How do I install Ubuntu on a hp pavillion 753n.
 

I create a Ubuntu boot disk 11.4 and selected Install all I got was a little white box near the bottom right of the screen. I got a new hard drive and wanted to try the linux operating system. With the boot disk the computer does boot from the cdrom drive, but I can't get it to install. After hitting forward on the screen preparing to install ubuntu the screen it says installing and gets stuck at that point. Booted from cdrom got as far as the "Who are you?"
screen then the screen went blank but I can still see hard drive activity. Is it formating the drive?

That's not much to go on. It should boot into the Live CD interface with an "Install" button on the left.

How about taking a picture of the computer with the little white box and post it as an attachment to the message (click "Go Advanced" to add an attachment)?

I think it is my cdrom drive has failed. Will replace.
