12.04 has been out for a few days now, I had some free time this morning to install it, and 6 hours later I'm ready to pull my hair out. I downloaded the x64 .ISO, burned it to a CD and tried to run the disc. It shows the purple screen for a few seconds, then a blinking prompt up in the left corner. I can hear the CD being read for about 5 minutes, then it goes quiet. I let it sit for a while but nothing happened. I tried running the .ISO through VirtualBox, and it worked perfectly fine, so I know the .ISO is fine. I'm positive the disc was burned correctly, and I tried booting from USB which was a disaster, but more details on that in a later post. Sorry if this is a vague post, but I'd really appreciate any help you can give me. Thanks!
