Unable to boot Live CD

[cheics]

I am unable to boot 9.10 or 10.04 Live CDs.

9.04 can boot.

When attempting to boot the LiveCD/USB (I have tried both), if I attempt the basic install/start/check CD, I get a blank screen.

If I use the option selection to set nomode(something) command (I will verify later, posting from work) with verbose and quiet disabled, I can get further, but can still not boot.

Any ideas as to how to get a boot of of the LiveCD?

Well..The first thing to do would be to check the CD and iso. If you still have the iso around, you should check and make sure the hash is the same as the one on the site.

So the hash of the ISO is the same as the one on the site

Can you please tell us what kind of graphics chipset you have?

Also, look here for some options to get the LiveCD booted:

I have an nVidia chipset (8800 GTS)

The mode I had tried earlier was "nomodeset". When running with quiet off and verbose on I did get some text (therefore some additional troubleshooting)

Again, since I'm at work I will post the error messages (likeyl within an hour or two)

Thanks for the help so far
