I have recently purchased a second-hand HP mini laptop with Windows 7 pre-installed on it. The internal hard drive has been split into two partitions; partition C (24.32 GB) containing all the Windows files, and partition D (200.66 GB) containing software and other files. Unfortunately, partition C is not big enough to run Windows smoothly, which often leads to the laptop being very slow. I am trying to extend this partition with about 8 GB in order to give Windows more room.
I do not know what the best approach for this problem is. I believe that partition D might also have some Windows files, in which case I am unable to move this partition. I have tried to Shrink partition D, but I am unable to move the unallocated space to partition C.
I have added an image of Gparted below.
How can I add the unallocated space to partition C without damaging Windows? (I do not possess the Windows installation DVD)
Thank you for your help.
