Ubuntu 10.04 will not install: cannot get past five red dots

[Boris and Bailey]

Hi. I cannot install the newest Ubuntu, 64 or 32-bit. On the amd release, the intro with the five red dots appears, then it goes into a white background with multiple light-purple random lines, and quits there. On the 32-bit release, the purple screen appears with no menu, with an error message.

My system has an AMD64 processor, two hard disks: one for Windows, one for Linux. I used to have Ubuntu Hardy Heron on it (not the LTS version), so I erased the drive.

MD5 sums are okay for both Ubuntu downloads.

Any ideas?

Try using the "nomodeset" parameter.

Few days ago I ran in to similar problem. I usually don't reboot my machine, only when updates requires to do so. And now I can't get past the Ubuntu logo screen with five red dots on without any change. but system is running fine I can log into if (from other machine over ssh) and access any files what ever I have shared, etc. but screen stays like that without change ... anybody knows why?
