It would help if you showed us a screen capture.
Most likely, you are accidentally applying a preset to the DNG or RAW photo, causing this to happen. Are the sliders set at zero for the Basic panel (except for Temp and Tint)? Is there only one item under History, that says Import?
I strongly recommend you fix the problem instead of using the very limited and antiquated Process Version 2003.
If you are getting "embedded" as your only profile choice, that would indicate that you are not working on a raw image. You might be using DNG files, but if they were created from TIF files you won't get the different choices. The different profiles will only work on raw images. Perhaps you should consider adjusting the color saturation levels on one of your "normal" photos, and make any other adjustments that you want to have as part of your default settings. Then save new default settings for your camera. I find that I have to do that myself.
So you're using "convert to DNG" in the import panel? That should work fine and should get you a choice of camera profiles. If it doesn't something is seriously awry. I would first import just the plain raw files and not convert to dng to check whether this is the issue or whether your Lightroom installation is messed up. What Lightroom version is this? Make sure to actually check in Lightroom Help->System info.
You should not have to revert to the ancient 2003 process by the way and just selecting the profile should give you good results already. If it doesn't I would also check your screen calibration and redo that as this can also be caused by a bad monitor profile.
