700mb CDR

I just thought of a snag you may run into. Your Dell uses winXP, right? Do you have any CD-burning software installed? Windows XP has some built into the windows media playerm, but it is not a full featured CD-burning suite, so you won't be able to burn an iso with that. It might be that you'll need to get a copy of Nero, Alcohol 120%, or Roxio EZ-CD installed on XP before you canm burn the iso. There's probably a free app out there somewhere, I just can't think of a name just now...
