I got the following error message on the screen while I tried to enter in to safe mode by hittingF8 from the keyboard in my Windows 7 system. Status: 0xc0000428. Info: Windows cannot verify the digital signature of this file c:\windows\system32\winload.exe I have also tried with repair, system restore to fix the problem but it did not helped me to solve the matter. I have also tried to renaming and replacing winload.exe with using Windows disc but it was also fruitless. Now I am requesting all of you to give me a light shed on this particular situation. Any idea will be highly appreciated. Thanks a lot in advance.
