Case: I'm using Windows 7, and recently I found it runs more and more slowly. After asking help on the internet, with disk map attached, I was suggested to enlarge the boot partition with system built-in disk management tool to solve the problem. Nevertheless, though I did as told, I still can't extend boot partition since the function "Extend Volume…" is inactive, like the following interface shows:
What's the reason?
Can't Extend Boot Partition with Snap-in Disk Management
There are 2 possible reasons. Firstly, the boot partition which needs expanding is FAT partition. Secondly, there is no unallocated space behind and neighboring to the partition we want to extend. Well then, is there a good way to realize partition extending under these situations? Currently, excellent third-party partition manager can help extend any formats of partition successfully as long as there is unused space on hard disk (unused space from existing partitions and unallocated space is available). MiniTool Partition Wizard is such a partition manager. Next, let's use this program to deal with the problem that Windows built-in disk management tool can't extend boot partition.
Extend Boot Partition by Using MiniTool Partition Wizard
Next, select the boot partition (here, boot partition is system partition, namely partition C) and click the function "Extend Partition" from action panel to get the following interface:
Now, choose a partition or unallocated space to take free space from, and then drag sliding button boxed with red line to decide how much free space to take. At last, click "Apply" button in the main interface to apply all pending operations to computer. After application, we can say boot partition has been extended.
If your Windows built-in Disk Management tool also can't extend boot partition, now, turn to the partition manager MiniTool Partition Wizard. It would not disappoint any of you.
