When you you buy a new laptop (or PC) without operating system, it is very possible that its hard disk may not be formatted. During the process of Installation Windows 11 You must create at least the partition on which the operating system will be installed. After the installation is completed, many users are facing a problem. Some hard drive partitions do not appear in This PC and are not available. Hard Disk partition not showing in Windows 11.
We take the scenario in which you have a 512 GB Hard Disk laptop (SSD). While installing Windows 11 you allocated 195 – 200 GB for system partition (Windows), and with the rest of the space available on hard drive you have created a partition of about 280 GB. The problem is that this dedicated partition for data does not appear after the completion of installation Windows 11. In this PC only the partition with the operating system appears.

Fix Hard Disk partition not showing in Windows 11 This PC Volumes
Microsoft has introduced in Windows 11 a very good system for the management of hard disks, volumes and partitions. A true partition manager of which I did not have part of the older versions of Windows.
