Hello,
I'm reinstalling Ubuntu on my PC in dual-boot with Windows 10. I've chosen the partition manually, but I'm getting a message saying "no filesystem has been chosen as root," and I don't know what to do. Thanks in advance for your help.

Hello,

When partitioning, you need to describe the Linux partitions.

- Generally, you create three partitions: /, /home, and swap. In practice, only / is necessary for an installation (although the other two are strongly recommended).

- It’s not enough to declare and format the partitions for the installer to know what to do with them: you also need to specify their future roles (typically, /, /home, and swap).

Here, your mistake means that you did not declare which partition would take on the role of /.

Good luck!
