Error: [0.000000] tsc: Fast TSC calibration failed

I am trying to install ubuntu 14.0.4.2 . When I enter the startup of the installation process, it stops at [ 0.000000] tsc: Fast TSC calibration failed and even after a millennium of CPU cycles nothing happens.

What should I do or what am I doing wrong?

P.S.: I have read other similar questions on Superuser or StackOverflow but they all suggest that the error is not serious and that it should go away after a while, but it simply does not.

Try this:

Open a terminal,

Press Ctrl+Alt+T

Run it:

sudo -i
nano /etc/default/grub

In the file that opens add to the line that reads:

GRUB_CMDLINE_LINUX_DEFAULT="?????????????"

Which following

clocksource=acpi_pm

To be well:

GRUB_CMDLINE_LINUX_DEFAULT="?????????????clocksource=acpi_pm"

Ctrl + U, paste.Ctrl + O, save file. Ctrl + X, close nano.

Then run:

update-grub
reboot
