Ok, I've searched all over every forum I can think of and I can't find anything anywhere. I apologize if this has been answered on this site; I couldn't find it. My C: drive has been displaying a size of around 60 gb with 40 free even though it's a 300 gb drive. I thought the issue would resolve with a clean install, so I did that. Now I have a fresh install and i need to reinstall everything, but the problem isn't fixed. Below are some screen shots of the drive size: This is the size Windows is showing ^ Disk Management, showing my C: Drive's full size ^ Any suggestions of how I can reclaim this space?? I've tried a few things already to no avail. If you need any more information about my computer to help, let me know. This is pretty annoying, 'cause I want to use that extra space to install Ubuntu. Oh, I just remembered. When I look at the drive in Paragon Partition Manager, it shows the full Drive size, but says that the space that is missing from Windows is in use.... I have no idea how this happened.
