zavvnao Posted September 1, 2011 Share Posted September 1, 2011 I installed Lion onto my PC with GPT partitioning. Then I installed Windows 7 right afterwards. Now I can only boot into Windows 7 and not Lion is there anyway to fix this? Thank You.

Houbos Posted September 5, 2011 Share Posted September 5, 2011 Well, your boot loader has been rewritten. You'll need to reinstall it. Look for dual-boot chameleon guides in this forum. It can be tricky (setting which partition is active etc.) Boot into Lion from USB and install latest Chameleon. There's even version you can install from Windows: http://www.insanelymac.com/forum/index.php?showtopic=170079 Link to comment https://www.insanelymac.com/forum/topic/266925-dual-boot-windows-7-and-lion-question/#findComment-1744527 Share on other sites More sharing options...
The Windows Tweaker Posted September 20, 2011 Share Posted September 20, 2011 Could you tell me how you installed Windows 7 on a GUID partition table?
