    Windows 10 UEFI Installation


    Hi people,
    I have some problem with installation Windows 10 UEFI on Samsung 850 EVO SSD.
    Actually I installed everything only my problem is because I could boot only if in BIOS is set option with Windows Boot Manager

    P1 Windows Boot Manager Samsung 850 EVO
    P1 Samsung 850 EVO

    Before I had Windows 7 Installed on other SSD in Legacy Mode.
    I want to install properly Windows 10 on Samsung 850 EVO without Windows Boot Manager.
    Is it that possible in UEFI Mode?
    My system is i7-5820K - Rampage V Extreme - Dominator Platinum DDR4 2666

    First of all, to install win 7 or 10 as UEFI, you must change BIOS settings. The settings below can have different names depending on your BIOS.
    Fast boot= Disabled
    Os = other or Secure boot=Disabled
    CSM=enabled
    Boot drives=UEFI

    Remove all other disks (VERY IMPORTANT) leaving on only the target disk. It will clean all disk.

    Boot with the Win (7 or 10) installation disk as UEFI (important), go to install - advanced - delete all partitions - Create new
    It will create 3 partitions (EFI 100M Fat32, MSR 120M RAW, Big NTFS). Install Win on the Big NTFS.
    If it didn't create the EFI 100M Fat32, you didn't boot installation disk as UEFI or didn't deleted all partitions
