I tried to update my windows security and it failed. Since then my system won't boot to Windows and I get the blue screen of death. It has a stop code of Ox0000008E. It suggests I try to boot from the startup disc but Windows came loaded when I purchased my laptop. (Dell Studio 1555) Is there a way of obtaining a startup disc for my laptop or is there someone out there who can tell me how to fix the problem? I can only boot up in safe mode.
