I've had my DN2820FYKH for a couple of weeks and I have yet to get Win7 installed fully.
Everything seems OK at 1st - the PC boots from the USB flash drive with the W7 Iso on it (created from a genuine Win7 DVD) detects the hard drive and formats it/creates partitions then the install proceeds as expected. PC reboots at the end of the Win7 install. Upon restarting, Win7 says "No boot device found". Tried reinstalling Win7 and now setup states that it can't install the OS on the HD that it installed Win7 on just 5 mins ago! After rebooting and doing the F9/change all bios settings to the recommended values (something I made sure to do before even booting off the flash drive) the Win install gives me the "A required CD/DVD device driver is missing" error message. After that it just won't let me procede further.
I tried doing a repair from the Win options and it tells me it can't repair the problem and I should enable my boot device in the bios or update my bios. I've been on ver. 0025 since day 1.
At this point I'm thinking the hd(s) I've been trying aren't compatible in some way. So I purchase a Western Digital drive that is on the NUC2820FYKH compatibility list. I also purchased an Adata flash drive from the same list.
Everything (again) seems to be proceeding normally with the install until the reboot after Win7 is done. Then the DN2820 says "No boot device found". So even with a new drive from compatibility list, the PC still won't boot into Windows.
I even went as as to format/partition/set partition as active the HD via a DOS prompt before the Win7 install and I still get the same result.
I have tried booting from both Fat32 & NTFS formatted flash drives as well as a USB DVD drive with the genuine Win7 SP1 DVD - all with the same result.
All he's I've tried show up in the bios and I changed the boot order after Win7 install so that the hd's boot 1st.
All have been tested in other systems and appear to be working normally.
Any/all ideas or suggestions would be VERY much appreciated.
