the installation never freezes or halts. I go through the entire install process w/o any issues. computer reboots when done and then gives error when it trys to boot the Operating system (either XP or Ubuntu). I should note that I am not trying to share, if I switch which OS im using, I re-format and start over... I' m a bit novis for all the dual load OS stuff... LOL. one more thought, I don't think it is the HDD b/c Ubuntu will not run from the CD either. Something about the configuration of something is stopping the computer from being able to run an OS, but is working well enough to allow the computer to function insofar as loading a bootable disk, editing bios and installing the OS all work... and seems to be stable. Wierdest thing ive seen yet!
