Image authorization fail. System can not boot to this (USB) device

I just bought a NUC7CJYH and installed 8GB Crucial DDR4/2400 RAM / SanDisk 500GB 3D SSD. I attached an LG ext USB 2.0 CD/DVD/BlueRay optical drive (used often with other Windows 7 / 8.1 / 10 devices so I know it works) to install Windows 7 64-bit OEM MSFT Disk. All I get on boot is: "Image authorization fail. System can not boot to this device due to security violation ...."

I read on another board that this may be due to a BIOS setting? How do I get to the BIOS if the NUC won't even boot? And if this is the case, how do I get to the BIOS and what changes do I make?

I am totally new to the Intel NUC, be gentle.

(I intend to use a Windows 10 Upgrade Disk after installing Win 7.)

Help!!

This issue is caused by the Secure Boot feature being enabled. To disable Secure Boot, you need to do the following:

  1. At BIOS POST (i.e. when the "Intel NUC" splash screen appears), rapidly press the F2 key over and over until the BIOS Setup (Visual BIOS) display appears.
  2. Click on Advanced, then Boot and then select the Secure Boot tab.
  3. Uncheck the Secure Boot option.
  4. Press F10 and then select Yes to save this change and reboot the system.

I do not believe that this will help you, however. Windows 7 is NOT supported on this NUC and may not load. Even if it does, as far as I know, Microsoft has withdrawn support for upgrading from Windows 7 to Windows 10.

May also need to choose Legacy Boot in the BIOS instead of UEFI for Windows 7.

N. Scott Person,

Thanks very much for the Bios access information and modification to disable that boot security feature.

About that Windows 7 install. Windows 7 installation IS supported on the NUC and in fact the literature with the unit lists it as well as several pages on the Intel NUC support section, such as this - https://www.intel.com/content/www/us/en/support/articles/000017241/mini-pcs.html Install Windows 7* on Intel® NUC with USB 3.0

Microsoft does sell a Windows 10 "Update" from Windows 7 and 8.1 and there is actually still little known way to get a free update from 7 or 8.1. With a little search on the Net you can find it. The Win 7 install is only a temporary situation to facilitate using the Windows 10 "Upgrade" DVD I already have.

Thanks much!

LowelH - Great point, I might have missed that to get Win 7 running until I put a Windows 10 update on it.

I also have a second smaller SSD (250GB) that I plan to install Linux Ubuntu with KODI for Home Theater applications writing and use / experimenting. I wonder if I need to enable "Legacy Boot" for Linux too? Or does Ubuntu use UEFI ??

Thanks very much!!

No, I am not incorrect. Windows 7 is NOT supported on this NUC. In fact, Windows 7 is not supported on ANY 7th gen or later NUC. If you have something that would seem to say that it is supported, then you are assuredly reading it incorrectly. For example, the article you reference, if you look at the list of NUCs that it actually applies to, is limited to 5th and 6th gen NUCs.

On Dec 31, 2017, Microsoft shut down the servers that supported upgrading from Windows 7 to Windows 10 (even for folks who actually do have a need for assistive technologies). If you are seeing any place on the net that says that you can still do this, they are saying this based upon stale information.

Still, you are welcome to try ANYTHING that you want. Just remember, it is not supported, so don't come crying here if you have problems.

No rebuttal is necessary; I am no longer monitoring this thread.

Insults are not permitted. Consider yourself warned.

Also, You have been provided with the best advice available.

Listen closely - Only Windows 10 is supported on 7th gen and later processors. And, no settings in the BIOS will help you.

So, apparently "YOUR" people in the Intel clique are allowed to be Rude, Condescending and Offensive? Is that how the Intel inter-circle is? Where is his censoring of his offensive parts of his comments?

Big difference in providing information and delivering it with an "attitude".

I spent 20 years in the USAF, 2-1/2 years in Vietnam flying, came back with pieces missing. When you have given that much you can have YOUR attitude too ...... AI

First, I am not an Intel employee.

Second, no one was rude, condescending, or offensive to you. You were merely given the straight facts. If you are offended by the answer, that is your problem.

No matter your past, you do not have any privilege to insult those trying to help you.
