I need Help!! *Hard Disk*

Ive been playing around with my laptop recently. It has two harddrives and i installed Linux on my secondry drive. I realised i have no use for this so i deleted it.


To install it i partioned my secondry hard drive and saved it in the free space, i think i formatted the drive and now i cant merge the free space back with its hard drive.

Does anyone know how to do this?

any help would be greatly appreciated

 

this is what im talking about....
