Sentence: I am going to start the server in five minutes OR within five minutes?

Hi,

“Probably he may come in the next week”
" I am going to start the server in five minutes" or “within five minutes”

Does the above sentences contain any grammatical mistakes?

If “Probably” word is used in the sentence , Does the word “may” is need in the sentence or not ?

Please clarify my doubts with an examples.

No, may and probably overlap in meaning. These are correct:

He will probably /He may come in the next week.
I am going to start the server in / within five minutes. – The grammar is OK, but ‘within’ is unusual here unless time is of the essence.
.

‘Within’ would set 5 minutes as the maximum, whereas ‘in’ would set 5 minutes as the base point, so that you could be expected to take around 5 minutes to start the server, give or take a minute or so.
