Are you new to Linux? Why did you expect it to be mounted?

Seems like an unmounted usb-installation media to me. Did you leave your usb stick on your pc after installation?

yes, iā€™m new to linux. And i actually made it made it a bootable usb using dd. After using it i tried to format it. and this happened.

For formatting a device, it needs to be unmounted anyways.
