NUC7I5BNH does not boot after crash

[Yaco]

Hey everyone,

after a Windows 10 crash, my NUC7I5BNH does not boot from the installed M.2 SSD drive anymore. I never had any problems before.

The drive is still recognized by the bios but by neither a Windows nor an Ubuntu boot stick. I updated my bios to BNKBL357.86A.0076.2019.0219.1646 and tried all the tricks I can find on this website but none worked.

Can anyone help me with this problem?

Thank you in advance!

Hi @Yaco​ ,

1. The NUC is not booting following Bios update? Or, it was not booting before bios update?
2. Please enter bios and press F9(Y), to set bios to default settings and then F10(Y) to save those settings and exit.
3. With Windows 10 USB inserted, press F10 after power ON. NUC should enter Boot Menu. Choose UEFI line of USB stick in order to boot into Recovery Environment.

Hi Leon,

thanks a lot for your quick answer and your help!

1. The NUC wasn't booting before and after the bios update.
2. Done
3. This helps, if I boot my NUC this way both the Windows stick and the Ubuntu stick recognize the SSD! Unfortunately none of the windows repair options work. I guess I'll just copy my file using ubuntu and reformat the drive...

Hi Yaco,

Try to repair the boot sector using the following procedure. I'm assuming that your O.S. is Windows 10.

1.   Boot from your Windows 10 installation USB.

2.   Select your language preferences and click/tap on Next.

3.   Click/tap on Repair your computer at the bottom.

4.   Click/tap on Troubleshoot.

5.   Click/tap on Advanced options.

6.   Click on Command Prompt

7.   In the Command Prompt write the following command:

Hit enter after each command: 

BOOTREC /FIXMBR

BOOTREC /FIXBOOT 

BOOTREC /RebuildBcd

 Exit from Command Prompt, shut down your NUC and try to power it ON again.

Hi Yaco,

If restoring the boot will not fix the boot problem, still you may try another possibility.

1. Repeat paragraphs 1 through 5 from my previous post.
2. Click on System Restore
3. A Windows with previously stored restore points should open.
4. Choose the restore point and start the system restore to the saved configuration.
5. If the restore ends successfully, you will have bootable system.

Thank you so much for your advice!

Unfortunately I get in I/O device error using those commands in the command prompt. The last command tells me that there are 0 Windows versions.

I assume this means that there is either an error on the SSD or something on the mainboard is broken. What do you recommend to find out?

Best,

Yaco

Hi Yaco,

1. Enter Bios setup Advanced > Boot > Secure Boot and verify that Secure Boot is disabled. If Secure Boot is enabled, disable it and try again to fix boot from Command Prompt as detailed in my post above.
2. If the attempt to fix boot will be unsuccessful again and since you wrote me that your SSD is recognised while booting from USB, I suggest that first you should copy and protect your personal files to an external media.
3. Next, using Windows installation USB, boot into Advanced Startup (see my post above).
4. Try to Refresh Windows. See Option One in this tutorial https://www.tenforums.com/tutorials/4090-refresh-windows-10-a.html

Hey Leon and David,

In the end I was able to boot using an Ubuntu boot stick. I found out that the SSD was corrupt using Ubuntu to check it. But fortunately i was able to save all my data, even though some of it was corrupt as well.

Thanks a lot for all your help! This community is incredibly friendly and helpful!

Best,
