Seems to be a bad cd or a bad drive. Replace both, erase the drive with DBAN (free download) and try again.
Working on a Gateway T 1629, partition portion finished (1 partition), then says it needs asms files and to insert XP sp3, which is already in. It's set to boot from cd, but it won't start over the installation. how can I just start from scratch? Is there a way to install the needed files?
