[el capitan] Clover problem with booting GA-Z97X-UD5H-BK/i7-4790k after Yosemite

[tooloudtoowide]

mb: GA-Z97X-UD5H-BK with i7-4790k BIOS F8
gfx: Gigabyte R9-280X
RAM: 16GB

I have this setup on Yosemite with Clover without any problems (not to mention sound resolved by SoundBlaster on USB) for more then one year. Decided to move to El Capitan more because of updates on Final Cut Pro.

I had two SSD drives and two HDDs inside. First SSD (250GB) is for system/soft - for Yosemite it had two partition (system/temp) but during update I have decided to move back to one partition scheme for this drive.

I had created pen, all as mentioned in guide, updated BIOS to F8, then I went thru install, rebooted, finished install as in guide with Multibeast, rebooted - as seemed to be ok. I have turned off the computer, removed the pen and fire up this after a few hours.

It has previous version of Clover and not booting (prohibited sing) after a half of minute. If I put the pen - nothing changes until I will force booting from pen - then it switches to new Clover and |boot from HDD| starts system.

Clover Configurator shows EFI partitions on every HDD which is a bit scary for me as two HDD are archive drives and I have never used them to boot or make EFI partitions.

So I have a kind of crazy mess with Clover:
1. how to get rid of boot mess - I remember that I had temporary problems with booting from hard drive with Yosemite, but I have manage to resolve it. I assume that kind moving/copying/overwriting what I have on hard drive EFI will solve then problem, then question is what is best method to get free start without pen drive.
2. how to get rid of multiple EFI partitions. They exists on every physical hard drive even I have never used these drives to boot.
3. is it possible to erase whole EFI partition from boot drive and make it again with new installer? Disk utility does not see it even mounted via Clover Configurator. Mount two partitions - for pen and hard drive then erase hard drive EFI with content of pen drive EFI?

Any help and clues will be more then helpful.

ok, partly solved - I have copied EFI content from pen to hard drive EFI - not boots without any problems.

how to carefully get rid of these EFI partitions from the rest of drives?

I had a similar issue with multiple efi boot records.

It's solved for me.

It is not possible to eliminate EFI partitions if you format the drive with OS X disk utility. It will format the drive with an EFI partition by default. You can format the drive with diskpart in Windows command window and get rid of the EFI partitions or use your favorite 3rd party app to reformat your drives.
