I’m sure many of you might have faced this issue in your computers or might face in future.
My friend asked me where are the other partitions which were created at the time of installation? I knew what was the issue, so I performed a few steps and all hard disk partitions started showing in This PC. C: drive was visible in My Computer (This PC). I installed Windows 10 in his laptop and when we logged in, we noticed that only the system partition i.e. I removed all existing partitions and created 4 new partitions. Since most of the branded computers come with a single or two partitions, my friend requested me to remove all existing partitions and create new partitions as per his requirements. It was a new laptop and I was doing a clean installation of latest Windows 10 version. Yesterday while installing Windows 10 in my friend’s computer, I faced this issue.
