I have a Clover EFI triple boot system with:

Windows 7
OS X 10.11
Ubuntu Gnome 16.04

Everything was fine until i upgraded Ubuntu to 16.04.1
After this Ubuntu would load by default.
However i am still able to access Clover by interrupting the startup process and load from EFI File.
Anybody knows how to make CLover default again?
Thanks.

Hi,

I have Windows 10 and El Capitain working under Clover (Legacy mode).
Now I want to add Ubuntu as third OS on a separate hard drive.
Can you help me to make it work under Clover without having to reinstall Windows and OS X?
If I connect a drive with preinstalled Ubuntu, will Clover "see" it? Or there is another way to make it work?

Thank you.

I have never tried this with Clover. With Chimera you needed to make sure Grub was installed to root, but I am not sure if Clover would require it.
Since you are using a separate drive, try disconnecting the Win10/El Cap drive and installing Ubuntu as you normally would.
Then reconnect the OS X drive and make it first in BBS boot order. Does the penguin icon for Ubuntu show up in the Clover screen as a bootable icon?

Now, to make everything work right, shutdown Ubuntu, insert the OS X USB installer again and boot to OS X desktop. Mount the EFI partition and rename the Windows boot manager file:

Run MultiBeast to install Clover, networking and audio and reboot to UEFI and set the OS X partition as first in boot order:

Save&Exit and continue boot to Clover - select an OS to boot:

And that, my children is just how simple it is.

Any hopes to see a Legacy version soon?

A legacy version is much trickier as it requires building a hybrid MBR to install Windows. It can be done using terminal and using gdisk. I used to run OS X and Windows 7/8/10 off of a single 1TB SSHD in a MacPro1,1 and set it up that way. Works the same when using Clover. If you want to read up on building the hybrid MBR see this article: http://www.rodsbooks.com/gdisk/hybrid.html

When you are renaming the bootmgfw.efi are you doing that in the Clover install or is that from the Windows install somewhere? On my multi-drive dual boot, converted from a single SSHD, I copy the CLOVERX64.efi file to the EFI/EFI/Microsoft/Boot (I think that is the path, don't have it in front of me) folder and rename it to bootmgfw.efi, I also have the bootmgfw-orig.efi file there.

On same drive installation rename the Win10 boot file is all that is needed - the Windows folder with the boot folder is in the same EFI folder on the EFI partition as the Clover folder.

What is the first boot drive in the UEFI BIOS order?

You will probably need to start the Clover UEFI Shell and, using the bcfg boot mv #x #y command, move the boot order around. #x is the device you want to move, #y is where you want to move it to, probably 0, the first boot device. You would bcfg boot dump, maybe, bcfg boot dump -v, look at the order than move the boot order around. Say OSX is on third in the order, Linux is first in the order and Windows is second in the order. You would then bcfg boot mv 3 0, then do another bcfg boot dump to verify the new boot order.

My system is a dual boot with 10.11.6 and W10 on separated drives. Was not possible to boot W10 by clover, only directly from uefi startup. But now, simply renaming the Windows boot manager, solve the problem. Have tried a lot of things for month of sundays. Thanks a lot, you are great.
