I did install Fedora 18 on a machine using Windows XP.
To do so I first modified the original only partition used totally by Windows and created partitions for Fedora 18 using GParted ( http://gparted.sourceforge.net/download.php )
From almost 100 GB I left only 32 for Windows (/dev/sda1, ntfs) and made a separate 4 GB patrition for My Documents (/dev/sda2, ntfs). The rest for Fedora this way
/dev/sda3 ext4 /boot 256 MB
/dev/sda4 extended
/dev/sda5 swap swap 2 GB
/dev/sda6 ext4 / 4 GB
/dev/sda7 ext4 /usr 16 GB
/dev/sda8 ext4 /usr/local 4 GB
/dev/sda9 ext4 /var 3 GB
/dev/sda10 ext4 /tmp 1 GB
/dev/sda11 ext4 /home 40 GB
After that I started Fedora 18 installation from a DVD.
Within Anaconda
* In the main menu I selected Keyboard layout, software to be included -all other options were selected by default
Then, in the partition area
+ selected the disk
+ selected the type of partition to standard
+ told Anaconda I wanted no help in doing the partition
+ then clicked on Claim free space button
+
Anaconda did recognize partition and showed this partition as Unknown, the ntfs included.
It recognized the labels as I had defined them in GParted.
Then it was only matter of setting mount points with the exact names as the labels.
And check in Reformat box.
I didn't cypher data so not to mess around.
As I clicked on Apply changes button, the partition was moved in the left box to the New Fedora Installation area at the top.
It automatically separated data partitions (/usr/local and /home) from system partitions.
Checking the Finish partitioning button brought me back to main menu and Fedora 18 installation run seamlessly.
When doing a fresh install of Windows 10 I have always had to disconnect every single other efi bootable drive. If I don’t I’m stuck in an endless loop of the same error getting. What the others have told you is correct. As long as that Linux partition is visible from the installer you’re going to continue receiving that error.
If you don’t want to back up your Linux partition so you can wipe the drive and reinstall later, you’re going to need a second drive so you can at least disconnect the Linux drive.

I had the same problem. Opening terminal and running the command
indicated that I have both MBR and GPT tables present. This happened because I had originally Windows 8 pre-installed on my computer. Windows 8 uses GPT scheme. I installed windows 7 over it. Windows 7 is using MBR and finally my disk end up being MBR with some stray GPT data on it.
This is a known problem and can be fixed using FixParts
