aww Posted December 17, 2014 Share Posted December 17, 2014 i would like to sign off for 3 months, but i did talk to you, so, i will try to finished, this thread with you. is this your Motherboard? ASUS P8Z77-V LK on English Manual page 3-30: BIOS setting 1 Enables both UEFI and Legacy boot. 2 Enables the Legacy boot, and disables the UEFI boot. 3 Enables the UEFI booth, and disables the Legacy boot. Asus use F8 to enter Boot, instead of F12 If you want to keep you Window7/8/8.1 in MBR (legacy mode), Set BIOS setting (1) or (2). If set to (1), you need use F8 to go to boot screen and select boot drive, every time you start your PC. (this is my setting on my UEFI PC) it means, install OS X in GUID and with CLOVER in your case, there are NO advantage of doing this. In My case, my windows 8.1 was installed in UEFI mode, 1 can start windows on less than 10 Seconds. In Your case, windows in legacy mode, may take more than 1 minute to start. if set to (2), you need to install OS X in legacy mode with CLOVER or CHAMELEON LOADER. set starting Hard drive to OS X hard drive and use loader boot option to select window drive. (if window in in MBR, you see only 1 drive, if windows was installed in GUID, you will see 2 drives, boot the system drive). if you know chameleon loader, very well start with chameleon and move to clover later. if you really want to take full advantage of UEFI and window's boot manager, set BIOS to (1) and re install Windows in UEFI mode. You can not be in (3). Reason, by definition: UEFI means secure boot ENABED, it Mean, old VIDEO card like ati 5450, nvidia 8600GTS, will not boot ( you will see blank screen) VIDEO CARD must be UEFI ready. By Definition, windows boot manager will be the primary manager, window will not allow NON-WINDOW partition to boot. (NO OS X , No CLOVER, NO LINUX) If you want other to help you, Ask your question clearly, list you hardware in details, list your boot log, I still assume, this is story II.
