I installed Ubuntu some time ago. I intended to install it alongside win8, but this was not an option, so I installed ubuntu instead of win8. For work reasons I need to reinstall win8, and I have recieved recovery disks from acer. The problem is that I get a promt telling me there is no space to install, so I guess I need to remove ubuntu before recovering win8. How do I remove ubuntu from my computer, leaving no OS remaining?
