I've been trying to set up dual boot with Win 10 and now adding Debian Linux. I have a NUC7i7DNKE with 32 GB of RAM and a 2 TB Intel PCIE drive with 230 GB of unallocated space in hopes of putting Linux partitions in that unallocated space. I try to load a network installation image on a 64 GB flash drive, but it won't let me boot to it. Is this a Secure Boot problem in the UEFI setup? Is there any way around it? Thanks for any suggestions!
