Initial install of Windows 10 home on a NUC8i7BEH. Windows never launches Missing winload.efi.


The bios memory and two SSD 500GB hard drives, one M.2 and one SATA, are all recognized by the bios. I have a MS Windows usb installer from MS.


The first time I attempted to install windows it took a little time for the OS to copy. Now it speeds through like it's already loaded. Each time I get the select 64 or 32 screen. I select 64.


Then I get a message that the winload.efi file is missing or corrupt. Telling me to reinstall from a source installer.


What am I missing?

Get a USB stick that is at least 8gb. Go to another PC (not a mac or linux machine) and format the usb stick as FAT32.


Then, go here and use the Microsoft tool to make the install media on the USB stick.


Then, make sure the nuc is in UEFI mode. Then, boot the stick using F10.


Select custom install, and delete all partitions on the drive you intend to use as the boot drive. Continue with the installation.

Follow Al's advice; the image that MS puts on the flash sticks is just awful.

I'll add some more detailed instructions to Al's advice how to install Windows 10 after you have the installation media created with Microsoft Media Creation Tool:

  1. Your bios should be set to default settings. Enter bios (press F2 during boot) and then press F9 (Y) to set defaults and F10 (Y) to save settings and exit.
  2. With the installation media inserted into slot, power ON your NUC and press F10 to get Boot Menu.
  3. In this menu, choose UEFI option of you Installation media.
  4. Follow this tutorial to continue with installation
  5. In para. 7 you may enter Product Key from the Microsoft Distribution you bought.
  6. Skip on para. 12 and continue in para. 13. Important, do not format drive where you want to install Windows, rather delete all existing partitions from this drive, till you see one unallocated space.
  7. Press Next and continue with the installation.
