Precise GRUB create several entries of previous versions after installed

[Jorge Antonio Dias Romero]

I had the following partitions in my HDD

/dev/sda1 -> Windows
/dev/sda5 -> Oneiric
/dev/sda6 -> Swap

I resize (shrink) the windows partition with Gparted and installed Precise Beta in a new partition /dev/sda3 (see fdisk -l attached).

After the installation of Precise, the GRUB loads and works normally, but several entries appears. I attached a screenshot of the grub screen.

I have only 3 systems, but the Grub screen have 4 entries for "Ubuntu, with Linux with 3.0.0.X" : 3.0.0.16-generic, 3.0.0.15-generic, 3.0.0.14-generic and 3.0.0.12-generic). All them opens Oneiric (see atacched screenshot for better understanding)

I tried run the command update-grub, but nothing change.

-What you expected to happen

I expect to have one entry for each system.

-What actually happened

After Precise installation, several entries appeared, all them related with the Ubuntu Linux 3.0.0.X.

This is normal. When you have multiple installations of Ubuntu, they are all added to the grub menu.

Thanks Phillip. After a deeper research, i found that grub creates, by default, entries for all older kernel images , so it's really not a bug. It's the normal behaviour of grub.

To keep the Grub screen less "polluted" i used a program called "grub-customizer", to remove some entries, following this tutorial: http://ubuntuforums.org/showthread.php?t=1664134. This tip, may be useful for those who want remove some entries from the initial screen without delete the kernel images.
