Could you please tell me the command you are using?
I tested with ‘shutdown /r’ it works fine to me without and with Fast Boot. BIOS version
Please let me know if you have any special configuration in order to replicate it.
I am simply choosing “Restart” from the Windows 10 Shutdown menu. If FastBoot is not enabled in the In the BIOS menu, the POST process fails to complete, the system hangs for about 30 seconds and then fails to reboot with the message "BIOS has detected unsuccessful POST attempts". I can then enter "Y" and get access to the BIOS. I make NO CHANGES but use the F10 key to same my non-existent changes. NUC then boots successfully without hanging. I’ve watched the system carefully during the boot process. After a hibernation or complete shutdown the power light on the NUC turns off completely. Then the NUC will boot successfully whether FastBoot is enabled or not. If I execute the Restart command from Windows, the NUC DOES NOT completely power down. If fastboot is enabled, it boots OK because I assume the POST process is skipped when FastBoot is enabled. POST is NOT skipped if FastBoot is disabled. Then system then hangs.
This has nothing do to with Windows 10. It occurs before the OS begins to execute. Yesterday, I installed another version of Windows 10 on a second physical drive in the NUC. The second version of Windows has the same issue. The NUC hangs if a Restart command is executed and FastBoot is disabled.
I’m running the current BIOS version dated June 3, 2016. I reflashed the BIOS yesterday, but that did not fix the problem. I’ve been working with David Bennet of SimplyNUC. He suggests that I go ahead and use the BIOS recovery feature where the jumper on the motherboard has to be changed,, etc. I’m going to try that process this morning and see what happens. By the way, the NUC did not have this problem for the first couple of days after I bought it. So it’s something I did that’s caused the problem.
Thanks for responding.
PS. I went ahead and executed the BIOS recovery. That did, in fact, solve the problem. However, I discovered the instructions regarding how to execute the recovery process did not work on my NUC. If I remove the jumper, the system just cycles through the powerup process and never displays the menu. SO I put the jumper back on and followed the same instructions. This time the menu was displayed and I was able to recover the BIOS. As hoped, this solved the problem. I'm not sure how this happened. I typically avoid making changes to BIOS, since it's a good way to get into trouble. As far as I know, the only thing I changed from the defaults was to enable/disable the fastboot.
Thanks for your help.
Great to know that you could fix this problem and your Intel® NUC is working as it should.
OEFVet, did you try following these steps?
Fast Boot is a feature in BIOS that can help to reduce the time it takes to boot your computer; here you can get more information about Fast Boot:
The instructions for the BIOS recovery process look to be dated. Note there is no mention of Windows 10.
I'm also seeing some problems with USB mouse or keyboard not recognized when FastBoot is enabled in the bios and a "Restart" command is executed from Windows 10. I ran into this problem after I installed a second Windows 10 Preview version on the NUC on a different M.2 drive. I could not change the default OS after doing a restart because the keyboard and mouse were inoperative. Mouse and keyboard work fine after a cold start. All of these "Restart" issues seem to be related to the NUC not completely powering off after a Restart command.
Yet another problem that I think has been well documented. If a Logitech Unifying Receiver is installed in the USB 3.0 port next to the port that provides a charging voltage (on the front panel) and a USB thumb drive is installed in the charging port, the mouse and keyboard will behave poorly or not at all I think that's because of the 2.4 ghz noise generated by the device in the charging port.
No I have not fixed it. The recovery mode just puts me on an endless restart loop. Not a big deal; I was able to update the bios another way.
I do not run fast boot; I am curious though: Under "Fast Boot" is the yellow USB port disabled until OS loading? What about the internal USB headers? If I go with a Thunderbolt/USB-C monitor; under fast boot at what port with the TB3 port go live?
donkrell Off topic; there is a ton of noise on the front panel usb ports; USB Isolators claim to solve this problem but I am unable to locate one for USB3.0.
- Under "Fast Boot" is the yellow USB port disabled until OS loading? Yes, it would be disabled.
- What about the internal USB headers? It would be disable too.
- If I go with a Thunderbolt/USB-C monitor; under fast boot at what port with the TB3 port go live?, none of the ports would be enable.
If Fast Boot is enabled, Boot from Network, Optical, and Removable Devices are all disabled, also Video and USB devices (keyboard, mouse, drives) will not be available until after the operating system loads.
If Fast Boot is enabled, you cannot access BIOS.
