You haven't used isset() in your if condition so you are getting the below error

Notice: Undefined index: remember in F:\Xampp\htdocs\projeto\admin\index.php on line 35

if isset() is used you won't get any error message even if the variable is not defined

for more about isset() please refer http://in1.php.net/isset

Change your if condition from

if($_GET['remember'])

To

if( isset($_GET['remember']) )

Changed Code :

<body>
    <div id="login">
        <img src="images/login-logo.png"/>
        <div style="display:none">
            <span class="ms ok">Login sucess!</span>
            <span class="ms no">Error</span>
            <span class="ms al">Alert</span>
            <span class="ms in">Information</span>
        </div>
    <?php
    if($_GET['remember'])
    {
    ?>
    <form name="login" action="" method="post">
        <label>
            <span>Email:</span>
            <input type="text" class="radius" name="email" />
        </label>
        <label>
            <span>Senha:</span>
            <input type="password" class="radius" name="email" />
        </label>
        <input type="submit" value="Login" name="sendLogin" class="btn" />
        <div class="remember">
            <input type="checkbox" name="remember" value="1" /> Remember your acess data!
        </div>
        <a href="index.php?remember=true" class="link" title="Forgot my Password">Forgot my password</a>
    </form>
    <?php
    }
    else
    {
    ?>
    <form name="recover" action="" method="post">
        <span class="ms in">Inform your email</span>
        <label>
            <span>Email:</span>
            <input type="text" class="radius" name="email" />
        </label>
        <input type="submit" value="Recover" name="sendRecover" class="btn" />
        <a href="index.php" class="link" title="Back">Back</a>
    </form>
    <?php
    }
    ?>
    </div><!-- //login -->
</body>
