Ubuntu – Ubuntu Installation Root partition


I have decided to install Ubuntu for office, programming and GFX along Windows 8.

I have made a USB – Bootstick and so on, created a 100GB partition for Ubuntu, so I wanted to install it on this partition, but he asks me for a root partition, but i still dont get what to do now.

Can u help me?

I am using Windwos 8 and have a Mainboard with UEFI.

Update for Ubuntu 18.04 and above

New installations of recent versions of Ubuntu does not use a separate swap partition any more. They use a swap file by default.

Some Basics

Ubuntu needs at least two partitions to work well. One is called the root partition denoted by / and is formatted ext4 and the other is called Swap with its own format. Windows does not understand these formats.

So you can't use Windows to create these partitions.

What to do?

The partition you created in Windows is not suitable for Ubuntu. Delete the 100GB partition you have created and leave the space unallocated.

When you install Ubuntu, it will find the unallocated space and create the partitions it needs automatically. The Swap will be a small partition (2-4 GB) used as virtual RAM and the rest of 100GB will be /.
