You still have grub installed in the MBR of the external disk. You need to install a new MBR on the external disk. Boot the OpenBSD install media again to run fdisk. Carefully read the fdisk(8) man page, you want the -u option. http://www.openbsd.org/cgi-bin/man.cgi?query=fdisk&apropos=0&sektion=0&manpath=OpenBSD+Current&arch=i386&format=html This man page is also available inside the install media, see the 'manual' command inside fdisk. If it still does not boot, make sure you have the partition on the external disk that OpenBSD is installed in is flagged as active. Again, refer to the fdisk man page on how to do this. > my boot processes from the first hard drive are still successful though. Make sure to know what you are doing. Do not run fdisk on the wrong drive or you might have a problem booting the first drive, too. See also http://openbsd.org/faq/faq3.html#FirstSys If this is your first OpenBSD install you might want to try a simpler setup first, with an internal drive instead of an external one. Good luck, Stefan
