  2. Windows 10 install fail 0x80070020 - 0x2000A ... SAFE_OS phase ... PREPARE_FIRST_BOOT operation

    Trying to install win 10 came out this error, "0x80071AA8 – 0x2000A .... prepare first boot". An expert suggested me to open BIOS for setting "UEFI BOOT" "ENABLED". Done, and all works right, no more error. My notebook: Asus X54H.
