I have a problem: I have Windows 7 installed on my notebook. I wanted to install ubuntu on it. So I did. Then I removed Ubuntu because of several lags. And when I rebooted, it still showed Ubuntu in the list of opSystems. So I thought, that reinstalling ubuntu will fix this problem. So I did. And now it shows: Windows 7; Ubuntu; Ubuntu. And when I try to boot into first (old) Ubuntu, it shows an error (because there is no such an operating system installed). The second ubuntu runs well. I just want to delete this uld ubuntu from the list. I tried to do this with synaptics, but it did not help.

Are these Ubuntu WUBI install or installed via booting a live CD/USB? Please edit your question to add information. – user68186 Oct 9 '12 at 16:27
