I've found myself, something went wrong during the installation of Chameleon. I installed it again and now I can boot from the hdd. Thanks for the help

Thanks, I tried this guide before using myHack but It didn't boot, so I tried with myHack. I'm a bit further yet, I started again to install with MBR patch, but this time, I made a myHack drive without the patch and I applied the patch from this source: http://www.insanelymac.com/forum/files/file/145-mavericks-mbr-patch/ The install went fine on a MBR disk with a Mac OS Extended (journaled) partition, but after the install, the PC don't boot to the HDD. If I boot to the USB Drive and then select to boot on HDD hd(1,1), the gray screen with Apple Logo is comming but it stay like that. If I add -x -v to the boot options, it works So now, how can I make it to boot on the hdd without booting on myHack stick first ?

Yes I did format my HDD as Mac OS X Entended journaled. But I'm still not sure if the Optiplex 760 can boot to a GPT style disk or if I need a MBR style disk.

I tried to remake a myHack USB Drive without the MBR Patch and with this one the install go to the select destination drive menu. So the "The OS X installation couldn't be completed" error come only with MBR Patch. Should the Optiplex 760 boot to a GPT disk ? I also try to update my BIOS, now it's version A16, but still no boot on the SATA Drive if the partition is GPT.

SATA is on AHCI. When I made the myHack USB Drive, I didn't put the MBR Patch and when I use the DiskUtility to create my MAC OS Extended Partition, it create a GUID Partition Table. I think the Optiplex 760 can't boot on GPT so I try to recreate the MyHack USB Drive and select Yes to Patch for MBR. I reuse the DiskUtility to create a MBR with a single MAC OS Extended Partiton. But this time, just after selecting the language, I have the following error: "The OS X installation couldn't be completed" The only difference is this MBR Patch I think. Do I absolutely need this patch to install on a Dell Optiplex 760 ?

Hi, I've a Dell Optiplex 760 and try to install Mavericks with myHack. I made the USB Stick with myHack and also copied the Extra files uploaded by MacsRTheBomb in this topic: https://osxlatitude.com/index.php?/topic/1687-optiplex-760/&do=findComment&comment=12858 The install went fine, I located my ExtraOpti760 Folder when asked to Supply my Own Extra and I replyed Yes everytime to remove problematic extensions. When the install was finished (I suppose), the PC restarted (without asking, is it normal?) but stay on: Initializing Intel® Boot Agent GE v1.3.52.1 PXE 2.1 Build 089 (WfM 2.0) It doesn't boot on the HDD. Even if I press F12 for the Boot Options and then Select SATA0, nothing happen. What should I try ? My system: Dell Optiplex 760 Core 2 Duo E7500 @ 2.93GHz 4x1GB DDR2 No Additional Card, using onboard Video Controller BIOS Version: A13
