When I download, dd to usb and tries to boot from the stick I only get the error message: No System Found. There is nothing wrong with the download or the stick since it boots fine on another system. I can boot FreeBSD 10.1 memory stick. Test made with FreeBSD-10.1-RELEASE-amd64-memstick. Various linux distribution all works fine. I currently use Ubuntu Mate Edition. FreeBSD 11 does not boot. I have tried with FreeBSD-11.0-CURRENT-amd64-20150309-r279813-memstick.img. PC-BSD 11 does not boot. I have tried with PCBSD11.0-CURRENTMAR2015-03-07-2015-x64-DVD-USB, and also the February version. My guess is that the BIOS/UEFI on my laptop is some kind of edge case. The laptop is a Sony Vaio SVP132A1CM. If you want me to try different solutions, please use version 11. Since the 10-series does not support modern Intel chipsets and I will be stranded without wifi or graphics support.
If this is still an issue please test with a modern FreeBSD and reopen.
