HELP! i can't press the "install or remove windows 7 or later version" button

can someone help me? T_T
I want to install the windows 7 iso to my mac using bootcamp because i want to play games that doesn't have mac versions.
I tried virtual box, it worked but when i open my games, it's so laggy. I called my friends, my friends said bootcamp's performance is better so i tried it.

BUT when i open bootcamp it said "The startup disk cannot be partitioned or restored to a single partition."

so... i followed the guidelines on web and visited the apple support for bootcamp.

i still can't press the button.

as u can see i only have one partition

plz help me. i would be very happy if someone can help me

(ps. im a kid and i know a very little stuff about apple plz explain it to me clearly)

MY COMPUTER SYSTEM:
iMac (27-inch, Mid 2010)
Intel Core i5

16 GB RAM

iMac, OS X Yosemite (10.10.1), null

Go To Applications -> Utilities -> Terminal and start it, or you can use Launcher.

For each of the following lines, triple-click and use Command+C (Copy) the line, Paset (Command+V) into the Terminal Window and post the text output.

diskutil list

diskutil cs list

sudo gpt -vv -r show /dev/disk0

sudo fdisk /dev/disk0

For the commands that begin with "sudo", enter your password when prompted, the account you are logged in as needs to have Administrative rights to the Mac, and the password is not echoed back to you. The "sudo" commands will give you a warning. As long as you only use the commands mentioned here, you should be fine.

1. Please run Applications -> Utilities -> Disk Utility, choose "Macintosh HD" and click on Repair and test Bootcamp Assistant again.

2. Run SMC reset - Intel-based Macs: Resetting the System Management Controller (SMC) - Apple Support.

3. Repeat steps 1 and 2 again and test.

4. If these steps do not help, you need to backup OS X using Time machine - Mac Basics: Time Machine backs up your Mac - Apple Support and then OS X Yosemite: Recover your entire system and test Bootcamp Assistant again. If you are at this step, it indicates that your disk is fragmented and does not have enough contiguous disk space to allow partitioning.

From the SMC link posted previously,

Learn more

The System Management Controller (SMC) is responsible for many low-level functions on Intel-based Macs. These functions include:

Responding to presses of the power button

Responding to the display lid opening and closing on portable Macs

Battery management

Thermal management

The SMS (Sudden Motion Sensor)

Ambient light sensing

Keyboard backlighting

Status Indicator Light (SIL) management

Battery status indicator lights

Selecting an external (instead of internal) video source for some iMac displays

Note: Resetting the SMC does not reset, or otherwise change, the contents of PRAM, which is also known as NVRAM on Intel-based Macs.

this didn't help me, i still can't use bootcamp... is it because i have a 3TB Toshiba disk? and it's not a default disk? I think it's not compatible with bootcamp.. Am I right?

1. You cannot install Windows on an external disk.

2. You need to disconnect all external storage and only have Keyboard/Mouse/Display and the Windows Installer media (USB or USB/DVD) before your next attempt at Bootcamp.

On a 3TB disk, the partition for Windows must start before the 2TB boundary, which means your Windows must be larger than 1TB. Do you have a Time Machine backup of your OSX installation?
