sercio Posted July 1, 2014 Share Posted July 1, 2014 Hi guys, Ok, I'm probably missing something big time but here it goes. I'm trying to make a triple installation of Mavericks / Linux Mint / Windows 7 from a GPT disk, with UEFI. I've tried to install and boot the Mint and Win 7, they both boot fine via UEFI with the 200 mb EFI partition formatted in FAT32 I've also installed the Mavericks from a usb stick, which contains chameleon. After booting it up with chameleon, I've tried to install the clover to a USB stick with UEFI, which also boots fine. (Althought I did not settled with kexts and DSDT yet, Clover comes up just fine when booting up from usb stick.) After that, I've tried to install the clover to the hdd (fresh installation), with Clover installer, but I cannot see the UEFI option on boot selection menu during startup. Then I tried to copy the EFI folder from working USB boot up stick, but that does not work as well. Then, I've tried to install the Windows 7 again with UEFI, which boots totally fine from hdd WITH uefi. Then I tried to copy the contents of the USB to write over the EFI folder in EFI partition, still no luck. I've restored the backup of Win 7's uefi contents, then after that, tried the Clover installer over that, but all I see is the Windows 7's EFI entry on the boot menu. I'm using the last version of clover r2721 (or at least, it was the latest when I tried this.) So guys, what am I missing? Quote Link to comment Share on other sites More sharing options...
blazinsmokey Posted July 1, 2014 Share Posted July 1, 2014 I had a hard time at first too. Stil learning the ropes but I may be able to help a bit. Make sure your partition table is not a hybrid, this will give you all sorts of hell. I tried what you are doing now without linux. EFI partition -> Windows partition -> Mac Partition. My mistake out of many mistakes was installing Windows first by booting directly with my install DVD instead of booting into my Clover Mavericks USB installer. You want to boot into Clover and have Clover load your Windows install media. I would assume same with linux. What eventually worked for me was booting into my Clover Mavericks Installer first, using Mac's disk utility to setup my partitions. I wiped the whole disk then seperated into 2 partitions. The first for Mac as mac journaled and the second for Windows in msdos format. I then installed Mavericks into the first partition, it will create the EFI and recover partition itself. After rebooting back into Mav with the USB installer and installing Clover on the drive I worked on getting Mav booting without my USB. I then installed Windows by booting straight into Clover first then selecting my DVD drive to install Windows. During your Windows install when it restarts it will reboot again into clover and you must select inside clover your installing/new Windows. Good luck.

sercio Posted July 2, 2014 Author Share Posted July 2, 2014 Hey, Thanks for the hints. I have two questions about your answer: 1. How to check if I'm working on a hybrid EFI / MBR drive? 2. EFI is booting by just using the files on boot partition / EFI folder, right? If so, why it does not work when I copy the EFI folder from my bootable usb? That I could not figured out...

redneck Posted July 2, 2014 Share Posted July 2, 2014 Have you tried to use a Chameleon 2377 Yosemite on a usb drive. or install boot loader on your HD. I use this to boot all my OS, win or Mac (yose/Maverick) Quote Link to comment Share on other sites More sharing options...

I used gdisk via Mac terminal to check and repair my issue. http://www.rodsbooks.com/gdisk/ 2. Yes basically it goes bios-> EFI ->OS of your choice. I had the same issue I could boot into Mavericks with my USB without issue but without it using Clover on the boot partition it would fail. These are the only settings checked off when installing Clover to my boot partition. Install Clover in the ESP Bootloader -> Install boot0ss in MBR **here you might be where your problem could be, I forget my previous selection but this helped me as well CloverEFI -> CloverEFI 64-bits SATA Install RC scripts on target volume Install Clover Preference Pane Again I highly recommend installing Mavericks first and just get that booting on it's on with clover's efi first, that way you know it has nothing to do with your windows install rewriting or messing up anything. Then through clover boot point to your windows install and go from there. Quote Link to comment Share on other sites More sharing options...

I use this to boot all my OS, win or Mac (yose/Maverick) No, I think that come out after I tried all these. I'll give it a shot. Thanks. I tried to use MBR boot loader approach, it works OK but the problem drives me crazy. I actually had an installation with MBR scheme and chameleon bootloader, but wanted to switch to the UEFI. 1.

griftopia Posted October 8, 2017 Share Posted October 8, 2017 blazinsmokey, can you actually tell me how you used gdisk? I'm having similar issue as outlined on this post http://www.insanelymac.com/forum/topic/328177-precision-m6500-clover-usb/ Quote Link to comment Share on other sites More sharing options...
becker666 Posted September 29, 2018 Share Posted September 29, 2018 Guys the usb boots to some sort of boot manager but cannot find instructions on how to go from there or what am i missing??? Any hint Quote Link to comment Share on other sites More sharing options...
livetechsys Posted April 13, 2020 Share Posted April 13, 2020 i know its old thread...but if someone reads....check your BIOS and if it is DX58so or any X58 simple bios you should have an entry called MAC OS X thats stuck and is written in the NVRAM, there is no such way to clean it, not even reflashing BIOS, removing cell....it permanently writes it in NVRAM its an issue with clover 5070 only way to go through it is F10 manual boot.... BUT. found the soluttion...just put a drive with windows 10 and use BOOTICE x.x.3.2 version and select UEFI and remove the MAC OS X entry...and you are good to go!
