Laravel Error "SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'os' cannot be null"

When im input using checkbox for value windows 7 & 10 it doesn't get into the database.

But input in part <-- other -->, it can enter into database

Views Code :

<div class="form-group col-md-12">
    <label>OS :</label>
    <div class="checkbox-list">
        <label class="form-group col-md-4">
            <input id="os" name="os" type="radio" value="Windows 7">
            <span></span>
            Windows 7
        </label>
        <label class="form-group col-md-4">
            <input id="os" name="os" type="radio" class="form-group" value="Windows 10">
            <span></span>
            Windows 10
        </label>


        <!-- other -->  
        <label>                                 
            <input id="other" name="" type="radio" class="form-group" value="Other :">
            <label for="other" class="form-group">Other :</label>

            <div class="other-disclosure">
                <input type="text" name="os" id="os-other" class="form-group col-md-2" placeholder="Your OS ...">
            </div>
        </label>
        <!-- other -->

    </div>
</div>

Controller Code:

public function store(Request $request)
{
    $folderPath = public_path('assets/signature/');
    $image_parts = explode(";base64,", $request->signed);
    $image_type_aux = explode("image/", $image_parts[0]);
    $image_type = $image_type_aux[1];
    $image_base64 = base64_decode($image_parts[1]);
    $signature = uniqid() . '.'.$image_type;
    $file = $folderPath . $signature;
    file_put_contents($file, $image_base64);

    auth()->user()->Form003()->create
    ([
        'user_id' => $request->user_id,
        'os' => $request->os,
        'hardware' => implode(',', (array) $request->input('hardware', [])),
        'software' => $request->software,
        'signature' => $signature,
        'status_desc' => $request->status_desc,
        'cancel_deskripsi' => $request->cancel_deskripsi
    ]);

    // dd($request->all())
    // dd($form003);
    
    return redirect()->route('form003')->with('status', 'Success');
}

even though they are one group

How to solve this problem ?

=========================================================================== its work, i change the input name

<label>                                 
    <!-- <input id="other" name="os" type="radio" class="form-group" value="Other :">
     -->
    <input id="other" name="os" type="radio" class="form-group" type="text">
    <label for="other" class="form-group">Other :</label>

    <div class="other-disclosure">
        <input type="text" name="other" id="os-other" class="form-group col-md-2" placeholder="Isi OS Anda ...">
    </div>
</label>

but input with "other" get new problem, the value that goes into the database always "on", not based on what i write the text.

the value "on" comes from where ?
