Stuck in installation

I am trying to install Zorin. My old laptop has a Win10 system and I used a partition tool to create a Linux volume. The installation process is stuck at the part when you choose where to install Zorin.

What requirements must the destination have to accept the install? This is what I expected to use:

Dev: /Dev/SDA7

Type: Ext4

Size: 217354MB

Used: 16384MB

System: Linux 20.2UMA(20.2)

Is the formatting wrong?
