Raiders Posted October 12, 2011 Share Posted October 12, 2011 Hey, When I boot up into the Installer, erase the previous Snow Leopard HDD and call it 'Lion', and go to install on that HDD, I get a message: To install on this disk, open Disk Utility by choosing Utilities > Disk Utility, and repartition this disk using "GUID Partition Table." Important: you will lose all data on this disk by repartitioning it. On this HDD, I have 3 partitions. Windows 7 partition, RECOVERY partition (always been there) and the Lion partition. Windows 7 was installed first... Is there a problem, is it not possible to reboot? The USB installer obviously works fine because I booted into it, it just won't let me install onto the Lion partition because of that message. I am following the guide by MaLd0n, if that helps. Any help? Link to comment Share on other sites More sharing options...
Bobert01 Posted October 13, 2011 Share Posted October 13, 2011 so i take it that you have formatted the lion part of your drive as mac osx extended journaled also ? Link to comment Share on other sites More sharing options...
Gringo Vermelho Posted October 13, 2011 Share Posted October 13, 2011 Windows 7 was installed first... You can't install retail OS X on an MBR formatted drive without modifying something in the installer packages. Link to comment Share on other sites More sharing options...
