Ubuntu – How to prevent one of the partitions messing with Lubuntu Grub entries

bootdual-bootgrub2lubuntupartitioning

I recently deleted my Windows XP partition in my dual boot machine (Lubuntu/Windows XP), replacing it with Bhodi Linux. Everything went smoothly, but now I have a problem: Bodhi Linux is messing with my Lubuntu Grub entries, and every time I update something of significance there, Grub ends looking like this:

Is there a way to prevent this? I know how to edit Grub entries, but it seems like quite an annoyance have to do this with every update.

(Yesterday I updated Lubuntu from 13.10 to 14.04 and that seemed to fix the issue. But later on I updated Bodhi Linux and there it was again)

Do not know Bodhi, but with Ubuntu.

To see what drive grub2 uses see this line - grub-pc/install_devices:

sudo debconf-show grub-pc
sudo grub-probe -t device /boot/grub

to get grub2 to remember where to reinstall on updates:

sudo dpkg-reconfigure grub-pc

Enter thru first pages,spacebar to choose/unchoose drive, enter to accept, do not choose partitions If Bodhi works the same, do it first and unchoose everything. Then it will not reinstall. Boot into Lubuntu and run it to make Lubuntu install to sda and be the system to boot by default.

Ubuntu – How to edit grub for many entries of previous kernels with multiple ubuntu installations

I'm guessing that the "Previous Linux versions" submenu isn't being created because of all the different boot points that you have. But you should be able to add it with the Grub Customizer:

sudo add-apt-repository ppa:danielrichter2007/grub-customizer
sudo apt-get update
sudo apt-get install grub-customizer

Once you have that installed and running, you can manually create the "Previous Linux versions" submenu. I don't know if future runs of grub-update will respect that setting with regards to managing newer kernel versions, but it should at least help you to better manage this issue.

This is a tough diagnosis problem. Some more info would help, as listed below.

In the meantime, and as listed in the sources below for related (although not exactly the same) problem, you could try these alternatives, perhaps in combination:

Reduce the timeout for booting to 1.
Set Recovery Mode as the default boot option.
Avoid the splash boot loader, using GRUB_CMDLINE_LINUX_DEFAULT="". See How do I disable the boot splash screen, and only show kernel and boot text instead?
Use nomodeset in the boot option in Grub. You could set it permanent for a while with GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset". See also How do I set 'nomodeset' after I've already installed Ubuntu?
Force booting from a LiveCD by setting the boot order and/or disabling the HD. This will give you a system where you can perform tests.
Force booting from an external HD by setting the boot order and/or disabling the internal HD. This will give you a system where you can perform tests. YMMV depending on what you have in the external HD.
Try determining if you have the correct graphic drivers. This is an unlikely source of error, as the problem is with Grub...

Useful additional info:

What do you mean by "bootlooping"? Your description looks more like a boot freeze.
Monitor brand, model, resolution.
PC model and OS of your old Lenovo that was working fine with your monitor.
Did it have Grub?
Are you willing you install Grub on that old PC as a means of testing?
Connector you were using with the Lenovo.
Do monitor&Dell have another connection that may be tried?
Do you have another monitor or TV that you can try with your Dell?
