Recently I installed Ubuntu using Wubi on my desktop. I already had Windows XP and Linux Mint in dual-boot, with the Grub Menu presenting the entries for both OS. Now that I've installed Ubuntu using Wubi, the original Grub Menu is intact, which was expected, because Wubi makes an entry on Windows boot menu. So I choose Windows XP from the original Grub Menu, then it displays the Windows boot menu, featuring Windows XP and Ubuntu. If I choose Windows XP, Windows is loaded, however if I choose Ubuntu, yet another Grub Menu comes up, with all three options there - Windows XP, Linux Mint and Ubuntu.
This is a bit unnecessary and redundant. Originally, I was expecting to have the original Grub and then Windows Boot Menu, now that there is a second Grub, I am afraid I might have some boot problem when I uninstall Ubuntu from Windows. How should I proceed to keep only one of the Grub menus, without compromising the possibility to boot into any of the OS?
