Ubuntu Shows Up Twice in GRUB

[Unanimated]

Okay, here's what I've done with Ubuntu that has led me to the problem at hand.

1. I booted up the live CD to see what it was like.
2. I installed Ubuntu as part of the desktop, again to see what it was like at full(ish) speed.
3. I decided that I wanted Ubuntu as my main system, so I did a full installation that took over my D:\ drive.
4. When I was setting up my speakers and Internet connection in the full installation, I thought I was done and checked for updates. U crashed.
5. I rebooted my computer and opened Ubuntu again and signed in.
6. My mouse and a blank desktop was shown. After a long time, my background finally loaded. After a longer time, the white bars at the top and bottom of the screen loaded, but nothing showed up.
7. The next day, I put the CD in again and did another full installation. I chose to use the full D:\ drive for the installation.
8. Now, when I start GRUB, Ubuntu and Ubuntu recovery mode show up twice, but the memtest shows up once. Windows still shows up once.

I guess what I'm really wondering is how I can get rid of the other Ubuntu that I'm not using without getting rid of the one I am. This wouldn't be an issue if an unneeded 10 GB of my hard drive was being taken up, which is a problem. If it involves the terminal, please put the code that I need to input. Thanks!

sudo fdisk -lu

Thanks, but what was that supposed to do? It gave me a list and I don't know what to do with it.

Copy and paste here.

paste the output of that command into a post, preferably in a code block. It helps diagnosing any problems.

You have Linux installed in sdb1, sdb2 and sdb5 (/swap) There are no other instances of Ubuntu. Give details about your Grub Menu.

[Ekeluo]

You need to edit ur menu.lst(/boot/grub/menu.lst) (as root, i.e. gksu, or sudo from terminal) and remove invalid entries after consulting the above list.

P.s. Doesn't update-grub do this?

Well, I turn on my computer and it boots from the disk drives. After that, it says GRUB Loading. Then, it bring up a list that looks like this, only it has a bunch of numbers at the end of Ubuntu that I can't remember and so I'm just not going to put them.

Ubuntu
Ubuntu (recovery mode)
Ubuntu
Ubuntu (recovery mode)
Ubuntu memtest+

EDIT: This is what it says in the menu file:

I just did that, and it looks exactly the same.

Its just you have two kernels installed, nothing to worry about!
Ubuntu always keeps the last kernel incase you have problems with the latest upgrades...

I dont think your first (and faulty) ubuntu install is showing up in grub!

[housam]

looking at your file.lst, you've updated your system from kernel 16 to kernel 19.
you can remove the unwanted kernel from the grub menu by adding the # in front of each line related to that kernel. then save and reboot.
as an example :

#title Ubuntu 8.04, kernel 2.6.24-16-generic
#root (hd1,0)
#kernel /boot/vmlinuz-2.6.24-16-generic root=UUID=00213b73-c880-4f4e-82dc-493ac67556d3 ro quiet splash
#initrd /boot/initrd.img-2.6.24-16-generic
#quiet

Does that mean that I can open the menu file and just remove the last two Ubuntu (not memtest) from the list and it will be fine?

[Pumalite]

You are not removing them. You are just preventing them from showing up in your Grub Menu. Is good to have another kernel to boot from in case of trouble.

as an example :
When I do that, I click save and it says that I do not have permission to save it. Do I need to be on a certain account to be able to save it?

[housam]

edit the menu.lst using this code

gksudo gedit /boot/grub/menu.lst

[Pumalite]

gksudo gedit /boot/grub/menu.lst
Make changes
File>Save
Exit

It works just fine now. Thanks everyone!

Well ur problem's solved, wanted to make a suggestion - startupmanager (available in repos) can automatically restrict the number of kernel that show up in grub along with several other nice tweaks it handles.It has a gui so no problem using it, give it a spin. Also you might want t periodically remove i.e. uninstall older kernels if you find the newest one works alright for you. Might save you a few mbs (~80 or so).

How do I remove the other kernels?
