Ubuntu – How to disable Grub’s menu from showing up after failed boot

I know you posted this back in May, but I found some stuff that might help anyone looking at this article. I have the same exact problem, and I have not found a true fix for my symptoms yet, but I figured I would post some of my findings.

First, the trick with running some apt-get updates can be found here:link.

I modified mine a bit based on some other articles I read, and also because I encountered one error message with the cp command while trying to copy:

(This is assuming you did the first two steps from the link above and are running from a Live CD that you booted from)

sudo mkdir /media/precise
sudo mkdir /media/precise/proc /media/precise/dev /media/precise/etc
sudo mount /dev/sda1 /media/precise
sudo mount -o bind /proc /media/precise/proc
sudo mount -o bind /dev /media/precise/dev/
sudo mount -o bind /dev/pts /media/precise/dev/pts
sudo cp --remove-destination /etc/resolv.conf /media/precise/etc/resolv.conf
sudo chroot /media/precise apt-get update
sudo chroot /media/precise apt-get upgrade
sudo chroot /media/precise apt-get update --fix-missing
sudo chroot /media/precise dpkg --configure -a
sudo chroot /media/precise dpkg-reconfigure keyboard-configuration
sudo chroot /media/precise apt-get -f install

The reason I had to add the --remove-destination is because I was getting an error message that read something to the effect of: cp: not writing through dangling symlink path/to/danling/symlink/a-file (found the solution for that here: force cp to copy on dangling symlinks)

Secondly, it wasn't until the OS booted that the problem presented itself (hence why the Live Disk worked just fine). So, choosing different option in Grub was possible. I had gone back by two kernels and still had the problem.

Finally, while working on it with someone else at work, he had looked the computer the day before, and said that he booted back several kernels and got into command line, but not GUI. This was a great start because I had an Apache Web Server I needed to get up and available for people again ASAP. So, right now, the machine is running on an old kernel with a broken GUI but apparently working CLI and I am not sure what to do next. Try to remove the kernel? Remove and reinstall X? Not totally sure, but at least its a start, and maybe the link and code I listed above will be a fix for someone else with this problem.

Windows 10 Anniversary Update, and the more recent Windows 10 Creators Update, have a really bad habit of wiping out Linux partitions on MBR disks. Sounds like you're a victim.

Recovery is possible, but it can be tricky.

Boot to the Ubuntu Live DVD/USB.

Open Software & Updates and make sure that all of your software repositories are enabled.

In terminal...

sudo apt-get update # update the software database
sudo apt-get install testdisk # install testdisk
man testdisk # read the manual
sudo testdisk # start testdisk

Update:

Your missing Ubuntu partitions were between partitions 4 and 5, and went from 1015GB to 1983GB-1.
