Last night after doing a standard reboot my machine will no longer boot into normal mode. Below are my observations. * System appears to boot normally reaching the XP Pro screen * Eventually the progress bar stops moving * Select safe mode or normal mode screen appears * If Safe is selected system will boot * Rebooting from safe sends machine into boot loop * If normal is selected then a quick blue screen flashes * System continues to reboot I am thinking that I may have to recover (repair) from the OEM XP CD. Not really sure if this is the correct direction to move in. My other thought is trying to use the Ultimate Boot Disk in order to run a dskchk. Thoughts and ideas are greatly appreciated. Thanks.
