Windows 7: Unable to delete volume

Unable to delete volume

I'm trying to delete a volume so I can extend a partition. However the option to delete volume in disk management is grayed out. How do I fix this?

Here you can see I can't delete the E: partition

Hi there, you cant delete this partition because its a system partition and its marked as Active.
Just next to the E:\ partition, there is some unallocated space. You can right click on the partition you want to extend and then click Extend Volume.

I want to delete E: so I can extend C:. I basically want the whole drive to be just one partition. However I am unable to delete the E: partition. Btw E: is not marked as active.

Sorry. Yes the partition is not marked as Active but it does contain operating system files. Could you 1st extend the E: drive and use all the unallocated space to extend it? Once its extended, it must give you an option to delete the entire volume.

did you already try to login your Windows 7 DVD and during the installation, one of the step is ask about partition, and over there you can delete it.

Your E: partition is the System partition which means it contains the files needed to boot windows. Should you delete that partition, you'll need to do a Startup Repair in order to boot windows.

Startup Repair

You can try using a 3rd party utility like Partition Wizard to delete or use Diskpart. Heres how to use diskpart.
