That phrase doesn't seem to make sense, but I have a couple of guesses.
As Mari-Lou A said, booting can mean being thrown-out of a place or event, but that is usually in the form of "booted him out of", not "booting him up to". In can also mean being fired, usually in the form of "booted him". It can also mean a promotion, usually in the form of "booted him up to".
"These guys" can refer to inanimate objects as well as people--a form of personification. For example, you could refer to stack exchange questions and say "These guys are a lot more difficult to answer that I thought they would be."
If guys is used in that sense, booting might refer to starting a computer, a shortening of the word "bootstrapping". Or it might mean upgrading, a variation on the promotion usage, particularity if it was "from" instead of "out of".
However, without more information, these are all guesses--but perhaps still useful information.
