Cant edit a partition

I was installing ubuntu on this partition in and the power happened to go out with it was being formatted so I went back into gparted and wiped it but now I cant edit it in windows7. I cant expand other partitions either. The relevant options in the context menu are greyed out. How should I go about repairing this? When I try to create a new volume even with a size lower than whats available I get the error message seen in the fourth screenshot.

Thanks. :)

Take a look at this base tutorial.
To Remove Linux take look at this post:
Error 0xc0000225 on boot

On an mbr disk, you can have a maximum of 3 primary partitions and 1 extended partition (within which you can have lots of logical volumes) which you already have, hence the error.

I suggest you use a 3rd party tool like partition wizard to pull the existing logical to the left to use the unallocated space.

Partition Wizard : Use the Bootable CD
