+## Un-allocate Space
 
-Download and run Rufus:
+Ubuntu 20.04 requires `~8 GB` for complete disk installation, but you need to have more utilities. A space of `100 GBs` usually suffices, but that's your choice.
+
+If you're planning to use Ubuntu as your primary OS I would highly recommend partitioning your SSD drive, and giving up `150 - 200 GB` space instead.
+
+Refer here to understand how to do this step:

+
+Install Rufus, and upon starting the application should look like:

+
+Insert the external flash drive, Rufus would automatically detect it as _Device._\
+Under _Boot Selection_ choose the ISO file downloaded above.\
+Leave _Partition Scheme_ and _Target System_ as defaults.\
+Start the process.
+
+## Reboot and Change Startup Config
+
+Reboot the system, keeping the startup disk connected, and Enter BIOS Menu.\
+Reboot your system, and while it turns on, before your laptop's brand's icon shows up.&#x20;
+
+Repeatedly press the key (Keys to be pressed vary a lot, usually it is`F2`, confirm from ) until the BIOS Menu shows up, something like this:
+
+<img src="../../.gitbook/assets/image (1).png" alt="" data-size="original">
+
+Turn off `UEFI Secure Boot` and `Legacy Boot` (if available) settings.\
+Now in the _Boot Device Select Menu_ change the `Boot Order` to USB first.\

+
+### Load Ubuntu Installer from Drive
+
+While the USB-drive is connected, use that to load the OS.
+
+Ubuntu Installation wizard will greet you.\
+Rest steps should be kept as default unless you know what you're doing.\
+The steps where you have to take care are:
+
+* Tick the `Install third party softwares for graphics and Wifi hardware [...]`
+* Under Installation Type Menu, choose `Something Else` and under that, use the unallocated partitions you created in Step 2.
+
+#### Allocating Space
+
+Distribute the unallocated space to 3 partitions, `root`, `home` and `swap`(recommended, if low RAM device)\
+To create the first partition, the `root` partition, select the free space (the shrinking space from Windows created earlier), and hit on the `+` icon below. On partition settings use the following configurations and hit OK to apply changes:
+
+* Size = at least 15000 MB
+* Type for the new partition = Primary
+* Location for the new partition = Beginning
+* Use as = EXT4 journaling file system
+* Mount point = `/`
+
+{% hint style="info" %}
+It is recommended to place root partition onto primary partition on MBR scheme disks
+{% endhint %}
+
+Create the swap partition using the same steps as above.
+
+* Size = 512 MB to 4 GB
+* Type for new partition = Primary
+* Location for the new partition = Beginning of this space
+* Use as = swap area
+
+Create the home partition using similar steps. Use all the available free space left for the home partition size. The partition settings should look like this:
+
+* Size = all remaining free space
+* Type for the new partition = Primary
+* Location for the new partition = Beginning
+* Use as = EXT4 journaling file system
+* Mount point = /home
+
+{% hint style="info" %}
+You can allocate more partitions for `/boot`, `/tmp` and `/var`
+{% endhint %}
 
-Search for the Startup Disk Creator.
+Press `Install Now` after verifying that you're good to go.
 
-## Step 3: Complete the installation
+## Confirm Installation
 
-Go through the following tutorial to finish the installation procedure:
+Now rebooting should greet you with a GRUB menu, with a choice of going for Ubuntu or Windows booting. More detailed dual-booting tutorial [LINK](https://www.tecmint.com/install-ubuntu-alongside-with-windows-dual-boot/)
