Shut down during critical update

I have someones dell inspirion 560 that got shut down during a critical update It boots and the windows logo is diming in and out ,says it is starting windows but doesn't go any further I used a windows rescue disk and tried system restore and it says that the registry is corrupt..Try the command prompt and rebuilt the mbr and still nothing. Is there a bootable registry repair software I could use to try to repair this computer. Or I will take any suggestion out there on Virtual Dr.THis is a windows 7 Os

I'm guessing you tried to boot to last known good configuration also?

You can try a repair install.

Yep last know good config never worked. So I can use my windows 7 disk and use here key for windows 7 (the 1 on the sticker on the case} and that would work. Choose upgrade correct?

You need to use the same version of Win7 that is installed.

First, you need access to a standard Win7 installation DVD. Ideally, you have your original setup DVD tucked away somewhere. But if not, it’s perfectly OK to borrow one from a colleague or friend, as long as it’s the same 32- or 64-bit version as your installation. Ideally, it should also match the general type — retail disk or OEM/vendor-supplied disk — as well.

Yes, choose upgrade.

But there’s no Reinstall option listed. Instead, you have to bend the normal installation routine to your wishes by selecting the upgrade option.

A repair install is available.

Tried the repair install earlier and it found problems and tried to fix but failed because the registry was corrupt. Tried the upgrade trick but said I had to install from windows and I cant get into windows so that failed also

Got a second hdd? If yes, then install to it and then slave [be sure it is disconnected while doing the install}. After the insall, hook up this damaged hdd and you should be able to save what you would hate to lose.

no 2nd hd

And no backup I will bet, because when you do a clean install, everything on that drive will disappear.

Train suggested a Repair Install, but the reference posted is Startup Repair, Clean Install and System Restore.

A Repair Install is different and should repair your Registry.
