Help with Dual Booting Windows 8.1/Linux

Hi guys, I have read several different set-ups on installing Linux Ubuntu with Windows 8,1. Here is my particular idea of how I think it should be done. Can someone tell me if I have this right or wrong?

This is what I what I want to achieve:
Dual boot Win 8.1 and Linux Ubuntu14.04 LTS on SSD

I want to use the GRand Unified Bootloader (GNU GRUB) to select between either Windows 8.1 or Linux Ubuntu on start-up.
Is the GNU GRUB a part of Ubuntu program or do I have to add it as a separate independent program?

What I did is burned a Linux Ubuntu ISO DVD. I can use this DVD to set-up the installation process. The DVD has set-up perfectly.

I have a Samsung 840 240GB SSD. This is Disk 0. I named Disk 0 "Windows SSD (C:)". Disk 0 is partitioned into a Recovery partition, EFI System partition and the Boot/OS partition.

I THINK I need to 'Shrink' my "Windows SSD (C:)" drive in order to creat a new partition for my Linux OS.
1) Is this correct?
2) Do I need to re-partition my new partition into a total of 3 separate partitions for the Linux OS/boot, EFI System/BIOS, Recovery or will Linux automatically create these new partitions during the installation process?

I also read that I needed to change some settings in my ASUS UEFI.
1) Disable Fast Boot - I did this already.
2) Disable Secure Boot - Do I really need to do this?
3) Put Windows Boot Manager at the bottom of the boot priority order.- Do I really need to do this?
4) Enable the key for one-time boot priority changes - ???
Save and exit.

Run installation procedure.

Does all of this seem correct or am I missing or doing something wrong?
Thanks guys for all your help.


UPDATED:
I think I may NOT be able to create all the new partitions necessary. I already have 3 'Primary' partitions. I think I am able to create one more 'Primary' partition for a total of 4 on one disk. I can add other 'dynamic' or 'logical' (aka 'Extended') partitions but that would mean that I would have to convert my other 'Primary' partitions. The Disk Management system is not very happy when you go beyond 4 partitions to 5 partitions. It will automatically re-convert your 'Primary' partitions to logical partitions.

Can someone confirm my concerns?
Thanks

You can do everything you need to do from the Ubuntu installation. You didn't need to create any partitions beforehand. It does that for you, and it just makes it more complicated when you try to do everything manually. It also installs GRUB for you. Installing Ubuntu in a dual boot is much easier than you're making it.

If I were you, I would try to add everything back to the Windows partition like it was, and let the Ubuntu installation take care of it for you. You should be able to choose during the installation whether you want to use the entire disk and erase Windows, or use part of the disk and dual boot. I haven't installed it for a while, but it used to give you a slider for you to decide how much to allocate to Windows and...

I haven't installed it for a while, but it used to give you a slider for you to decide how much to allocate to Windows and Ubuntu. It will also create a small swap partition for you.

Also, you don't really need all of the partitions you might think you need. Some people are partition freaks, and they like to put everything on its own partition. But I always just put everything on one large partition, like Ubuntu does by default.

Also, you'll probably get a lot better help for Ubuntu over at ubuntuforums.org than you will on a Windows 8 subforum. ;)

Thanks for your answer. I have not created any partitions yet. I only have my original Windows 8.1 set-up (it has 3 naturally created partitions on the disk). It seems like all I need to do is just insert my Ubuntu installation DVD and follow the instructions.

I will also take you advice on ubuntuforums.org.
