lhtuun,
It is a good idea to boot from GParted media prior to installation and create your own partitions, for example:
sda1.....ext4.....root.....say,15gb
sda2....swap....1.5gb
sda3....ext4....../home.....remainder of drive.
Follow this guide:

The interesting bit is where at 1c you should select
Custom install on existing partitions.
Use sda at 1a and ignore 1b.
At 2a use:
root...sda1
swap....sda2
home...sda3
The numbering may change but it will be obvious which partition is which from the size.
