..tried checking the connections to the hard drive.. If a laptop, reseat the hard drive.. If a desktop, reseat all the cables and plugs.. If that doesn't help, try placing a bootable disc such as the Recovery Discs into the DVD/CD drive and restarting the computer? At his point, since it won't boot to either "normal" Windows or Safe Mode, the option is to attempt a format and reinstall of everything back to it's original state.. If such a format and reinstall doesn't work, then the hard drive is probably dead and needs to be replaced.
Hope this helps.
I have a Compaq Presario 6000 running Windows XP that will not boot. I can get to BIOS by hitting F1. When I try to boot in safe mode, nothing happens when I select which operating system to boot.
During the normal boot cycle, it freezes after the hard drive boots (right before the Window XP screen). In the past I would get a "Disk Boot Failure" error, but now I don't get any messages. Any suggestions?
