I have a relative's Windows XP Home Edition on an HP laptop. Each time I boot I'm given the option to choose: Safe Mode, Safe Mode w/ Networking, Safe Mode w/ Command Prompt, Last known good config., & Start Windows normally. Now each of these options result in Windows flashing a blue screen and restarting. The BIOS is very limited so I can't ask it to not restart when an error screen appears. However, with some skill & timing I was able to use my multi-shot option on my camera to capture the blue screen. To my surprise, no error code appeared, simply the words "UNMOUNTABLE_BOOT_VOLUME". With a quick Google search I learned I could fix it with a "chkdisk /r" command with a Windows XP Installation disc; so I tried that and got the same result. So then I tried the "fixboot" command and still got the same result. So now it seems the only option is instead of pressing "R" initially, I should press ENTER as though I'm installing, agree to the EULA & THEN hit "R" to repair the system. If I have this correct, the repair procedure will look similar to the installation procedure but it won't touch any personal files, correct? Just needed to get this straight before I start messing with things. Thanks.
