Recently I briefly toyed around with Ubuntu 12.04 for a little, and after navigating my way through multiple errors I eventually found that I was unable to launch Windows as it a file missing or something along those lines. I then refreshed Windows followed by successfully removing the "Grub Loader", however I'm now finding myself unable to remove "Ubuntu" from the list of operating systems that display upon startup. I have no programs in my Programs and Features list as a result of the refresh and have so far had no luck finding a successful method at removing Ubunto elsewhere.
Could someone give me preferably simple directions (As I'm not too familiar with some of the more complicated aspects of Windows) as to how I would manually remove Ubuntu. Also from what I've read I've been told that Ubuntu alters my partitions or something along those lines? (I'm unfamiliar with what they are). If thats the case, could someone assist me in restoring those to their original state as I'm clueless at how to do it safely.
I'll also add that if it's the easiest option and I can have it confirmed that it will fix everything, I'm willing to completely Restore my PC.
