I installed Ubuntu 12.10 alongside Windows 7 in a different partition. Then I formatted the partition where Windows 7 was installed.Now i want my grub menu to display only Ubuntu for Booting. But it is also showing Windows 7. Is there any way I can clean Grub Menu to Display Ubuntu Only not windows ??
Open a terminal (Ctrl+Alt+T) and run:
It will not find the Windows partition and will remove its entry from the Grub menu.
