Nice job. I have an Nuc 5iMyhe running el Capitan, and best I can get going following directions in detail is a no sign at about half way on line when booting thumb drive in NUC. What am I doing wrong?

Hello - I installed El capitan to my NUC5i3MYHE a couple of years ago and it all ran fine. I decided tonight to make it dual windows boot as per the guide. I installed Windows fine, then put my USB to get back to OSX. I have followed the guide but when I eject my usb and restart the NUC says there is no bootable media and I have to reinsert the USB to get back to clover options. I have attached a screen shot of the EFI partition drive where I have renamed the file and copied in the CLOVERX64.efi file. Can anyone tell me where I'm going wrong?

No renaming of any files required.
Renaming files is really the wrong approach.

See post #2 of the Clover laptop guide for details on using efibootmgr in Linux to setup a boot entry for CLOVERX64.efi.

Thanks - I had a read. I don’t really have access to or understand linux or Ubuntu. Is there a reason why renaming the file didn’t work for me? Can I solve the problem in OSX?

You can create a USB with Ubuntu and boot directly to it, no need to install.
See ubuntu.com for details.

Note also that the correct rename procedures are in the same post #2 instructions.

Thanks for the reply - I'm quite novice at this and a little confused. I read post 2 again and have renamed the bootmgfw.efi file to bootmgfw-orig.efi as per post 2 but still get no bootable media notice on restart. I had a look on Ubuntu.com but couldn't figure out how to make USB. Also having read post 2 I'm not sure what to do even if i do manage to load Ubuntu. Is there anything else I could try in OSX? Also when booting OSX quite often I get the No entry sign and it takes a couple of attempts to boot which didn't happen before when it was only OSX. And the display is a little glitchy now too - does this mean anything? Thanks for your help - much appreciated

You should check your BIOS options.
Also, check your EFI partition for expected content (eg. copy of CLOVERX64.efi in \EFI\BOOT\BOOTX64.efi).

Once you boot Ubuntu, use the 'efibootmgr' commands as described in the guide from Terminal.

Hi Thanks again for he reply. I don't want to trouble anyone but I'm really keen to get this last little bit sorted! when you say "Also, check your EFI partition for expected content (eg. copy of CLOVERX64.efi in \EFI\BOOT\BOOTX64.efi)." does this mean I should replace the BOOTX64.efi file with the CLOVERX64.efi file, or put it next to it, or something else. I've attached a screenshot of my EFI partition - does anything look off here? Thanks again!!

Also should there be a UEFI: M.2 SATA OSX bootloader in the list in BIOS? Any idea why it's not showing if should be there?

BOOTX64.efi is likely already the same as CLOVERX64.efi, as that's what the Clover installer does.
You can see in the image that each is the same/similar size (660KB).

You need to add a UEFI boot entry for Clover (use efibootmgr in Linux), such that you can set priority to Clover instead of the Windows boot manager.
