How ro erase Linux of the embedded storage on a DE3815TYKHE

[Ernesto1]

I believe Linux is installed on the 4GB embedded storage of the DE3815TYKHE and we need to know how to erase it. At boot up, we cannot even access the BIOS by hitting F2. This option does not work.

I have Windows 10 loaded on a USB and have plugged it in to the NUC and it reads it and boots in to it, I figured I can erase the partition when I try installing the OS but the embedded 4GB storage is not visible.

Any help would be greatly appreciated. Thank you.

1. Please check if the BIOS Security Jumper is not installed in "Lockdown" position between pins 2-3 instead "Normal" position between pins 1-2. See page 56-57 in the Technical Product Specification.

2. Try to boot into Power Button Menu. With NUC OFF, press and hold 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. In the Power Button Menu you will have different options. See page 70 in the TPS. In order to boot into Power Button Menu the BIOS jumper should be installed in "Normal" position.

3. Try to remove the Linux entry booting from Windows USB into Command Prompt, using bcdedit utility: Remove old EFI entries from Boot Menu

Hi Leon,

Thank you for providing this information. I checked the jumper settings and yes they are in the correct position. I was able to update the BIOS to the latest version by using the BIOS security jumper option. I removed the jumper and put the BIOS file on a USB and that worked but we still cannot access the BIOS.

The F2, F7 or F10 keys do not work. We even booted into Power Button Menu option and the F keys do not work/respond when being pressed. Only the ESC button works.

After updating to the latest BIOS, the system no longer boots in to Linux but we have not erased the embedded storage, where we believe Linux is running off but we cannot access the BIOS settings.

This is really strange.

Hi Ernesto,

Try to boot into Configuration Menu: power ON the NUC with the BIOS Security Jumper removed (without any USB stick inserted into USB port). In this menu, try to click on F2 to enter BIOS. if you see F3 option displayed in this menu, click on F3 first in order to disable Fast Boot.

BTW, in BIOS, there is no possibility to erase the EFI entries. You may do this in Windows as explained in video clip, linked in my post above.
