LinuxQuestions.org - atombios stuck in loop for more than 5 seconds

Hi,

I have an HP G62 laptop. Its graphical card is an ATI Mobility Radeon HD 545v. Windows 8 is the Operating System which is running on it. I have a BIOS firmware and not a UEFI.

Yesterday, I decided to install Ubuntu 14.04.3 LTS in dual boot mode with Windows 8. Therefore, I followed this tutorial :http://itsfoss.com/install-ubuntu-14...ows-8-81-uefi/. These are the steps:

Downloading the Ubuntu 14.04.3 LTS iso
Making an Ubuntu bootable USB key with Universal USB Installer
Desactivating the fastboot mode on Windows 8
Shrinking the C drive to make some free space for Ubuntu
Changing the BIOS configuration in order to boot from the Ubuntu bootable USB key

I do not have the secureboot mode because I have a BIOS and not a UEFI.

When I booted from the Ubuntu USB key, the installation screen appeared.

Then I clicked on the "Install Ubuntu" option and then the following errors started appearing:

[drm:atom_op_jump] *ERROR* atombios stuck in loop for more than 5 seconds
[drm:atom_execute_table_locked] *ERROR* atombios stuck executing E046

Could you help me please?
