When powered up, my computer displays a screen that basically says that windows did not successfully start up and that it may be because of a recent software or hardware change. The only change that I made recently was to install the bundled software that came with an MP3 player, that can't be it. It then gives me the option to start up in safe mode(also with networking or with command prompt), in normal mode or using the last known good configuration. None of these work, it just repeats the cycle, I can't even get to the command prompt screen. Is there any way to repair this without losing data? I have an XP cd, but it was not used for the current installation as it came preloaded. Any help will be appreciated.
