I decided to recreate my USB with the most recent anyboot image R1A2 I could find. Thanks to the release they were pretty hard to find on haiku-files.org but me and my friend google resolved this issue. (http://haiku-files.org/anyboot/index.php?show=all) I downloaded haiku-nightly-r41539-x86gcc2-anyboot.tar.xz and used this to put on my USB-stick. I tested the USB-stick and it works without any fail-safemode needed. Regards, Arnold
