Learn how to prevent Windows 10 from blocking the installation process when using a disk.
You're facing a common issue when working with legacy systems. Since Windows 10 is installed on the same drive, you can still use a bootable USB or CD to install the older OS. Create a bootable media and boot from it instead of relying on the Windows 10 installation.
You're looking for an older operating system on a relatively old computer, but the storage device already runs Windows 10. You'll need to erase it completely before adding another OS. DBAN is suitable for this task (note: it deletes all data, so backups are essential).
