How did you manage to put two (!) images on one and the same boot media? This looks wrong. If you prepare a FreeBSD boot USB stick with the memstick image, using dd, this stick will boot FreeBSD (_from_ the stick), nothing else. > 1. fdisk -l ...dev/sdb1 c W95 FAT32 (LBA) That looks wrong as well. A FreeBSD memstich, if created properly, does not look like a FAT32 file system. > 2.mkdir /home/user/mnt > > 3.mount -f pcfs /dev/sdb1 /home/user/mnt That shouldn't even be possible with a properly written FreeBSD image. From "man mount_pcfs" (Solaris): mount attaches an MS-DOS file system (pcfs) to the file system hierarchy at the mount_point, which is the pathname of a directory. If mount_point has any contents prior to the mount operation, these are hidden until the file system is unmounted. I'm not sure what you did (successfully?) mount, but it doesn't really look like anything FreeBSD-related... > or ubuntu 16.04 not compatible I cannot imagine that it should be impossible to create a FreeBSD USB stick from Ubuntu. You don't need more than dd and the memstick image. CHeck your process again, compare to the online documentation. > 4.more /dev/sdb1 > > some great file started with > > Loading keymap > > oadertoo large > > Non-system disk > > Press any key to reboot > > folloving text not readable It is _not_ a text file, so you cannot display it with the "more" pager. You're literally reading the stick, and at its beginning, there is binary (!) boot code, which you cannot actually read. :-) Instead, after mounting, you should have issued the command # ls /home/user/mnt so you can check what's on the media - on a file system level, not on "bare bits & bytes". ;-) > what is false ? must be cleaned for second dd attempt ? In best case, remaining data is overwritten by dd, so there is no need to remove anything prior to a new attempt. > or problem is multiboot scenario ? It shouldn't be. Booting from USB should have priority over whatever is stored on the computer's hard disk. Again, make sure that your PC's BIOS/UEFI has booting from USB enabled. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... -- http://www.fastmail.com - The professional email service
