A few years a go a friend of mine help me set up a partition on my MacBook air to allow me to run Windows 8.
About a year ago I decided I didn't want it anymore, and with the help of the internet, I tried but mangled the uninstallation. I thought I had uninstalled it but didn't see any improvement in space on the Mac side of things.
I thought I had issues because when I started up my laptop, I was still getting the windows start up (albeit broken beyond repair.) I now believe that this is just leftover files trying to boot what's already there.
Is it safe for me to try to expand the partition back to it's original size? I can move the line with no issues. Do I risk losing data?
