Upgrading Windows version

Hi.

I upgraded my NUC D54250WYK from Windows 7 to Windows 10 and since then, i have some problems from time to time when i reboot. Sometimes, the signal on my tv is loss when i boot the nuc and i have to boot it again several times until i have a message saying someting about post launch and i have the option either to go in the bios or continue booting. If i continue booting, sometimes i can boot Windows, sometime it doesn't work. I tried to update the bios to see if i can correct the situation without any luck.

 

  • I tried to update the bios with the online option on the interface in the bios, but i get an error message about Intel cannot find my product ID
  • Tried to update the bios with an external USB drive but then, the screen loss the signal source. I waited a good 30 min before restarting the nuc and still on the same version for the bios.
  • Tried to upgrade the bios with DOS. I can see the version and as soon as its start, again, the signal source on my screen is gone and after a good 30 min. Still nothing. The same version on my bios is here.

 

Can anyone help me?

 

I'm trying to upgrade to the version WY0054

Was your Windows 7 Legacy or UEFI boot?

  1. Update Bios, using Bios Recovery from the Power Button Menu:
  2. Prepare USB stick fully formatted to FAT32 (disable quick format option during format). Format your USB on Windows machine (rather than Linux or MAC). Save the Bios file WY0054.bio (https://downloadcenter.intel.com/download/29075/BIOS-Update-WYLPT10H-86A-?product=76977) on this stick and insert it into rear USB slot.
  3. Press Power Button for about 3 seconds. Count 1001, 1002, 1003,1004. Release the Power Button. NUC should reboot into Power Button Menu. You should release the Power Button before 4-sec shut down override .
  4. Press F4 and the recovery shall start (it can take up to 30 seconds for messages to appear on the screen).
  5. When the recovery finishes, press on Power Button and hold it, until NUC switches OFF. Pull out the power cord. Remove the USB stick.
  6. Replace the power cord and press Power Button to switch the computer to ON.
  7. Enter Bios setting by pressing F2 during boot process.
  8. Press F9(followed by "Y"), to set Bios to default settings. Press F10 (followed by "Y"), to save the settings and exit to O.S. Let the NUC fully reboot.
  9. Your system drive should have GPT type partition (rather than MBR).

I agree with Leon and Al; the problem stems from the original installation of Windows 7 in Legacy mode and its continued operation in this mode as you transitioned to Windows 10. I have WY NUCs that I updated to Windows 10 via scratch install and others that I did via the upgrade process. None display any issues with boothing. I believe that the difference is that I originally installed Windows 7 in UEFI mode, including use of GPT partitioning. I realize that it will be a lot of work reinstalling from scratch, but ultimately necessary. Remember that, when Installing Windows 10, delete *all* partitions from the boot drive to ensure that a GPT partition table will be created.

  1. If your Windows is installed in legacy mode (i.e. your drive has MBR partition instead of GPT), you may convert it to GPT without need for system reinstalling and without loosing data.
  2. First, update your bios and set it to default setting as described in my previous post.
  3. Next check your partition type https://www.top-password.com/blog/tag/how-to-check-gpt-or-mbr-windows-10/
  4. Backup your drive and convert partition from MBR to GPT, without loosing data. Use Microsoft mbr2gpt utility https://www.windowscentral.com/how-convert-mbr-disk-gpt-move-bios-uefi-windows-10

Hello everyone!

Sorry for the wait.

I converted the MBR partition to GPT and the BIOS to UEFI without any luck :( The same message appear on boot. And i must reboot between 5-8 times to make it to the login screen.

I think the best solution will be to reinstall the OS from scratch.

You should be able to update Bios, using the recovery method I've described in my post above before reinstall OS. The Bios can be restored without OS installed and it is even advised to have bios updated before installing the OS.
