Double click on the System Reserved Partition and you should now be able to extend the partition size. Because the boot loader files are stored on it, Windows wont boot properly if you delete this. Now you should see some Unallocated space. You cant just delete the System Reserved partition, though. Then drag the handle to the partition size you desire when the mouse pointer changes to a double-headed arrow and click OK.Īfter previewing the changes, just click Apply and you will successfully resize a Windows 7 partition.
