"possible" is not the right question. The issue is one of support.
7th gen (and above) processors only support Windows 10.
You may be able to hack your way through this, but there are no drivers that support Windows 7 on this device.
You will need to check the bios settings for the boot device. Look at legacy and UEFI settings, as well as boot from USB.
Again, there is no support for what you want to do.
Installation is working now(deaktivating UEFI-Installation in Bios) with that: http://www.asrock.com/microsite/Win7Install/ ASRock---Installing Windows 7 on Intel 100 / 200 / SoC and AMD AM4 series Platforms
But after the first restart after the installation-process, i get this blue-screen:
Listen closely - there is no support for what you are doing. Try the ASRock support site, for whatever good that will do. Windows 7 is not supported on your processor.
Read what is supported on your nuc: https://www.intel.com/content/www/us/en/support/articles/000005628/mini-pcs.html Supported Operating Systems for Intel® NUC Products
And, read what is not supported: https://support.microsoft.com/en-us/help/4012982/the-processor-is-not-supported-together-with-the-wi... https://support.microsoft.com/en-us/help/4012982/the-processor-is-not-supported-together-with-the-wi...
So that implemented:
"Because of how this support policy is implemented, devices that run the following Windows versions and that have a seventh generation or later generation processor may no longer be able to scan or download updates through Windows Update or Microsoft Update:
that Windows 7 can be installed??
As previously mentioned by Al Hill, this Operating System is not supported by your NUC. If you install this OS you might not find drivers compatible with your unit.
The only way to achieve the installation of the OS is using the guide https://www.intel.com/content/www/us/en/support/articles/000017241/mini-pcs.html Install Windows 7* on Computers with USB 3.0. Please bear in mind that the image needs to be created on a 3.0 Pendrive connected to a 3.0 USB port on a machine with Windows® 8.1 Pro.
thank you. Hm, it´s not the problem to create a working win7-usb-stick and starting the installation of windows7. But after first restart in the windows7-installation-process - i get the blue-screen. I think your usb-stick won´t help there? @Win81. -> creating it on win10 is possible too: "Win7-USB3.0-Creator-V3.zip - for Admin systems with Windows 8.1 or Windows 10 installed"
Another thing is that it´s not compatible ot my nuc:
This download is valid for the product(s) listed below.
Antony S. told me, that Win7 can be installed. So if i get lan-driver and Win7 to work, this should be acceptable for me. I don´t need a fully supported os. But i get a bluescreen on the win7-installtion. So i think Antony S.-method is for beeing able to START the installation-process with win7. But the NUC7i7DNHE isnd´t able to COMPLETE the installation process. Antony S. -> Do you know more?
Thank you for your reply, o0Julia0o.
The guide I shared previously is just to get the 3.0 drivers to the image. In this case, if you are getting blue screens on the installation, there might be an issue with the image you are using.
As previously mentioned, this is not supported and the results of this might vary.
I installed a pc with this boot-stick before twice and after trying on the nuc 1 time on another pc. So the image can´t be defect. Pity - i thought your method could maybe keep away the blue-screen.
