Hello, I have a PC running windows and ubuntu 12.04 on a single 1 TB WD Hard Drive. My question may be simple, and I hope that it is but- I want to increase the size of the windows partition from 373.36 GB nearer to 500 GB. The ubuntu partition is somewhere around 40 or 140 GB because it is an OS I only use every once in a while. My concern is that when I look in control panel to change the partition size, it lists some 550.17 GB free. Add the 300 some to the 500 some gives almost a thousand (923.56) add the other reserve partitions and a partition of 7.88 GB ( I dont know what this one is) and that gives all the 931.51 GB of size of my drive. Is the general disk manager windows comes with unwilling/able to recognize the size of my ubuntu partition? Is there a third party partition resizer that I could use which will see everything? Thank you for the help and I will provide any information you might need.
