D830 dual boot issue

I successfully installed my D830 (nvidia 135M) with this process:

 


  1.  
  2. Started with this site: http://www.osxlatitude.com/edp/pre-installation/
     
  3. Create boot USB pen:
    Followed Pre Installation steps, downloaded and executed MyHack (http://myhack.sojugarden.com/guide/) to create USB pen, but use the D630 (with nvidia) bootpack rather than the D830 (doesn't work), as advised here:
    https://osxlatitude.com/index.php?/topic/419-the-d830-osx86-sl-experiance/
     
  4. Boot Dell with USB pen, follow instructions from Installation:
    http://www.osxlatitude.com/edp/installation/
     
  5. Remove USB pen and reboot. Follow post-installation instructions but choose D830 as model for "Predefined Kexts". http://www.osxlatitude.com/edp/post-installation/
     

Everything including graphics, sounds, wireless, Ethernet, battery is working perfectly.

 

I then installed Windows 7 with the instructions found at http://www.osxlatitude.com/dual-boot-osx-windows-made-easy/ . Again everything went fine, laptop boots fine into Windows 7.

 

When I boot the laptop I get Chameleon loading, I hit enter to get the boot menu and I have two choices: OSX and Windows 7. While Windows 7 boots normally, OSX doesn't. The boot starts and a lot of kexts are loaded (so the right partition is found) but suddently I get a black screen and the computer reboots to Bios. Since this is very quick I can't even notice where the boot fails. Also, if I boot from my USB pen and pick OSX menu option then the computer boots the OSX partition without problem!

 

Any idea what this problem might be? Thank you.

Once you boot your HDD OS X partition via USB key, just re-run EDP and re-install Chameleon (menu 3: installer). That will take care of things. Alternatively, check in /Download folder, you'll probably find a copy of Chameleon package there. Double click on it to re-install.

I re-installed Chameleon from EDP as advised by Hervé, but that didn't fix it.

 

It made me remember however that after installing Windows there was an update of the EDP application available and I did it prior to re-installing Chameleon. So perhaps the problem comes from this new EDP or the version of Chameleon that it installs?

 

Can I revert to a previous version of EDP? Where could I get it from?

 

Also, I have a Super-Duper complete backup of my system prior the dual boot (and EDP update), do you think restoring it could fix my problem? Or is Chameleon installed into a special partition not taken in backup?

 

Thanks for the help.

Try and reboot in your OS X partition via your USB install pen. If that succeeds, check your boot plist in /Extra and give us the list of checked/selected parameters. I think it needs npci=0x2000 for ML (well, the D630 nVidia does, to boot ML).

Merci Hervé. I decided to reinstall completely from the USB pen. It is not that long and with the wonderful "Migration Assistant" app from Apple I have been able to restore all my customizations, apps and data from the backup I had. Everything work great now including dual boot since the Windows partition hasn't been touched by the reinstall.
