I have a similar issue (with an HP Proliant microserver). GPT on USB simply wont boot, but GPT on HDD is fine. However, I followed http://wiki.freebsd.org/RootOnZFS/ZFSBootPartition to set up an MBR on my boot-usb-stick and it worked fine. This was using a version of 8-stable of around 5th Sept 2011 (dont have svn rev at hand). > I am very reluctant to risk breaking my currently running system, the > previous boot failure caused almost two weeks of downtime. > > Does the 8.2-stable memstick image still use MBR?
