Does Fedora installer see the free space, are you adding the partitions by hand or doing auto partition?

You are marking twice the 420GB NTFS partition. Is that coincidence or do you want to install Fedora there? Fedora installer needs free, unclaimed and unformatted disk space. So either choose the 205GB ("not allocated"), or delete the 420 GB NTFS partition (make sure you backup the data on there before) and let the Fedora installer claim that to create a Linux partition layout.

Once you get the error message, can you go to /tmp and post anaconda.log, program.log, and storage.log somewhere? That should be enough to figure out what's going on. Optionally, it might also help to make a screencast, if this is a live installer, you can use control + shift + alt + R to start and stop a screencast while you're in the installer. I think this has a 30 second limit, best to start recording once you're in custom partitioning, just before you try to create / mount point. The resulting video will be in ~/Videos.

Hi there.

Please check the following if you are planning to install, including installing Fedora alongside Windows

You are installing to a drive with unallocated space, do to try to install to an existing partition You have at least 8GiB of unallocated space You have no more than 3 partitions on your existing hard drive (if using a Master Boot Record / MBR), installing Fedora will create 2 partitions one for the install, one for swap space.

To alter your partitions you can use the DiskPart tool, or open "Computer Management" in Windows. Keep the partitions that Windows is installed to. This will be one titled "System Reserved", your C drive, and one with a size around 450MiB, or 1GiB which is a recover partition at the end of your drive. You can delete the others if you do not use them.

You can shrink your C Drive to create unallocated space. Other free tools are available on-line which can alter your partitions as-well.
