I have tried to open GRUB boot loader by pressing key while booting but nothing happened, screen just glows for a second and goes off. but will try this next time for sure if this happens. can u help me in that askubuntu.com/questions/772771/… If the problem(s) are in the power system there's absolutely no way to determine the viability of the software intallation.
Already tried purging & reinstall grub, but that didn't fix the problem. This will tell what is where: Boot Info Script courtesy of forum member meierfra Page with instructions and download: Paste results.txt, then highlight entire file and click on # in edit panel(code tags) to make it easier to read.
Does anyone have any ideas what's going on here or have any other suggestions I might try to get this fixed?
On Monday, I was able to edit the grub.d scripts and /etc/default/grub and run update-grub and would change accordingly and my boot menu would show the changes in Just had to run grub-setup and set it to /dev/sda and it's working again.
Today, I am trying to make changes to grub, and when I run update-grub, my file does update properly, but when I reboot, the menu entries do not change. That would explain a getting updated but you are booting a different install. I don't have a clue what would have screwed up the MBR.
At boot there was still the same stubborn list of old kernels, and the new ones were not listed.
Turns out somehow grub (v1), Ubuntu package name ‘grub’ had ended up on my system, where the config was grub2 based.
Just had to run grub-setup and set it to /dev/sda and it's working again.
So I did apt-get remove grub; apt-get install grub-pc and all was well again, including the latest and greatest kernel in the boot menu.Ubuntu 10.04 x64 Did a fresh install on Monday this week and ran updates. I don't have a clue what would have screwed up the MBR. Grub boot problem on Ubuntu 14.04 that people seem to have had for older versions too: the grub boot loader does not get updated with newly installed kernels.Did not find a solution on the net though, so here goes.
Newer kernels get installed but do not show up in the boot menu.A bit puzzling, non of update-grub, grub-install /dev/sda or adding and removing kernel packages made any difference.
