Once Fluxuan Booted UP you will see the Welcome Message - MINIMIZE WINDOW.

OPEN TERMINAL and run

 lsblk 

so you can see what is available and what partition you want to use .
I have highlighted what i will use .
( First Partition is for SWAP second is already installed Fluxuan , you may have other OS , third will be my target  )

I Know my target now so i can close the terminal Raise up Welcome Screen and click Install-Fluxuan

When You click Install-Fluxuan a Terminal window will start with the installer Welcome Screen.
Just Hit ENTER.

Select a DRIVE from the next menu list using UP and DOWN arrows on your KEYBOARD and press ENTER.

In the next menu list you will have 2 options - 1 Install Fluxuan | 2 Install Fluxuan on existing partition.
I want to install Fluxuan on a Partion so i press DOWN arrow to select OPTION 2 and hit ENTER-> Install Fluxuan on existing Partition

You will see a menu to select the desired Partition in my case will be /dev/vda3 as i seen and choose from the start.

You will see Fluxuan Formating and preparing partition then Install on your Drive.

Now is time to input desired HOSTNAME in my case will leave default you can use backspace to delete and write what you want and hit ENTER

Next you can select your Timezone use UP DOWN arrows and ENTER.

Next Choose Language -UP DOWN arrows SPACE selects if you want multiple Languages TAB to jump on OK button and ENTER

Now let`s select our Keyboard , by now you probably got used to UP DOWN ENTER so go on

Pick a ROOT PASSWORD

Input Desired USERNAME

Pick a password for your USENAME

After Finish screen will appear just hit ENTER and the Installer will close.

Now I know Fluxuan is installed on my vda3 partition now let`s create Dual Booting.
Boot into your main Operating System ( LINUX ).
Open File manager and click to mount the partition you have installed Fluxuan on enter password when requested i use pcmanfm.

Open Terminal and check if os-prober is installed .

sudo os-prober

You should get a reply like the next picture if it is installed , if not you can install it by running

sudo apt install os-prober

or what package-manager you have

Now we have to enable it in grub configuration so in Terminal run the next command and remove "#" from "#GRUB_DISABLE_OS_PROBER=false"
It should look like in the next picture.

sudo nano /etc/default/grub

Use CTRL+O to save and CTRL+X to close nano after editing

Now we can run

sudo update-grub

Next open again grub configuration and restore "#"

sudo nano /etc/default/grub

Use CTRL+O to save and CTRL+X to close nano after editing

Now reboot your Operating system and you will see in the Grub Menu the new Fluxuan on Partition /dev/vda3 in my case choose and hit ENTER

I hope this HOW-TO will help and for any issues post a new TOPIC in the INSTALLATION section.
THANK you for being there.
