Hi, thanks for using JustAnswer to solve your problems.
Well, unfortunately you can not resize or move to another hard drive GB, if not from a formatting system, where you can tell how you want your partitions. Once they are already created, you can not offer more or less space to another partition. You will have to proceed to format the system to decide how you want to distribute GB. That if, before you format, you have to save all data (files, music, pictures, text, etc.).. The programs can not recover, you need to download and install. Anyway, if you get stuck at some point, can you tell me and I without any problem I will try to solve. I await further developments. A hug! If you've clarified your question can you accept the answer, once satisfied, according to the commitment to quality site, all without prejudice to try to solve any questions later about it.
