Each time I boot my NUC on Windows 10, I'm offered to install a new version of the BIOS. Download works, then it asks me to reboot to install. I reboot, but the installation doesn't proceed, it goes back to Windows. I'm asked if I want to install the new version again. I tried to download and copy the .BIO file to a USB stick, but when I reboot and press F7, the USB stick is not displayed in the list (I tried to format it as FAT32 and NTFS).
