The "Something else" option in Linux installation

I won't be very detailed in this post, it's more of a future reference for my future self in case I need to go through this again. In the "References" section of the post, I will leave some links to content by people who have explained what is being done in more detail. Still, I hope it can help someone else as well.

How it does not happens every day, I always forget how to setup the partitions in Ubuntu (or other OS's) when I need reinstall the system keeping my dual boot in order.

I recommend you format your Linux system (ig Ubuntu) in Windows, and when installing the new one, use the option "alongside". It's more safe and simple.

But we are here to use the "Something else" option. Below is a simple step by step of how use it.

1. The biggest space (which will be for the operating system) use type ext4. For its mount point put the value /.
2. Create a "swap" partition with 2048MB (2GB)
3. Setup the field Device for boot loader installation to your Windows boot manager
4. And you are ready to "install now"
