editing the Grub2 file

[gilloz]

I presently dual boot with Vista Home Premium and Ubuntu 10.04 LTS. Since the installation of Ubuntu about 8 months ago, my Grub menu at boot up shows all the updates for Ubuntu 2.6.32-24, -25 and -26. How can I eliminate the first two and only leave the latest update? The Grub2 menu is getting bigger each time.

Install startup manager,

sudo apt-get install startupmanagerYou can find it under System>>Administration>>

In the second screenshot you can select how many kernels to show.Just keep it on 1.

Thanks karthick87 for your response. My Startup Manager does not look like yours. There are no Appearance or Security tabs in mine. Under the Advance tab, I only have Boot Menu Resolution and Create Floppy. Nothing else. Now what?

Install ubuntu-tweak,and clean your old kernels,

Hi

This might be interesting as well. I have never used it so....


Grub Customizer is a new graphical GRUB2 settings manager. For now, it only allows you to edit the GRUB2 menu entries: reorder, rename or add/remove entries. Since these are actually scripts which generate the boot.cfg file, Grub Customizer changes the actual script order and then generates a new boot.cfg so if you then run "sudo update-grub", your customization won't be overwritten.

If you try it post back your impressions.

Kind regards

OK. Tried that and no packages are listed.

edit grub.cfg

make a backup first

sudo cp /boot/grub/grub.cgf /boot/grub/grub.cgf.backup

sudo nano /boot/grub/grub.cgf

look for menuentry and comment them out i.e:

#menuentry 'Ubuntu, with Linux 2.6.35-23-generic (recovery mode)' --class ubuntu --class gnu-linux --class gnu --class os {
# recordfail
# insmod part_msdos
# insmod ext2
# set root='(hd0,msdos1)'
# search --no-floppy --fs-uuid --set e1791282-9347-4c24-8bfb-be54309d1159
# echo 'Loading Linux 2.6.35-23-generic ...'
# linux /vmlinuz-2.6.35-23-generic root=UUID=68081c72-09eb-446b-b536-b00e2e61eedf ro single
# echo 'Loading initial ramdisk ...'
# initrd /initrd.img-2.6.35-23-generic
#}

Installed Grub Customizer with no problem. However, the "Remove" option is grayed out when I highlight one of the entries.

You can go into synaptic package manager and enter the kernel numbers into the search box. Mark them for complete removal and apply the changes. There will be 2 entries at least for each kernel.

If you edit grub.cfg your changes will be over-written when grub is updated.

Hi


If you edit grub.cfg your changes will be over-written when grub is updated.Very true. Any kernel update or grub update will revert the changes. Any time you need to manually update grub will also overwrite the changes.

Can i make a suggestion? I would keep the last two kernels in case you have a problem. You can then boot into the older kernel.

Kind regards

I want to thank everyone for coming to my rescue. I finally modified the Grub2 menu by doing what I was suppose to do several responses ago. When I opened my Ubuntu-Tweak, and clicked on Package Cleaner, I then went to the Right side and clicked on Clean Packages instead of Clean Kernels. That is why nothing was being listed. After reading post from matt_symes and went to the link, that is where I realized my error. I followed through with the instructions shown in the link and I was able to clear my Grub2 menu less one earlier Kernel. All is good now, thank you all.

Added Note: Karthick87's post had the image that would have solved my problem at the start. I just missed it. I really appreciate everyone's comments and inputs.
