Hello again
About to completely give up. Went literally by the numbers from the first post and now does not boot at all:
Formatted USB (16GB) stick
Used the terminal code to install the media
Installed Clover v3320 and selected exactly the same settings as shown: UEFI Booting only, Install Clover in ESP, Drivers - only selected OSxAptioFixDrv-64, RC Scripts
Copied over the 2015 11 01 New config.plist folder to the Clover folder on the EFI partitoin of the USB
BIOS - all reset to defaults, Enabled both UEFI and Legacy Boot, Disabled VT-d in security, Changed Video Memory to 128, Boot USB first.
Started the NUC and selected the OS drive from Clover (the only one that was there), ran in verbose mode and this is the result. Got a new screen, that then rebooted after a few seconds, and then just kept going around in a loop? Sorry about the image, had very little time to try and catch it.
Just about give up
