During the setup, I had got a problem saying, "Setup needs some files (it couldn't find agt0407._dl which was there). Please insert the XP cd", even when I the cd was inserted already. So thinking of it to b a problem with the cd, I restarted PC with the same cd, re-written wid same version (SP3). Then I started getting an error saying, "Fatal Error. An error has been encountered that has prevented Setup from continuing." It further showed log file with "Failed to install product catalog AND XP signature is invalid." Then on searching google, I found a forum on microsoft saying the reason would be incomplete deletion of 'catroot2' folder. I followed their solution. But the next time I restarted, I got this problem.
The message popping and vanishing quickly and then reboot.
I read garmanma's reply above, but couldn't understand HOW to reformat at this stage when the setup restarts with that error message each time I turn on PC. I hope there would be a solution asap.
