I have a Dell T5810 running Ubuntu 16.04 LTS. On Friday 9th Feb a software update failed and ended in the GNU GRUB menu.
If I select boot it tells me I need to load the kernel first. If I select exit, it tells me there are no bootable devices.
I have done a full hardware test and it has passed.
Is is possible to boot from this situation without losing the contents of the disc? If so how?
Yours,

Thanks for looking at this Karel. The GRUB menu is really basic, about fifty different commands, most of which I don't understand. "Advanced options for Ubuntu" isn't one of them.

Reboot or cold start the computer.
Immediately after the BIOS/UEFI splash screen during boot, with BIOS, quickly press and hold the Shift key, which will bring up the GNU GRUB menu. (If you see the Ubuntu logo, you've missed the point where you can enter the GRUB menu.) With UEFI press (perhaps several times) the Esc key to get to the GRUB menu. Sometimes the manufacturer's splash screen is a part of the Windows bootloader, so when you power up the machine it goes straight to the GRUB screen, and then pressing Shift is unnecessary.
From the purple GRUB screen select Advanced options for Ubuntu with the ↑ and ↓ keys and press Enter.
A new purple screen will appear showing a list of kernels. Select an older kernel version instead of the latest kernel version and press Enter.
Ubuntu will load the selected kernel and proceed to the login screen as usual.
After rebooting
Find the latest installed kernel version in the results of the following command:
dpkg -l | grep "linux-[a-z]*-"
Uninstall the latest kernel.
sudo apt purge <latest-kernel-version-number>
Replace
<latest-kernel-version-number>in the above command with the latest kernel version number.
Update grub.
sudo update-grub
Reboot.
sudo reboot
Don't let Ubuntu update the kernel to the kernel version that caused the GRUB menu boot problem again, or else you'll get the same problem that you got before. Instead wait for the next kernel update and update to that kernel version.
