I am about to install ubuntu to dual-boot on my pre-installed windows 8 laptop. Before I do, I really need to know how to uninstall ubuntu safely if I don't like it, or if I have to for some reason. I've been searching for an answer to this, but I do not have any sort of windows 8 disc. At all. This laptop came with windows 8, and I have no way to repair anything or things like that.
So how would I go about uninstalling Grub and Ubuntu completely from my computer and restore the windows 8 boot manager with the circumstances that I'm in? I cannot find any solution except booting into the installation CD and repairing things – which I don't have.
