There is an issue with the Radeon HD 6xxx series.

press F6 when grub menu appear. Select nomodeset. Esc.

It will temporarily stop KMS support which try to detect appropriate driver for your graphics card. Now ubuntu will open in VGA mode. To fix the issue permanently : Edit /etc/default/grub

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

replace the line with

GRUB_CMDLINE_LINUX_DEFAULT="radeon.modeset=1"

If it failed to fix the problem then edit the line too. but check first before apply this step.

GRUB_CMDLINE_LINUX="nomodeset"
