How to restore USB drive back to full capacity

Recently I used an USB pen drive as a bootable drive for UBUNTU installation. However I got success installing Ubuntu in my system but a new problem arises in the USB drive. The problem is the size of the USB drive. The pen drive I used earlier has giga bytes of storage. But after I used it as bootable USB drive size reduces to MBs. If you too are facing this problem then you are at the right place. Yes, by applying some windows Command prompt tweaks I successfully restored my pen drive back to full capacity. So in this tutorial I will be showing you how to restore USB drive back to full capacity.

Initially USB drive capacity was 8 GB but after I made it a bootable USB it shows only 2.19 MB. Well I guess due to Ubuntu the USB drive’s primary partition is not loading properly.
