Extend System Partition Windows 7 64 bit

Extend System Partition in Windows 7 64 bit using snap in Disk management has many limitations, you cannot keep data intact when extend volume gray out in system partition, so we'll fix this problem listed with Partition Extender:

1. Windows 7 extend system partition greyed out
2. Windows 7 cannot extend system partition

Windows 7 extend system partition greyed out

When you run disk management to extend system partition, Extend Volume from the right-click menu greyed out, now please check if there's any unallocated space behind system drive, unallocated space is space not partitioned, not assigned drive letter, marked as "star" in disk management. If it is Partition D or E followed instead of unallocated space, Extend Volume option will be grayed out.

Solutions to solve Extend Volume gray out problem is to make some unallocated space to the right side of system partition, so we can make Extend Volume active again.

Steps to extend system partition when Extend Volume greyed out in Disk Management.

  • 1. Right-click D Partition, or the Partition next to C Drive, and select Delete Volume... from the menu (it's better to backup this partition to external hard drive, or other partition with free space.)
  • 2. Confirm your operation when info dialog shows;
  • 3. After Deleting, right-click C Drive /system partition and click Extend Volume, now extend volume option is clickable and active;
  • 4. Follow Extend Volume Wizard and distribute free space to extend system partition; it's recommended to leave some free space for D Partition recovery;
  • 5. Right-click the left unallocated space, select New Simple Volume... and that's to create D partition again, move your files back to D partition; done.

That's the steps to extend system partition in Windows 7 64 bit when extend volume grayed out in disk management, first delete partition to make space unallocated, and then extend volume with this space, the final step to create partition and recover data in the partition deleted before. The theory is simple, but steps are complicate.

Windows 7 cannot extend system partition

Windows 7 cannot extend system partition basically due to two reasons: Extend Volume grayed out in Disk Management (we already fixed that); Diskpart in Windows 7 cannot extend system partition. Diskpart the command line only works for other logical partition, so when you type Extend in diskpart, it'll show the following error:

There is not enough usable free space on specified disk(s) to extend the volume
