I am using Windows 7 on my Sony Vaio and I have installed Ubuntu 11.04 just to test it out (I opted for installation like a program, not full installation). I uninstalled it (Ubuntu) and all of the files have been deleted, but when I start my system it still asks me whether I want to start Windows or Ubuntu.
When I try to start Ubuntu it shows me a clear message that I have uninstalled it. What should I do to remove the option to start Ubuntu on system startup? Please help! Thanks.
