I am trying to change from Windows 10 to Ubuntu entirely right now, but I get confused on the partition of the disks.

What I have in Windows 10:

  1. 4GB RAM
  2. 1TB HDD, C: drive ~600GB (Windows, desktop, program files, etc), D: drive ~400GB (For personal files, movies, music and backup, etc)

I researched some information of partition on the Internet.

I think I need 8GB /swap?, /boot (optional?), /root?, /home?

How many? and is it optional? When I change to Ubuntu, should /home be larger than /root?

*I want to format C: drive but keep D: drive

Thank you for you guys answering me.

mandatory is just the root partition( / ); however, many like to have a seperate /home partition so they can do clean installs without losing data in /home.
The most common installations use a /swap partition, though a swapfile can be used instead. If you will use hibernate, 8GB swap is a common recommendation for 4GB RAM. If you won't hibernate less will work.

A good partitioning scheme would be:
/ 20GB
/swap 8GB
/home 40GB the remaining space can be divided into data, backup, and other partitions as you desire.

If you are completely removing windows, I would recommend copying the data from the windows data partition to a linux partition since NTFS error correcting support is weak in linux.

Data partition can be auto mounted or manually mounted as needed. An automount data partition can be setup when installing. You just have to manually define a mount point for it.

From the comments...

There are probably a few different ways to do this. First, I'd recommend keeping Windows 10, and setting up a dual-boot configuration. Shrink your C: drive to make room for Ubuntu. Install Ubuntu with the default configuration, and don't worry about custom partitioning for /boot, /root, /home, etc.

The reason that I recommend keeping W10 in a dual-boot config is because at times, you will need Windows to install things like BIOS/UEFI updates (some exceptions), run Windows-only apps, etc. Just because it's there, you don't have to run it... and I don't blame you for trying to switch :-) If the D: drive is also NTFS format, you can keep it, and share files between W10 and Ubuntu. Lastly, if you're going to need vendor support, you'll have to keep Windows, as they won't support Linux.

I didn't format C: because I'm recommending that you keep W10 AND Ubuntu at the same time, in a dual-boot config. You can boot to which ever OS you want.
