I'm a little stuck... Click here to teach me more about this clue!

'start again' is the definition.
(I've seen this before)

I can't explain the remainder of the clue.

(Other definitions for reboot that I've seen before include "Start (computer) again" , "Start up a computer's initial program again" , "Start notebook again" , "Re-start up a computer's initial program" , "Recover from crash" .)

I've seen this clue in The Irish Times.
