NUC8i7HVK not booting usb stick

I have NUC8i7HVK system with 32GB RAM, (2 modules of 16), NVMe WD Black 1TB SSD.
When creating a bootable catalina os stick (AData 32GB) it’s not booting from it, while the same stick boots fine on HP laptop..
I’ve tried to make a bootable stick with the same drive of Aeomi Backup, Acronis, non of them boots no matter what.
Disabled secure boot. BIOS fw is 0067.

One thing weired is that if the PC is off completely, I press the power button and keep it pressed the PC turns on then shuts off and turn on again but with yellow light that never goes away..

Any suggestions?

So first of all, by default, if this Catalina flash drive is not capable of booting in UEFI mode (i.e. only supports the Legacy Boot capability), then it isn't going to be bootable on these NUCs. Support for Legacy Boot is in the process of being EOLed (it is simply not secure). In this case, the resolution is to (a) enable Legacy Boot (not the recommended solution, obviously) or (b) build a Catalina flash drive image that supports UEFI Boot. If you think this situation is in error, well then, you need to talk to Apple regarding why Catalina won't boot on non-Apple hardware.

The yellow light comes on to indicate that the unit is attempting to bring up the Power Button Menu subsystem (which can take some time). If you then continue to hold the power button down for a full 4 seconds, the chipset will automatically withdraw power. This automatic power withdraw is a feature of the Intel chipsets that has existed for a great many years. Once the LED turns yellow, you should let go of the power button.

This installation is part of OpenCore.. which means it’s UeFI compatible.. it boots perfectly in HP system..
also, the option of disable UEFI is grayed out so I cant uncheck it.. nor booting any installation of something..

You usually don't need to disable UEFI Boot, but (a) you might need to enable Legacy Boot and (b) remember that UEFI-bootable devices always have priority over Legacy-bootable devices.

With the flash drive plugged in, power on and use F2 to enter BIOS Setup. Browse to the Boot scene. On the main page, there are windows  that show, on left, what logical devices (partitions, etc.) are considered UEFI bootable and, on right, what logical devices are considered Legacy Bootable. What is it showing there?

Other thing to try is powering on and then using the F10 key to open the boot menu. From there, you should be able to manually select the USB Flash drive for booting.

There is no option like Legacy boot devices.. the right side is empty.
More I can tell that the same usb stick is showing macOs installer and it is loading OpenCore when plugged into my HP laptop with secure boot disabled and legacy boot enabled/disabled..

on my other NUC I can see it..

Hello @nirh216

Thank you for posting on the Intel® communities.

We are checking this thread and we would like to mention that for the Intel® NUC Kit NUC8i7HVK, only Windows* 10 and Windows* Server 2016 are officially supported as you can confirm in the following links:

Running macOS* operating systems on computer hardware not authorized for that purpose by Apple* (also known as "Hackintosh") is not supported and this may require changing different settings on the BIOS; however, what settings to change is something that can vary from one deployment to another. Intel® Customer Support does not provide assistance for this combination (Intel® NUC + Apple* OS); however, perhaps other community members can help you out.

If you would like to verify if the hardware is working fine, you may try using one of the officially supported operating systems; however, for further assistance with this configuration, we recommend reviewing this further with Apple* Support and/or Apple* forums.

Having said that, we will proceed to close this inquiry now from our end. We will leave the thread open in case other community members want to participate.

If you need any additional information, please submit a new question as this thread will no longer be monitored.

Best regards,

Andrew G.
