Recently I installed a faulty security update (2823324) released by Microsoft http://support.microsoft.com/kb/2839011 . My computer is constantly getting blue screen and restarting. I have tried each and every solution in that kb article.
I tried startup repair without success. I cannnot even boot into safe mode. And I don't have a system restore point. I tried the same after booting from a win 7 iso loaded onto a usb. I tried startup repair and system restore. And when I want to try the command line solution listed in that article, I get the error that dism is not found.
I found an article about dism http://technet.microsoft.com/en-us/library/hh825176.aspx in microsoft website. It does have a section on , how to copy dism into another computer. But the thing is, I do not know how to copy it using command line when booting from a windows 7 iso in a usb.
Note: I have windows 7 home premium service pack 1 installed in my laptop and in my recovery usb. Note2: The laptop is a Dell laptop and I had previously deleted the system recovery partition that usually is present in laptops that ships with windows, because I needed to use that space.
