Too many entries in GRUB

[telovin]

Hi,
I have so many entries in GRUB and have to actually scroll down so much to see windows entry. How do I remove unwanted entries in GRUB? Also How can I make a background picture appear when grub manager comes up?Kindly help.

I use Ubuntu-Tweak for that. Among some really great functions, it has a Kernel Purge function in the package cleaner section. I recommend this. Open terminal and do:

sudo add-apt-repository ppa:tualatrix/ppa
sudo apt-get update && sudo apt-get install ubuntu-tweak

Just so you know, it's a good idea to keep at least 2 kernels in case of problems with one of them.

To add pictures, try installing Grub Customizer from synaptic package manager, it may be in software center too, not sure.

If you don't want to remove them with Ubuntu Tweak, open synaptic and search for "image-2" and remove any kernels you don't want. Careful not to remove the wrong one.

Grub customizer is in the Ubuntu software Centre. You will need to search for grub-customizer. Otherwise you may not find it. You can also install some splash images. Search for grub-splashimages. They get put in usr/share/images/grub. You need to know the location so that you can use Grub Customizer to browse to the image file you want.

I recommend Grub Customizer. If you install more than one version of Ubuntu, as I have, and the new installation overwrites the Grub boot loader so that you no longer have the splash screen, as this recently happened to me, then Grub customizer has an option to install Grub in the MBR. And once again you will be using the Grub from your main Ubuntu.

Regards.

Hi,
When I open grub customizer, I am getting the following error messages.
"grub-mkconfig couldn't be executed. You must run this as root"
I try to right click to look for an option to run as root, but no. What is the command to run this as root?
(I have actually used grub customizer before,but now when I try to use it I am getting the above error message. I forgot how I used it with admin privileges)

Hopefully you can find something in here to help.
If not, drs305 does answer questions in there also.
HOWTO: Grub Customizer

I used ubuntu tweak,deleted some entries, but was showing error

"E: linux-image-2.6.31-20-generic: subprocess installed post-removal script returned error exit status 1
E: linux-image-2.6.32-23-generic: subprocess installed post-removal script returned error exit status 1"

I could delete some entries from tweak and in ubuntu tweak its showing only four entries now. I did sudo update-grub. Got the following error when I tried updating grub.

Generating grub.cfg ...

Restarted the system. But my grub manager was still showing too many entries. It looks as if nothing got deleted. I tried to apply a back ground image, even that did not come.

I'll try grub customizer now.

I tried via synaptic, even synaptic showed the same errors.

I cant do anything with grub customizer. When I open it, it gives the following error
I open GC, it asks for password, I enter my admin password, it runs and again shows me the error message.
When I type sudo gksu grub-customizer from terminal then also I get the following error.

"grub-mkconfig couldn't be executed successfully. You must run this as root!

Thought "sudo' is for running as root.

I also tried the follwoing commands on terminal

sudo cp -R /etc/grub.d/ /root/Desktop
sudo apt-get update (I couldn't install it, it was showing errors.)
sudo apt-get purge grub-common 
sudo apt-get install grub-pc

When I typed sudo apt-get purge grub-common, I got the following errors.

(Got error messages:dpkg: error processing linux-image-2.6.32-27-generic (--remove):

When I type the last command "sudo apt-get install grub-pc"

I get the following errors. I am copy pasting only the error part from my terminal.The whole thing is too long.

I have 10-12 (or more don't know exactly) entries on grub. It is my parents who use this pc, so I want to make it simpler for them before I go. Kindly help.

Why not use Synaptic or apt-get to remove kernels you don't need? In Synaptic, search for "linux-image" and mark the ones you don't want for removal.

That was recommended in post-#3, see post-#7. Synaptic is giving errors. This is a whole new problem. Maybe it would be a good idea to start a new thread on that, if you can't find an answer via google or the search bar in this forum.
