Windows 7 - 100GB of free space is unusable, not able to create new simple volume

I deleted a partition of 100GB which was Drive D
Instead of going into unallocated space, it became free space.
When I tried to create a simple volume, it gives an error that "there is not enough space on the disk for this operation"

If i try to delete it, then a warning pops up saying that it might be inaccessible on deletion and after accepting that it gives the error that not enough space.

How can I get this back?

Looks as if you already have 4 partitions - that is all you can have on mbr disk.

Disk mgmt may be incorrectly reporting the oem partitions as primary.

Did you have 5 before?

Try a 3rd party partition manager - see what it says-this one is free and can handle gpt

You already have 4 primary partitions on that disk - how are you expecting to create another one? I'm not even sure how you managed to create 5 partitions on an MBR disk in the first place .

it was a logical partition which got deleted
how can I utilize this space now?

You cannot, not without deleting another primary partition. You can only have 4 partitions on an MBR disk, which is why Windows (by default) creates the 4th partition as an Extended partition (which can contain additional logical partitions inside of it) when using Disk Management. You have 4 Primary partitions, and as such you'd have to delete another partition from that list to create another partition (and in this case, obviously you'd want to create an extended partition once you did get to that point).

i got this info on the sectors being used by the partitions
since sda4 and sda5 share some, is that the reason why i am not able to delete the partition?
or just that I have already made 4 primary drives

Did you check with Partition Wizard ?

Are you unable to delete the 95 GB partition??

It appears to be empty.

for windows 7 should i use partition wizard or partition magic?

the 95GB partition has got Ubuntu installed on it

Partition Wizard.
