per4itejib Posted February 10, 2016 Share Posted February 10, 2016 Hello, everybody! I've installed El Capitan on my notebook using Clover EFI method. In BIOS I have this options: UEFI Boot: Enabled SATA Mode Selection: AHCI And for all external drives (USB) I have two boot options, e.g: WD 3200BEV External1.75 UEFI: WD 3200BEV External1.75 For my internal SATA drive I have only "P0: ST9500325AS" option, so I can't boot from it to run El Capitan . If boot from installable USB, and then select proper entry in Clover - all works fine. Please, help me to figure out if I can somehow boot from my SATA drive in UEFI mode?Sorry for lame question/language. Link to comment Share on other sites More sharing options...
Hangten Posted February 10, 2016 Share Posted February 10, 2016 Use the older Disk Utility in debug mode mount EFI on your installer and then EFI in your HDD and move the EFI from the installer to your EFI on your HDD http://www.insanelymac.com/forum/files/file/480-disk-utility-patched-v2/ Make sure you copy your installer EFI and delete replacing the one in the HDD Your using Clover Im thinking....

per4itejib Posted February 10, 2016 Author Share Posted February 10, 2016 Thanks for your reply, but problem is not in EFI partition. My BIOS has UEFI options even for MBR/NTFS flash drives.I've tried even to create custom boot entry with efibootmgr, and this entry even was visible from BIOS, buy selecting it didn't do anything.

Hangten Posted February 10, 2016 Share Posted February 10, 2016 ST9500325AS so if you take that out and use an external drive cradle to USB. What happens? Link to comment Share on other sites More sharing options...
per4itejib Posted February 10, 2016 Author Share Posted February 10, 2016 I've installed El Capitan the same way on my external WD 3200BEV. It works like a charm. Link to comment Share on other sites More sharing options...
per4itejib Posted February 12, 2016 Author Share Posted February 12, 2016 Solved my problem. Added new boot option in BIOS - I have American Megatrends one - with "\EFI\CLOVER\CLOVERX64.efi" path. And now laptop boots from SATA drive in EFI mode. Link to comment Share on other sites More sharing options...
