    Cannot find "Windows Boot Manager" in UEFI BIOS


    Yesterday, after many, many problems with my computer, I finally decided to reinstall Windows 8.1 Pro onto my ASUS X200CA netbook. However, after backing up and reinstalling the OS, I found that when I tried to disable "Launch CSM" in my BIOS, all of my boot options would disappear and my laptop would continually boot into my BIOS. When I re-enabled "Launch CSM", the boot options would reappear - however, it had not included the "Option #1 - Windows Boot Manager" that I had seen in my other installation.

    Please help,
    Thank you in advance,

    If you have an OEM PC that came with Windows 8 preinstalled and if you want to install Windows 8 (core/Pro) 64-bit, you don't need to change the default UEFI firmware (BIOS) settings.

    Along with what Genet mentioned, you probably reinstalled the OS in Legacy mode, which is why you don't see the Windows Boot Manager.

    You might allow the system to boot to the drive and if it does boot, check the Disk Management windows to see if it shows an EFI System partition.
