Luky Luke Posted February 22, 2010 Share Posted February 22, 2010 I have a 250 gb hdd with 2 partittions on it. One with WIN 7 and one with OSX on it. De disk is formated GUID. First i installed win7 and after that installed OSX 10.6, the problem is now that i can't boot osx without a thumbdrive with PC EFI on it. I installed PC EFI on the OSX disk but than i couldn't boot anything not Win7 or OSX. I mannaged to restore te boot record so i can boot win7 again. My question is how can i boot both of the operation systems, for example boot and get the chamelon screen where i can choose a disk to boot.

oldnapalm Posted February 22, 2010 Share Posted February 22, 2010 When you installed PC_EFI, did you install to the Snow Leopard or EFI partition? My suggestion is to install Chameleon manually and when you write boot0 to MBR use fdisk included in the binaries package ./fdisk -f boot0 -u -y /dev/rdisk0 it writes only the first 440 bytes (does not mess with Windows 7 boot).
