>From the bootloader you can use the 'machine diskinfo' command to list the disks that are recognised, (by the bios). This will list the device name, (that the bootloader uses, not the same as what the running kernel will see it as), and the size of the disk, (and other information). Unless you have two identical disks, it should be obvious from the size field which device name corresponds to the disk that you installed OpenBSD on. Then you should be able to boot the installed kernel with: boot hd8a:/bsd where '8' is replaced with whatever the correct number is. If this does not boot the kernel, then you can find out more information by doing: boot hd8a:/bsd.rd If this boots into the installer then your installation was partially successful but for some reason did not write the kernel at the expected location in the filesystem. The easiest solution here would be to re-install rather than try to work out what happened. As a side note, if you installed to an encrypted volume, (I.E. when the installer asked, 'Encrypt the root disk with a passphrase or keydisk', you selected anything other than 'no'), then your system would need to boot from an 'sr' device rather than 'hd'. There are a few failure modes that can cause the bootloader to be configured incorrectly and instead of trying the correct, (usually sr0a), device, hit hd0a instead. On a running system, this can be corrected by booting by some other means and running installboot with the correct parameters, but if this is a fresh install and you are not familiar with OpenBSD then re-installing from scratch is probably easier.
