Two Solutions to Extend System Partition in Windows 7 to Unallocated Space

No more worries about extending system partition in Windows 7 now! When trying to get more disk space while running out of space, you don't have to delete the unwanted files. It's much wiser and more convenient to extend system partition to unallocated space!

Here offers two easy and detailed ways for you to extend system partition for Windows 7.

Solution 1 - Extend System Partition with Disk Management in Windows 7

Extend system partition with the built-in "Extend and Shrink Volume" in Windows Disk Management of Windows 7.

Note: The "Extend Volume" feature only works with contiguous unallocated space! And the "Shrink Volume" can only create unallocated space behind the partition. Disk Management can not support move partition to make the unallocated space behind system partition. As a result, you have to delete the partitions which locate between system partition and unallocated space.

To begin with, backup all data on partition D to F.

Then, right click "Computer" > "Manage" > "Storage" > "Disk Management" > right click partition D > select "Delete Volume".

Delete Volume

Finally, after deleting partition D, there will be some unallocated space behind system partition. Then right click system partition and select "Extend Volume".

Limitations: As mentioned above, you can only use the "Extend Volume" feature to work with contiguous unallocated space. What's worse, you have to backup data and delete partition, which are time-consuming and risky.
