If firmware does not recognize disk as bootable, it may suggest that FAT32 in ESP is damaged or for BIOS, MBR signature is bad or like. In any case, it should not require reinstall, bootadm install-bootloader -f might be enough. If you still do want to reinstall, openindiana installer does provide option to use existing pool on very first screen (press F5). However, that option will leave some manual work for you (creating users etc). rgds, toomas _______________________________________________ openindiana-discuss mailing list openindiana-discuss@openindiana.org https://openindiana.org/mailman/listinfo/openindiana-discuss
