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
