Is there some specific steps you do that will cause the crash, or really clicking Save anywhere will cause this behaviour?
Here are some things you can try:
- Redownload the ISO
- Try the USB on anoher machine and see if you get the same issues
- (long shot) Try another USB drive
- (long shot) Connect a monitor to the machine, and hit CTRL-F1 to get to the console. Now make any change to the settings and see if any errors turn up?
