Having thought about this some more, it would be really strange if the inability to install Debian Stretch were a BIOS problem. I mean, why would the problem exist with Debian and not with Lubuntu (no problems installing 15.10). So it must be a Debian issue. I did report the situation to the Debian developers but never received an answer. However, if anybody has a suggestion I would be happy to hear it.
Well, I think I may have figured out the problem. I have not turned off SECURE BOOT ! Ubuntu apparently has the proper signatures to use SECURE BOOT but Debian does not. DUMB ME ! I actually knew that. So, when I get around to hooking up the NUC to my desktop monitor (can't access BIOS when hooked to the large screen), I will turn off SECURE BOOT and see if that takes care of the issue. I suspect it will. I will report back once I give that a try sometime in the next couple of days.
Well, that was not the problem. I had already turned off secure boot. However, I did see an error message when trying to run the Debian Stretch (Testing) installer. The message was "failed to add i915 component master" . If I am correct this is a graphics driver needed for the HD 6000 graphics. So, for the time being (and foreseeable future) I will have to be content with running Ubuntu on the NUC5i5RYH.
I suggest you to load defaults settings on BIOS, also make sure that you have the latest BIOS Version; after that try to install the OS again.
This is the latest BIOS Version 0355 for your Intel® NUC5i5RYH
Are you using straight connection (HDMI-HDMI)?
Do you get the same issue installing another OS?
Hellen, thanks for the reply.
Yes, I have the NUC connected to my TV directly via HDMI. And I have installed Lubuntu 15.10 with no issues.
My problem is with trying to install Debian Stretch (testing). It may be that the current release of Stretch does not have a Linux Kernel that supports the NUC5i5RYH chipset, but that seems a bit of a stretch (get it?). If I am correct, my NUC is using the 5250U CPU with HD 6000 graphics and the kernel for Stretch should be 4.2 or greater. I would think it would work as the kernel in Lubuntu 15.10 (when installed) was 4.2. . In any case, I have downloaded the latest BIOS (RY0355.BIO). Hopefully installing that will not cause problems with the current Lubuntu installation. Going to have to disconnect the NUC from my TV, and connect to my monitor, as I can't access BIOS when connected to the TV (screen resolution not recognized by the BIOS).
Hellen, I was just looking at the bios version on my NUC5i5ryh, using dmidecode -t bios, and see that it is
Version: RYBDWi35.86A.0350.2015.0812.1722 . So it is obviously a bit out of date.
My questions are these: will the iflash version run okay on Linux? I know it says it will but just trying to confirm. And will it work okay even though the BIOS doesn't like my screen resolution, or should I hook the NUC up to my monitor via VGA??
This is interesting.
1. I copied file RY0355.BIO to a clean USB memory stick.
2. Hooked up the NUC to my monitor so I could access the bios.
3. Booted the NUC and entered bios (F2) so I could check my settings.
4. Installed the USB stick to a front port (tried both front ports) of the NUC and rebooted the NUC.
5. On startup I pressed F2 so I could verify that nothing had changed.
6. Pressed F7 and the USB stick was NOT shown in the list of mounted devices.
What am I doing wrong?
Maybe it's a higher power telling me to not try fix it when it ain't broken!
Just to verify does your NUC works fine with the TV but with the monitor doesn’t, doesn’t it?
Also take a look on this steps they can help you. By the way try the USB with FAT32 format.
Hellen, thanks for the feedback. The USB is formatted as FAT32. I can access BIOS when commected to the 19" monitor but NOT when connected to the 43" TV via HDMI (screen resolution is 1280x720 and apparrently not supported by the BIOS).
However, I did find a solution to installing Debian Stretch (Testing). The problem is that the standard Debian Stretch installation does not have all of the firmware required for the NUC515RYH. So I found a non-standard Debian installer (still from Debian) that includes the required firmware. The installation took a LONG time as I was installing to another USB device over the internet, because I did not want to destroy the current Ubuntu install on the HDD, but eventually it got there.
So I now have the solution. Don't know if we can mark this as solved by ME, but please mark this as solved.
