no valid boot loader target found
I have been trying to install fedora on my laptop in a dual boot, running windows 8.1, BIOS is in a legacy mode, for the past 24 - 36 hours and I don't know what to do anymore. Anaconda doesn't want to automatically partition my drive. I'm doing it manually. I get this error message "No valid boot loader target device found. See below for details. For a UEFI installation, you must include an EFI System Partition on a GPT-formatted disk, mounted at /boot/efi."

Since there seems the be another OS on that drive, you certainly should not reformat the EFI boot partition, which is used by all the OSes on that disk. Furthermore, there must be only one EFI boot partition on the disk.
Both, Fedora 23 and Windows 8.1 work in UEFI mode (non-legacy mode), why do you enable legacy mode then?
My laptop came with 32 bit windows 8.1 pre-installed, with legacy mode enabled. I have formatted the drive using windows
DiskPartand re-installed windows 8.1 x64 in UEFI mode, and my problem was solved.
