I'm trying to install Windows 10 on a NUC, actually two of them. I'm attempting to install Windows from a USB stick that has the Windows 10 ISO installed. This USB setup works fine on a Dell computer.
The issue is as follows:
1. It is impossible to boot to a USB stick unless all other bootable devices are disabled or missing. The instructions say press F10 to go to the boot menu, which it does. However selecting the USB stick just makes the screen blink and then do nothing. Unless all the other boot devices are missing or disabled the NUC refuses to boot to a USB device.
So for example just say the only UEFI boot devices are the USB stick and the built in EFI shell, there are no Legacy boot devices available either. The NUC will not boot to the USB stick. You can put the USB stick up the top of the boot order. You can select the USB device to boot first. The NUC will always boot to the EFI shell and will refuse to boot to the USB stick, until the EFI shell is removed as a boot option. Then it will happily boot to the USB stick.
2. This may be a related issue. When the USB stick is the only boot option Windows 10 will not install on the drive in the NUC. Windows will come back with the following message after formatting the 120GB drive:
"Windows cannot be installed to this disk. The computer's hardware may not support booting to this disk. Ensure that the disk's controller is enabled in the computer's BIOS menu."
The hard drive, an Intel SSDSCKJW (120 GB-6.0 GB/s) is spotted in the BIOS as a SATA device. However its not spotted on this NUC as a boot device.
The situation with this drive it did have Windows on it but I blew it away. I was able to do this by booting to the Windows 10 USB stick and then formatting the drive in Windows. I could boot to the USB stick by disabling UEFI boot so the USB stick was the only boot option. After this the drive does not appear in the UEFI boot option. I have another NUC of the same type which still has Windows on it and Windows Boot Manager and the drive itself appear in the UEFI boot options.
On this second NUC I basically have the same problem but have not wiped Windows.
I've updated the BIOS to the latest version on the first NUC. I've spent hours trying to work this out. Can anyone explain why problem 1 happens & how to fix it? I just wish the NUC BIOS was basically more like Dell BIOS in that if you tell the BIOS to boot from a certain device, it will boot from that device or fail because it can't.
Regards and thanks in advance.
