>>> This disk is windows only. I was the only one when I bought the computer.I never modified its microsoft sriucture. I added the second disk to have openindiana. Originally I had a 500GB ssd for openindiana but it crashed (probably too many bad blocks) and I replaced it temporarily with a 120GB ssd I had on a shelf. There I had to reinstall everything from distro and back-ups because the old 500GB disk was unusable. Now I bought a new 1TB disk. I connected it as external usb disk and made it a mirror of the 120 GB One but I made the error of run bootadm installboot without -M so it garbled the boot structure of both disks. Now I try to fix the boot structure, first of the 120Gb then of the 1TB

As long as it has usable pool on it, yes., it should be possible. If you boot usb, you can still check if loader can see pool on this 1TB disk (lsdev -v), if it does, you can set currdev=zfs:rpool/ROOT/dataset: and boot (and then run booadm or installboot).

Or you can boot OS up from usb key; then check zpool import output, if the pool is indeed there; then use zpool import -N rpool (import, but do not mount anything), then either use bootadm or installboot to reinstall bootblocks.

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.
