Reboot is used to refer to card in vertical position or the action of switching a card from horizontal position (a.k.a. Sleep) into the vertical position, basically it is similar to untap in MTG or stand in CFV.

On the other hand, Boot is one of the classification of ability. It is the kind of ability that must be manually activated by the controller, if you are familiar with CFV then it is pretty much similar to [ACT] ability.

P.S.: Maybe you'll want to check the Playing Manual once again in order to familiarize yourself with the game terms. ;)
