I am trying to Install Fedora 23 on a MS Windows 10 Dual Boot Lap Top using these directions and I got all the way to "accept changes and install" when it gave me the error and said I need to add a "biosboot" to the mount point but I have no clue where to put it like before /boot or / or where? Was following this tutorial and would really like to get this up and running because I really want to finish my courses in Pentesting . I know the very basics of PC,s running windows and I have fooled around with Ubuntu and Mint but I know nothing about scripting or cmd line work. Thanks for the assistance.

You are doing a BIOS installation. That's why you need biosboot partition. You don't have to choose to mount it anywhere. Just make a partition at least the required size and choose its format to be of biosboot and it will sort it out. P.S. It is recommended to do a UEFI Installation.

And just a small hint -- you don't have to create the partitions manually just use automatic partitioning or use link "Click here to create them automatically" in custom partitioning to let Anaconda (Fedora installer) create them for you including biosboot and all other neccesary partitions/devices.

@ifohancroft: regarding your recommendation. That depends very much of your second (third...) OS! If your Windows is a BIOS type installation, don't change the settings, or you will break your installation, and vice versa in case UEFI Firmware is currently enabled.

The answer is correct. This is a UEFI computer, but somehow it's had the CSM-BIOS (UEFI compatibility support module) enabled. This is usually an option like "Legacy boot on/off" or very weirdly named "UEFI on/off". There is no practical way to support different modes for dual boot. Windows 10 invariably was installed with the CSM-BIOS disabled, so it needs to stay that way when booting Fedora. There are some systems that link CSM-BIOS/legacy boot mode when booting off optical media. How are you creating the install media? If USB stick, how was this created? It might not be UEFI boot capable if you used something like unetbootin. The best most reliable way to do this is with dd. There may be a working prerelease of Fedora Media Writer (formerly Live USB Creator) for Windows that I'd try before using any of the non-Fedora USB media creators.
