When you try to extend a volume in Disk Management, the Extend Volume option may be grayed out even though there is unallocated space on the disk.<\/p>\n

 <\/p>\n

\"extend
Example 2: Extend Volume grayed out<\/figcaption><\/figure>\n

 <\/p>\n

Cause<\/h2>\n

In screenshot 1 above, the Extend option is grayed out because a partition (i.e., Recovery) appears between C: and the Unallocated space. Disk Management doesn’t let you extend a partition if the free space is not adjacent<\/strong> to the volume. Importantly, the free space must be on the immediate right<\/strong> side of the drive you plan to extend.<\/p>\n

In screenshot 2, the Extend option is grayed out because the free space exists inside the Extended partition.<\/p>\n

Resolution<\/h2>\n

Given the above situation, here are your options to extend the volume:<\/p>\n

In Example #1 above, as the “Recovery” partition appears between C: and the unallocated space, disable Windows Recovery Environment using ReAgentC.exe.<\/p>\n

Then, use Diskpart to delete the Recovery partition. Extend C: by occupying the unallocated space (minus 750 MB for the Recovery partition). Then, create a Recovery partition at the end of the disk and re-enable WinRE<\/a>.<\/p>\n

Alternatively, you can use a third-party tool like NIUBI Partition Editor or AOMEI to extend C into the non-contiguous unallocated space.<\/p>\n

\n

In Example #2 above, you can see that the “Free space” segment is inside the Extended partition (shown in a dark green outline). When a logical partition is deleted, it becomes “Free space” (which is different from “unallocated space”).<\/p>\n

Note:<\/strong> To merge the logical partition into the primary partition, you must<\/strong> delete all<\/strong> logical drives and then delete the extended partition. This creates an “unallocated” space. You can now extend a primary partition into the unallocated space if the unallocated space is located adjacent<\/strong> to the primary partition.<\/em><\/p>\n

In this case, there is only one logical drive that has been deleted already, resulting in “Free space”. You only need to right-click on the free space and choose Delete Volume from the context menu. The space will become unallocated, and you should be able to extend the C: drive.<\/p>\n","protected":false},"excerpt":{"rendered":"
