peluko Posted January 6, 2016 Share Posted January 6, 2016 Hello. I've managed to install El Capitan on my E6420 (i5-2520M, HD3000, 1600x900). For now what I've done is to follow the Clover guide on this forum (https://osxlatitude.com/index.php?/topic/8506-dell-latitude-inspiron-el-capitan-clover-guide/&do=findComment&comment=54621). I've used E6220 settings, and to support 1600x900 panel I've modified DSDT to enable DualLink, and for audio I've had to install VoodooHDA. By now it's working fine, but with a problem: I can't manage to boot Clover from the internal HDD, I have to boot from the installer USB. The installer USB is MBR formatted, and the internal HDD is GUID (it has to be GUID to install OSX). I've tried to: - Install Clover in legacy mode - Install Clover in UEFI - Create a UEFI entry in the BIOS And I can't boot. When it says 'attempted to boot UEFI volume from legacy mode' I try to boot UEFI (creating an entry in the BIOS) but then it says that can't find a boot device. And if I use F12 to select the UEFI entry, it goes black and never boots. Any hints? Thanks. Link to comment Share on other sites More sharing options...

peluko Posted January 6, 2016 Author Share Posted January 6, 2016 Hello Jake. I've done so, as this is what you say on your guide. But it can't boot, the disk is not detected as bootable. When I do this installation I get an empty EFI partition and an EFI folder on the OSX hd root. It's driving me crazy. I've been looking if BIOS has some settings that protects MBR or something so, but I don't find anything useful. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted January 6, 2016 Moderators Share Posted January 6, 2016 Copy the EFI folder from the USB to the empty EFI partition. Link to comment Share on other sites More sharing options...
peluko Posted January 6, 2016 Author Share Posted January 6, 2016 I've done that too. No luck. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted January 6, 2016 Moderators Share Posted January 6, 2016 Sent you a PM Make sure BIOS is set to Legacy and SATA Operations to AHCI, secure boot disabled. Link to comment Share on other sites More sharing options...
peluko Posted January 7, 2016 Author Share Posted January 7, 2016 Hello again Jake. BIOS is set to Legacy and AHCI (I can boot El Capitan on SSD using the install USB). I can't find anything about Secure Boot on my BIOS. More ideas? Thanks. Link to comment Share on other sites More sharing options...
peluko Posted January 7, 2016 Author Share Posted January 7, 2016 Hello again. I've found the solution. My disk was formatted using CoreStorage (it seems to be the default, for supporting FusionDrive), and it has to be disabled in order to boot in Legacy mode. The solution was to revert it: diskutil corestorage revert /dev/disk1 /dev/disk1 is a virtual disk created for corestorage, the physical disk is /dev/disk0. Thanks anyway!! Now I have to activate bluetooth, let's go! 2 Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted January 7, 2016 Moderators Share Posted January 7, 2016 Hmm, never seen this on Clover but only on Chameleon loader which I have documented on my Chameleon guide for Yosemite. Link to comment Share on other sites More sharing options...
