I purchased the DC32IYE Intel NUC:
Intel Wireless Card
Windows 7 Home
The system boots normally when "Legacy boot" is selected from BIOS, even though there is no boot drive listed in BIOS.
When I select UEFI boot bios message appears "No boot drive"
I have updated all the drivers for the NUC from the Intel site - no luck.
Has anyone has this issue trying to get UEFI working
You might take a look at the earlier thread about UEFI on this forum Re: UEFI Boot
I think that you get locked into whatever the Bios EFI setting were during installation of the OS and they cannot be changed without a reinstall of the OS but there may be some other issues too discussed in the above posts.
