There you have MBR + VTOC in Solaris2 partition - we can only boot with BIOS mode with this setup (no MBR EFI partition (type code 239).

This one is interesting - only partition 1 and 3 are known, it should not affect us, its just interesting (we should see illumos ZFS there).

Much more interesting are partition sizes. If p3 is really windows, then p2 or p4 do not have enough space to store rpool — ould expect to see minimum some 16GB or so (/ file system should take some 5+ GB of space).

And this operation made all the disks in rpool unbootable on this system. I should probably have run"# bootadm install-bootloader -Mf -P rpool " to force installation of a "legacy" MDB boot.

However, if I type zpool list on that, I do not see any pool even if I boot it with reconfigure. How can I install the booting stuff on the internal disk of the system from an openidiana running on the installation dvd. Some versions of bootadm allow specifying the device on which to install the booting stuff, but not the bootdm on openindiana.

If you have dual/multiboot setupand have this binary from some other OS, you need to make backup of it first, then after bootloader install/update,you need to create alternate locationfor it, like <ESP>/boot/illumos/ and create UEFIboot manager configuration in firmware setup and restore the original bootx64.efi.

The need to use the GUID is a known old bug that was supposed to have been fixed. I do not know why I had the use the full pathname of the new disk. Maybe it is due to the fact that the new disk was connected to a usb adaptor.
