I had instant start with 2.1 and very slow start (more than 2 minutes!) with 2.1.2 at the same configuration. BCD files - in attach. There's no any errors in it, "Mandriva Linux" item is created by EasyBCD itself (but slow start was before).
No, it's not first access time. It always inserted in USB socket and continually used. And EasyBCD starts 2 minutes EVERY time, with no difference in 2 or 48 hours after OS starting (with inserted USB flash). Today is 3 days after starting (and corresponding USB insertion) - same behaviour.
