whats ur hardware config? mobo, graphic card, etc?

try this when booting from your usb drive:

interrupt chameleon by pressing any key when it shows up. then type the following:

"GraphicsEnabler=No" without the quotes

then select ur pendrive by using the left/right arrows and hit enter...

see if you can boot into the installer with just basic graphics support...

if the above is successful, that means chameleons auto graphics card detection didnt work for your card... and u would have to update the boot plist file with an EFI string for ur graphics card or use an injector to get full graphics...

if the above didnt help, could we have a look at the messages that get displayed when it boots? u will have to take a photo of it and post here...

good luck!!!
