Well if you copied Ultima VIII folder over from your other pc, check if you copied everything so no file is missing, because the error you keep getting each time might be just because of that. Especially important that you copy the savegame folders entirely, any single file from there missing - good-bye savegame.
Otherwise just install the game on that notebook again and copy the savegame folder over, maybe that will help.

Edit: as for the no sound and/or music, try running setup/install program and set the correct parameters again. Of course I assume you play U8 in DosBox, which you absolutely should.
