WOW! I seem to have opened a can of worms with what I thought to be a simple question! Lots of the preceding sounds like Greek written in English!
OT, and JFYI, that is quite common, and we have an exception to confirm the rule :
And don't worry , you didn't open (till now) any "new" can of worms, this one has been opened since a long time.
BUT, now that you have posted the relevant info, you indeed opened an (almost) new one .
I am re-attaching your image, so that other people may have a look at it without downloading the file and opening it in Word.
Textually, the situation is the following:
D: Partition1 (HP_recovery) [NTFS] 1 MB (11602 Mb free)
H: Partition2 (System) [NTFS] 1025 MB (648 Mb free)
C: Partition3 (Windows) [NTFS] 618676 MB (545528 Mb Free)
E: Partition4 (HP:Tools) [FAT32] 95702 MB (2018 Mb free)
And we have a problem.
The MBR partitioning scheme (which is what is commonly used up to Windows 7, with Windows 8+ trying to switch to GPT) only has 4 (four) partition entries (imagine them as 4 "slots").
This means that you can have ONLY up to:
a. 4 primary partitions
b. 3 primary partitions + 1 Extended (the extended partition can contain many volumes)
and since right now it seems like you have all 4 "slots" taken by 4 primary partitions you cannot have additional volumes.
This particularly can of worm, is not completely new:
but it does make things slightly more complex, and the presence of the HP_recovery and of the HP_Tools partitions may additionally mean that you are using a "peculiar" MBR code, that MUST be backed up/preserved as recreating it might be if not impossible, absurdly difficult:
So, we will need to make an even more accurate "plan" than expected.
