How To Open Hidden System Reserved Partition In Windows 7


Users who have performed a clean install of Windows 7 on a empty or new hard disk would know that Windows 7 setup creates a 100 MB reserved partition before installing Windows 7 on a new hard disk. The partition contains boot files and Windows Recovery Environment files, and doesn’t allow you delete this partition, as doing so may prevent users from booting into Windows.

By default, Windows 7 hides this special partition in Windows Explorer. To check if there is a system reserved partition on your Windows 7 PC, type diskmgmt.msc in Start menu search box and hit enter key. This will open Windows Disk Management, where you can see the system reserved partition.
