Tberdy Posted May 28, 2014 Share Posted May 28, 2014 The menu you took in photo is only the UEFI boot menu. When you install OS X, only the OS files are installed and not the bootloader, because Macs already have one build in the EFI firmware. In the case of the N56 (I own a N550JV), the UEFI BIOS is looking for a FAT32 partition (EFI Partition) with a correct bootloader (x64 "file".efi like the Windows Boot Manager). So you have to install Clover Bootloader (the only one which can boot in UEFI mode) on the EFI partition (fat32). The default install volume for CLover is your OS X partition, but this partition is in HFS+, a filesystem that is not supported by Aptio UEFI. An other solution is to disable UEFI Booting (I have an option called CSM Boot in my N550JV BIOS) to force the BIOS to load the MBR and then the PBR to finally load the the bootloader (Clover or Chameleon). I can advice you to use Clover in UEFI mode because it's a more "vanilla" solution PS : you "see" your DVD Drive because your computer detect a valid bootloader (Clover) on the DVD No detected a valid bootloader = no display on UEFI Boot Options Link to comment Share on other sites More sharing options...
tomee3057 Posted May 29, 2014 Author Share Posted May 29, 2014 When I use MBR partition, disk is on bios, This problem is only by GUID partition. thank you. Link to comment Share on other sites More sharing options...
Tberdy Posted June 13, 2014 Share Posted June 13, 2014 When you use GUID, your BIOS wants to boot in UEFI mode so it expect to find an EFI partition in FAT32 fs. If you only install OS X, the BIOS only see a HFS+ partition and it cannot boot because HFS+ fs is not supported on PC. You may format your disk in GUID, create EFI partition (fat32, 300mb), and OS X partition (HFS+). Then install CLOVER EFI (the only osx bootloader which support UEFI boot) on EFI partition. After, if clover is not automatically detected, you can add the clover boot entry in the BIOS : Add new boot entry > select HDD partition > EFI directory > CLOVER > CLOVERX64.efi Link to comment Share on other sites More sharing options...

I was reinstall mavericks and use MBR. By MBR its no problem. But thank you . Link to comment Share on other sites More sharing options...
