If you absolutely can't do a repair install and you can't boot your system at all, then I'd suspect you either have a serious hardware failure or your Windows 7 installation is somehow flawed. Since you're so fresh into this install, if it were me, I'd wipe the drive and reinstall Windows 7. Once you get a running, tweaked and activated system, make a system image so if this happens again you can restore the image to a known functioning point and not have to reinstall the entire system from scratch. After that, start installing updates. Do the security ones first and the other ones later in stages. The idea is to get a functioning activated secure system and be able to go back to it if the whole thing blows up on you again.
If it's the loader then just do the following. Code: ########################################################################## # 1 - Recovery ########################################################################## Is Windows failing to boot after you installed the loader? Just do the following. * Boot up the PC from your Windows installation disk * Press and hold SHIFT and then press F10 * Input "bootsect.exe /nt60 SYS /force" (without quotes) * Restart the PC Note: If the above doesn't fix your boot issue then use the command "bootsect.exe /nt60 ALL /force" instead. Just make sure you remove all USB flash drives before you use the command. I'm doubting it being the loader because if it worked the first time then it should work every other time too. However, if this does get you booting again then reinstall the loader with the legacy option toggled.
Well you cannot keep it running for ever you need to shut down sometime, you need to get system running correctly.
The default setting for fault response is to reboot. No warning ... just a reboot. And you have to deselect the option in order to stop the instant restarting. Of course, when you do that, the fault will give you a BSoD but that at least will give you clues as to your problem. Like urie said, you just gonna run forever in fear and never shutdown? Never happen, we all shut down sooner or later and given this is a new installation, you're going to be way ahead of the game solving your problem now.
