I had my laptop pre installed with windows 7 and then I installed ubuntu, later upgraded to windows 8. That was ok. Now, I want to uninstall ubuntu 12.04 and install 12.04.3 (yes, I want to uninstall and install. I have problems with the present Ubuntu). Can I install ubuntu 12.04.3 through wubi (as I didn't get my laptop with windows 8 pre installed)? Some of my friends suggested me to install windows 7 in windows 8, then install Ubuntu in windows 7 and after that remove windows 7. Do I really need to do all this?
In either case how do I uninstall Ubuntu? There are many questions of this sort in askubuntu.com but, my system doesn't show Ubuntu as one of the programs installed and all the solutions I have seen, say to directly uninstall using control panel.
Finally, I want to have Ubuntu up and running alongside Windows 8
