Hi: i got this boot error after installing the 64 bit ubuntu in a HP desktop computer. I'd appreciate any suggestions. Thank you.
I recently had the same problem on an HP as well. I believe it is an issue with the video driver. I corrected the issue by re-installing the correct driver.
From the error message, get to the terminal by crtl+alt+f1(login/password)
Verify your video card type (prob Nvidia or ATI)
After you verify your card, just a simple
*install the needed video driver if diffrent from Nvidia.
after the install
I hope this helps!
If you have more than one external monitor plugged in, see this bug which suggests booting with one of your monitors unplugged. Worked for me.
The install went smoothly, but I got "failed to set mode CRTC:6" when booting and had to start X manually.
