-      - For default filesystem press "enter" 4 times on all parameters (Partition number, First sector, Last sector and Current type)  
+    - Type `n` again to create another new partition and press "enter".  
+    - Press "enter" on default Partition number again.  
+    > NOTE: The value should correspond with how many partitions we are making. Example should be `default 2` if this is the 2nd partition otherwise put in `2` or whatever correct value needed and press "Enter".  
+    - Press "enter" on default First sector again.  
+    - Press "enter" on default Last sector this time to use the remaining space if just creating one other partition `/root` otherwise if more seperate partitions will be created, example: `/home` and/or `/swap` and/or `/var` then put in a fixed amount of space by repeating step ***4.3.*** for each but make sure to do `/root` last if no seperate `/home` partition or `/home` last if specified and let it have the remaining space by just pressing "Enter". Another option is to specifiy space for the last created partition (`/home`/`/root`) therefore we have leftover unused space to use in the future to possibily allocate to existing or create more partitions.  
+    > NOTE: General recommendations but can greatly differ 
+    `+60G` for /root
+    /root recommended at least 15-20G, more is better. If `/home` is created then user-data will be stored in `/home`. `root` will usually store what's installed from the package manager(s) therefore if many packages/software will be installed don't be afraid to increase the size, example `+80G` or more if disk has enough space.
+    `+4G` or general rule of thumb is 1x2 of RAM. for /swap though can use swapfile
+    `+10G` for /var or /var/tmp

+      - Press "enter" if default filesystem but when creating a `swap` partition then put in `8200` to set a Linux swap partition and make sure to just press "Enter" on this option again when repeating this step to create `/root` or `/home` etc...
