2. Click on Apps, and search for Computer.
3. Right click on Computer and you would notice a pop up on the bottom right of the screen. Click Manage.
4. Click Disk Management form the left pane and if you have installed a new HDD, you would be prompted by a message to initiate it with a check on the newly installed HDD. Just click OK.
