How does one "manually repair the partition table," and what phase of the kitchen build should this be done during? I close buildos and run buildit.bat, and eventually nbmerge crashes, but when it closes, buildit continues to run, and deletes my temp folder if I do not exit before it finishes, so I have to rerun buildos and choose my OEMs again.
So if somebody would just simply explain to me what it means to repair the partition table..
