- Once you choose "Something else" installation option, it will take you to the partition screen. Use “-” button on that screen to delete partitions and “+” button to create them. Delete the existing Windows partitions (unless installing alongside Windows) and then create root (/), swap, home (/home), and ESP/EFI (50 MB). ESP/EFI depends on if you have UEFI turned on in your BIOS, otherwise you don’t need it (the installer will tell you if you need it). If you have multiple drives, please make sure you select the correct drive in the drop down menu at the bottom of that screen.
- For any size drive, min 15 GB for root (I recommend 20 but I’ve been doing 30 on my own machines), swap is twice your RAM, rest is home.
