During an automatic update from Microsoft last night the battery fell out of my daughters laptop. This morning, nothing will open. Have tried safe mode but even that won't open windows. After a lot of digging it says on the recovery management that there is a bad patch which presumably if the failed update. I have tried system restore and for the computer to repair itself but no go. I would hope that if I could install said update maybe it would be ok. I can only get any access to the contents via an external CD shich has a windows 7 rescue disc to allow you to boot up the startup recovery. I can access notepad and command prompt. Is there anyone who can help please?
