[SOLVED] Dual boot with Windows 10

[stevedat]

Hi everyone,

First of all, a big thank to Linux Lite creator & its team members. 
I am running Linux Lite 2.6 on my Dell Inspiron N4050 and being happy with it.  ;D
However I need to use Windows for some stuff. I know that most of the stuff can find and work on Linux, but it's not all.
So I want to reinstall Windows on my machine.
The point is I decided to install Linux Lite 2.6 on my entire HDD (500GB). I separated my hard drive like that: /root (80GB), /home (400BG), and /swap (2GB) (there is only 3 partitions and amount numbers of GB on each partition is not accurate, just relevant numbers).
And now I am going to install Windows 10 and having a dual boot to pick up which OS to boot up when I want to run Linux Lite or Windows 10.  :
Can you guys guide me best ways to do it without losing any existing data at /home?
Re-seizing partitions by GParted takes long to complete - it was a painful experience. !_!
I think that I need a way fast & secured!  :-[

Thanks.
