<p>In your examples I honestly can't see any essential distinction, they are interchangeable here.</p>

<p>没 is not a verb because there is no action in 没，nothing.</p>

<p>不 is not a verb neither because there is no action in 不，not.</p>

<p>The verb are 起 and 选:</p>

<p>已经九点了，你怎么还不<strong>起</strong>床？ (起 is the verb here, it means "get up")</p>

<p>你怎么不<strong>选</strong>一个更好的作文题？(选 is the verb here, it means "choose")</p>

I'm no questioning whether 没 or 不 are verbs or not.

There's a "difference between 不 and 没" question here chinese.stackexchange.com/questions/6586/…  The answer stated the basic difference between 不 and 没 on their own.  However, 没+V is commonly being used in place of 不+V, especially in past tense as songyuanyao stated

According to the book "Modern Chinese Grammar" (<http://m.sanmin.com.tw/product/index/000225652>), we can roughly distinguish:

1. 不: this word is a negation that comes with the speaker's subjective feeling, which means that the speaker might think the other should have done something (for example in the first sentence, you should have already got up)
2. 没: this word, however, is a negation which is more or less objective. That is to say, the fact that the other person did not wake up is noted.

To sum up, in both sentences, the contexts show very strong meanings that both speakers did not agree with what the others have not done, and therefore the negation word "不" was used.

As a native speaker, I feel that using the negation word "不" is usually more powerful and that implies the relation with the other is more close. Hope this answer can give you some clues.

In your examples I honestly can't see any essential distinction, they are interchangeable here.

Speaking about the tense, 没 may intend to express a very weak comparison between the past and the present(before you didn't, now you still haven't), so I will naturally translate it using a prefect tense, but basically either past tense or perfect tense is ok for them both.

没 is not a verb because there is no action in 没，nothing.

不 is not a verb neither because there is no action in 不，not.

The verb are 起 and 选:

已经九点了，你怎么还不**起**床？ (起 is the verb here, it means "get up")

你怎么不**选**一个更好的作文题？(选 is the verb here, it means "choose")
