<tsoome> ok, in that case open terminal, from there, zpool import -N rpool
<tsoome> then bootadm install-bootloader -P rpool
<tsoome> you may want to use also -M to get MBR updated
<tsoome> zpool import -N rpool; bootadm install-bootloader -MP rpool

<mystified_> cannot import 'rpool': pool may be in use from other system, it was last accessed by  (hostid: 0x8bf238) on Sun Feb 19 07:08:01 2017

<tsoome> ah then zpool import -fN rpool

<tsoome> bootadm install-bootloader -vMP rpool
<tsoome> -v is verbose
<tsoome> -M is update MBR

<mystified_> bootblock version installed on /dev/rdsk/c4d0s0 is more recent or identical
<mystified_> Use -F to override

<tsoome> bootadm install-bootloader -fvMP rpool
<tsoome> -f will add force for bootadm

<mystified_> bootblock written for /dev/rdsk/c4d0s0, 219 sectors starting at 1024 (abs 65284) stage1 written to slice 1 sector 0 (abs 16065) stage1 written to master boot sector

<tsoome> zpool export rpool
<tsoome> and reboot


you want to re-run: bootadm install-bootloader -fvM
<tsoome> and reboot to verify it is atill ok.

you have, but the issue is related to MBR boot code setup
