that create a swap file of 2GB and the rest for your /home. All of this is flexible and the sizes you'll have decide for yourself. I don't think you need GPT on less than 2TB hdd's. But you may have to check the disk alignment when you create the partitions. Don't forget you can play around as much as you like because until you give the 'install' command nothing is touched on your system and you can abort at any time.

    Many many Thanks for waiting for me to come back.

    I have deleted two partitions in Windows. Now left with C, E and F

    Can I give a space of about 300- 400 GB to openSuse and rest for windows.

    As requested the output to fdisk -l is as below

    linux@linux:~> fdisk -l
    Absolute path to 'fdisk' is '/usr/sbin/fdisk', so running it may require superuser privileges (eg. root).

    I also verified in Bios of this computer, both options are there
    UEFI
    Legacy

    and both are ticked

    Another try of installing openSUSE give me these messages.
    http://i.imgur.com/mjSrvay.jpg
    http://i.imgur.com/w3uYXqZ.jpg

    This is again deleting Windows from the computer.

    Does it mean that I have to delete Win 8.1 and reinstall it in UEFI mode (and how should I proceed in this scenario?)
    Presently I have removed all of my data from Windows to an external hard disk.

    Please guide.
    Thanks in advance.

    The partition you have to delete is sda5. And I mean delete, not format
    it. As long as it is there, and formatted as ntfs, Linux will not
    automatically offer to use it.

    Also, you can tell the installer somewhere, I think in the expert
    partitioner, to erase and use certain partitions:




    However, you may not be able to do this if the installation media boots
    in uefi mode. Try disabling uefi in the bios.

    An alternative is to install both systems in uefi mode, but you will
    need a real Windows installation disk, not a recovery media.

    You have NO free space on that drive. You have

    Code:
    /dev/sda4       921600000 1953521663 1031921664 492.1G  f W95 Ext'd (LBA)
    /dev/sda5       921602048 1953521663 1031919616 492.1G  7 HPFS/NTFS/exFAT
    Note that you now have one large logical partition in the extended taking up all the space in the extended. You need to delete/ remove/zap/resize that partition to give free space to install. Not sure how I can be clearer. You need FREE un-partitioned space. If not then the installer will want to make that free space. You do need the extended partition because things Windows (which version?) is installed in legacy and in legacy you can only have 4 primary partitions one can be extended which can contain logical. So you also must boot the installer in legacy mode NOT EFI mode

    You should have a boot menu in the BIOS/EFI problem is I can't tell you what key to press at boot to get to it since it is different on different hardware. Maybe F10 or F12 when you see the first boot screen.

    Not at all sure why Windows 8.1 is installed in legacy?? Did this come with the computer. If so that is odd.

    To re do Windows you must first backup any important data that may be on it and have a Windows install Disk. Note that to control a Windows install you must use a real Windows install disk not one that is an install image, maybe called rescue. Those tend to take the whole drive. But things could be adjusted later. In any case you need to install in EFI mode not legacy.

    If the first boot screen/menu of the install disk does not have options on the bottom you have booted into EFI mode. In legacy there are options shown at the bottom of the screens

    Smile Re: openSUSE different from other Linux OS for Intel NUC... Why? Need help for installation.

    Now I understood, the problem is with the installation of Win 8.1.
    I asked the person who had installed Win on my computer before I bought it. Probably when I upgraded it to Win 8.1 (or he himself) had installed it in legacy mode.
    I will arrange for a new Win 8.1 USB image and install it in UEFI mode.
    Then will return here again to get further help from the openSUSE experts.

    Many many Thanks once again.

    Still should not be a problem to install openSUSE in legacy mode. But in some ways EFI is simpler since there are no extended/logical partition to deal with. But in other ways more complex. With EFI install you should have a special EFI boot partition that is formatted FAT this holds the special EFI boot things for all OS's installed. In openSUSE this partition is mounted as /boot/efi. Also the installer should want to use grub2-efi boot code not the legacy grub2 code. Note that these should be the default if you boot the installer in EFI mode. Just be sure they are set. If you plan to use secure boot check the box for secure boot since that is not automatic. If sueing Windows 8x or higher be sure that the fast boot options is off in it. It will stop access to the Windows partitions from Linux if it is on.

    You sill have to provide free un-partitioned space for the second OS to install to. This is the problem you were having before so.....don't put things in the space you want to use for Linux!

    You will need space for swap, about the same size +- as memory, root, if default BTRFS then about 40gig if select ext4 then about 20-30 gig. then home which is where all your personal stuff goes so it is up to you.
