I've installed it on this computer before, but I just changed my hard drive, and attempted to install it on here. After install, when I reboot, the system just hangs, and I can't even use the reset button. The power button is even disabled. I have to hold it down for 6 seconds instead of an instant power down(as usual). Settings Windows back to the last know good configuration at least prevents an OS reinstall. But Returnil will not work. I even tried uninstalling my anti-virus, Sandboxie, Comodo, everything that starts with the system. The exact same thing happens. It will not boot to Windows. I'm on 32bit XP SP3(same OS[though different install] as on my old hard drive). Any ideas?
