I have dual boot Windows 10 and Ubuntu 14.04.5 LTS in two partitions in a ssd.

Everything works fine, GRUB appears and I can decide which OS to boot.

However, I have an error when shut downing Ubuntu. It proceeds to shut down the laptop, but it freezes in the shutdown screen. And finally being forced to shut it down the hard way.

I have tried some options like the nomodeset or the acpi force in the /etc/default/grub file. Nevertheless it doesn't shut down.

What more can I try to solve it?

Edit:

I have this output. It freezes in # Will now halt, but it doesn't.

Sorry for bad quality.

I have been experiencing the same incomplete shutdown:

Will now halt
reboot: System halted

After trying all sorts of suggestions, I have commented out the following line in /etc/default/grub, run update-grub and everything returned back to normality:

GRUB_CMDLINE_LINUX="acpi=off noapic nolapic nomodeset"

I have no idea how and why it has surfaced there in the first place though.

Add the command acpi=off to your grub boot. That may or may not work.

As an FYI, this is an acpi error- the "Will now halt", and then the corresponding freeze, means that your computer has completely shut off the CPU and other components. You can safely shut the power down- holding the power button shouldn't result in power loss.

TL;DR- It's perfectly fine to shut down the computer by holding the power button

Also, consider upgrading to 16.04.
