My computer is currently using Windows 7 on my main HD which is 500GB and I have a storage HD which is 290 GB which is partitioned into two 148GB drives. When Ubuntu installed, it put itself on my storage drive (H) and partitioned it, I didn't know what drive it was using and realized what was going on after wondering why it wasn't booting or recognizing I had Ubuntu installed at all.
My problem is this: I want to allocate 60 GB of data partitioned for Ubuntu 12.10, and around 100-150 GB for Windows and I wish to separate my games to another 200-300 GB partition and use another smaller one for other photos, programs, etc.
How would I best go about doing all of this without screwing anything up, losing any data and keeping everything neat and organized like I want?
I appreciate any help, and if this is in the wrong section, I apologize.
EDIT: To include some more information, I'm using Disk Manager to delete the partition Ubuntu made on my spare HD and it's now just 'free space'. I haven't completely deleted the partition because of the error message (I googled it and I 'kind of' grasp what it means), as for my main C: drive that is 500 GB, I want to partition that off into 150/60/remainder for Windows 7/Ubuntu respectively. It has 306.07GB of free space, I'm not sure if any of this helps but it does raise the question: How can I safely separate the Windows 7 data from all of my games/programs when I partition it off?
