lovelyzoo Posted January 28, 2012 Share Posted January 28, 2012 I'm trying to create a triple boot system. Thus far I've successfully installed Lion using Uni/[url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url], followed by Win7 on the MBR and then installing ubuntu 10.4 and then upgrading it to 11.4. At present grub2 can now boot and ubuntu and, having fixed up the hybrid MBR using gdisk, Win7. However, booting OSX fails almost instantly and then reboots. I've tried modifying grub.cfg as outlined here: https://help.ubuntu....ing#Loading_OSX but this just results in the error message 'Invalid signature'. I can boot OSX from the USB thumb drive and re-ran [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] to try and reinstall Chimera. However, this changed nothing, I still see the GRUB2 menu. Can anyone suggest how I might either: (i) Uninstall grub, making way for a Chimera install. (ii) Boot OSX from grub as I originally attempted to. I've also been discussing this on tonymacx86, see here: http://www.tonymacx8...p?f=169&t=47480 Any help much appreciated.
