I have installed Windows 7 and Ubuntu 11.10 on my PC and Ubuntu was installed using WUBI installer.
Today, I format my PC and installed Windows 7 and after restarting the PC, there is still displayed a dual-boot (Win 7 and Ubuntu) menu, but I do not have install Ubuntu.
Can anyone tell me what is wrong and why is there still a dual-boot screen? How can remove this dual boot and install new version Ubuntu along Windows 7? Can anyone help me with this?
