lolcatman Posted January 1, 2012 Share Posted January 1, 2012 Hi everyone, I got the retail Snow Leopard and I transferred it to a USB. But when I was in the installer, it said I have to have an GUID Format drive. I can't do that because I have Windows on the HDD too. All I need is someone to teach me how to edit the files on my USB to make Snow Leopard install on my system. Thanks Link to comment https://www.insanelymac.com/forum/topic/274109-retail-mbr/ Share on other sites More sharing options...
angeldust Posted January 4, 2012 Share Posted January 4, 2012 I solved same problem by converting disk to GUID (aka GPT) schema and after installing Snow Leo & updates & bootloader (from [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url]) I converted back to MBR. I have done this by tool called GPT fdisk (download / tutorial). It's a risky bussines so I recommend to backup disk before these operations. My first action was spliting the disk in Windows 7 disk management tool. Another option is to leave disk in GUID schema, but then Windows needs repair from instalation dvd-rom, and I didn’t try it. GPT fdisk is one simple executable zipped for windows and as package for osx. It should be run from external system, I guess you could add mac version to installer USB drive and then run it from installer terminal (command should look like: /gdisk /dev/disk0). I’m adding binary file extracted from osx package... gdisk-0.8.1-osx.zip Link to comment https://www.insanelymac.com/forum/topic/274109-retail-mbr/#findComment-1783421 Share on other sites More sharing options...
