Today I tried to install FreeBSD 11.0
FreeBSD booted from the USB stick. When mounting the install image I received error:
Mounting from ufs:/dev/ufs/FreeBSD_Install failed with error 19.
I couldn't figure out why I constantly got this error.
After tweaking bios etc. Using an USB2 port I finally gave up an though my USB stick was broken..
But then creating the second stick I found the problem.
The first time I created my memory stick like this on Mac OS X
sudo dd if="FreeBSD-11.0-RELEASE-amd64-memstick.img" of="/dev/disk2s1" bs="10240"
Look at the wrong /dev/disk2s1 path.. (that's wrong!! )
The second attempt I used the following command. (I needed tot unmount /dev/disk2s1 in DiskUtilty first
sudo dd if="FreeBSD-11.0-RELEASE-amd64-memstick.img" of=/dev/disk2 bs=1m conv=sync
Now it works :D
