I'm working on a Dell Dimension 8200. There was a setup password someone added but the user didn't know. Initially, I unplugged everything, removed the Cmos battery and pressed the power button to drain the system. After replacing it, the pasword was still there. I went to dell's site and they say to remove the Pswd jumper, start the system, unplug it and reinstall it. Then, I went into setup and made sure the settings (like the hard drive) are correct.
Now when it boots, I receive this error: Dell's Disk Monitoring System that Drive 0 on the Primary EIDE controller is is operating outside it's normal specifications. it's advisable to immediately backup your data and replace your hard disk.
I tried continuing in regular and safe move but received a BSOD - Unmountable_Boot_Volume
The system was running before the password was added.
