your txtsetup has a boatload of files in it that are not DriverPacks nor ms...
what did you use to add drivers / themes / cursors ect... with?
start with a CLEAN source... you did not start clean...
A normal txtsetup is around 6k lines yours is over 15k lines that is a HUGE amount of garbage.
Ten thousand unexplained lines ?
since you are not adding mass storage only two lines are added to txtsetup.
and these two lines do not cause issues, we have been adding them for almost five years
they are exposing a preexisting issue of some kind.
if you use nLite or RVM, ect... you need to mention it.
also DriverPacks must be the very last step in your process.
i am going to guess you did DriverPacks first then ____. That will fail...
Instead of me having to guess please tell us your process step by step...
