|You have not given us a clear picture of your partitions geometry.|
Having said that, this is what I think:
1. You probably had a mixture of Primary partitions and Logical partitions within an Extended partition.
2. When you delete a primary partition, the space freed off becomes unallocated space
3. When you delete a logical partition it becomes free space within the extended partition
4. if you had more than 2 logical drives in your Extended partitions than the free space location will depend on which logical partition you deleted. It will be in the Extended partition either at one of the ends of the Extended Partition or somewhere in the middle.
You can view your partition layout graphically by using windows disk management.
To access Disk Management:
click the Windows logo
click Control Panel
click System and Security in the top left corner
under Administrative Tools, click Create and format hard disk partitions option
You will see a graphical layout of your disk and see where your unallocated space is and where your free space is. First the two have to be contiguous and second you have to convert the free space within the Extended partition to unallocated space.
Windows disk management will allow you to do this. Resize/move your logical drives so that they are all together with the free space abutting the unallocated space. Then resize the Extended partition to shrink it and exclude the free space. This will convert the free space to unallocated space.
If the other unallocated was contiguous then you will end up joining the unallocated space and the free space that you have now freed off to become unallocated space.
Hope it helps.
Do post back if you have problems.
Note there are freeware partition tools also available that can help you achieve this. One good one that comes to mind is EASEUS Partition Master which can be downloaded from:
However, if you are going to be messing with your partitions be sure to back up your valuable data just in case.
