This is not a question on how to install Ubuntu or how to use manual partitioning during installation but is a question on access rights and how not to let them bite you in the lower abdomen… 😉
This question will not help you how to make partitions on your disk, but will tell you what to do in step 4 of the installation process, depending on your personal use case, so choose one of the following:
- I'm a beginning Windows and/or beginning Ubuntu user
- I know Windows well but Ubuntu is new / I know Ubuntu well, but Windows is new.
- I'm an expert at both Ubuntu and Windows!
Note: The above questions can also be used with multiple disks, but the examples in the answers are given for one disk.
