Reboot off your USB key installer, interrupt the boot process and point to your freshly made Lion installation/HDD Lion partition. Once in Lion, re-install Chameleon and, if required, update to v2248 using Chameleon Wizard.

 

EDP does not install Chameleon, no, it merely updates it if you choose to do so; however, myHack should have done it but, sometimes, this fails...

Download a Chameleon installer off the web, but it looks like you've sorted that part out...

 

Try options such as PCIRoot=1 npci=0x2000/0x3000 GraphicsEnabler=No, you know, the usual stuff. Did you read the various existing posts about the Optiplex 745?

Do you mean ATI Radeon Pro X1300 (X300 is a old laptop graphics chip if I'm not mistaken)? That is unsupported in Lion and above, only in SL (I posted the way to do it). The built-in Intel GMA3000 graphics is totally unsupported under Mac OS X.
