So basically the issue I'm having is that I attempted to install Linux Ubuntu on a separate partition of my SSD, which I set to 8GB, however, for some reason it chose to overwrite my windows 7 partition. In attempt to make things better, it appears I have dug myself a bigger whole and no longer have any OS on it. I have access to another computer which I used to try recover important files before I completely wipe it. However, when I looked in Disk Management it only displays 220GB or so - completely missing the files which I had previously on my windows partition. Is there any way to recover these missing files? Or are they lost forever?
