I know this problem has been talked about before but I need to ask some questions about it: Today I downloaded and installed (straight from windows) Internet Explorer 8 to run a web program for a class I'm taking. After it installed, it wanted to reboot, like normal so I rebooted and when it restarted I got BOOT DISK FAILURE, INSERT SYSTEM DISK AND PRESS ENTER. After some freaking out, not finding my OS disk, trying to switch the boot priority in bios, and resetting default settings, nothing has worked. I tried to download the diagnostic check for my hdd, and burn it to a disk using another comp but the file wont move. So there's that. Also, how am I supposed to run a diagnostic check without getting into windows? I noticed one guy on a thread had managed to get into his os somehow, can you elaborate??? I would greatly appreciate any help.
