question
grammar usage
Can the particle "no" の be used at the beginning of the sentence?
Nope.

One minor exception would be “finishing someone else’s sentence”, like

> 「やったのは誰？太郎？」  
>  「…の弟、ね」  
>  “ Who did it? Taro?”  
>  “...’s little brother, actually.”

But this is really only possible when the last word of the person you are
speaking to is the head of your sentence. It feels less like a grammatical
thing and more like a conversational trick.

answer
The short answer is no.

While you can leave off the subject of a sentence if it is understood, the
same cannot be done this grammatical structure.

の is a particle that is formed by the following structures

> Noun の Noun  
>  (watashi no hon)

or

> Noun (particle) の Noun  
> (Amerika kara no hon).

Often, you will see it in connection with noun phrases, which makes the usage
very versatile, but not in the way you ask.

answer
As others have said, the answer is no. However, you _could_ leave the
**subject** off the end of the sentence _if_ it's well understood within the
sentence context.

> × わたしの（です）。 → No context
>
> ○ A: 誰の本ですか？  
>     B: わたしの（です） → It's understood that the book is the subject
