Accessing Disk Management
There are a few different ways to access Disk Management. I'll list three different methods so choose whichever is more convenient.
Method 1 - Start > Control Panel > Performance and Maintenance > Administrative Tools. Double click Computer Management and then click Disk Management in the left hand column.
Method 2 - By default, Administrative Tools is not shown on the Start Menu but if you have modified the Start Menu (by right clicking the Start button and selecting Properties > Customize) so it is shown then just select Start > Administrative Tools > Computer Management and then click Disk Management in the left hand column.
Method 3 - Click Start > Run and type diskmgmt.msc in the Open: line and click OK. The Disk Management snap-in will open.
