Installing Ubuntu: "Loading Bootlogo..."
 

I made a disk as per the instructions of the Ubuntu website for 12.04 for installation on my Dell Latitutde D620 laptop and it gets stuck on the message "Loading bootlogo..." after I boot from the CD.

How do I fix this? And any other tips for installing on the D620 would be greatly appreciated.

The first thing I would do is test that CD in another computer. The odds are strongly in favor of it's being bad media. Also, in case you did not do so, test the downloaded image against the MD5 sum: https://help.ubuntu.com/community/HowToMD5SUM

Is it possible it's stuck on "Loading bootloader" as opposed to "Loading bootlogo"? That would seem more likely, as the bootloader is the first thing that loads.
