Ubuntu – What does it mean for Linux to erase disk space in Linux


I am installing Linux on Virtual Box but it says that the computer currently has no detected Operating Systems. What would you like to do?

1) Erase disk and install Ubuntu
Warning: This will delete any files on disk.

What should I do?

This is rather by design. You're inside a virtual computer. The disk that the Ubuntu installer can see is a virtual disk created and hosted by VirtualBox. In reality it's just a file sitting around on the host filesystem.

When VB creates a new one of these disks they have no partitioning and no filesystems or files. The Ubuntu installer is just echoing this state.

What should you do? Format and install.
