Open Disk Management in Windows 7
You want to use Windows 7’s Disk Management utility to edit your partitions but you don’t find it. Where the hell is it?
Click on Start and in the search field type in the following: diskmgmt.msc, then press Enter. Disk Management will start.
Or, open a DOS shell and launch
Create a folder on your desktop called System, and place a shortcut on
diskmgmt.msc in it. This way Disk Management will be easily accessible.
