No. Stop. DO NOT USE sdb1. DO NOT USE fdisk.

The device name on that Linux system is sdb. No "1".  Just sdb. sdb is 
the disk, sdb1 is the first partition on that disk.

Of course, writing that image to /dev/sdb will overwrite whatever is 
already there. Be careful.

On Linux, use either 1M (capital "M") or 1048576, it does not matter. 
They are the same thing.  One is just easier to type.

Do not try to mount it. There is no point. Boot (start the computer) 
from that disk. It is the FreeBSD installer.

I'm sorry, I do not understand the remaining points (#3-#8).  Or what 
you are trying to accomplish, for that matter.
