    Remove SP1 using command prompt from recovery DVD?

    Hi,

    Upon starting my computer I'm getting error 0xc0000428, ntoskrnl.exe is missing verified signature or something like that.

    I am unable to use the startup repair from the recovery disc - I get an error called StartuprepairV2. I can not use system restore, and using cmd to copy the file from the DVD to my hard drive does not work (the file is still missing the digital signature). Bootrec doesn't fix the problem.

    I have read somewhere that if startup repair does not work, you can update your vista version as a workaround. However I can not upgrade unless I delete SP1 first, but I don't know how to do that when I can't start windows.

    Is there a way I can remove SP1 using command prompt ran from the recovery DVD? Or any other solution anyone can think of? (except for doing a clean install)

    Thanks in advance!

    Hi notsavvy, Welcome to the forum.

    Have a look here at option three; How to uninstall Windows Vista service packs as a troubleshooting step

    I hope this helps

    That's excactly what I was looking for! It didn't work for me though, since I'm missing the file needed to uninstall, but thanks for the great reply

    hi notsavvy,

    by the looks of it all you need to do is to have a clean install. 0x0000.... errors are caused by updated or unupdated drivers. using the installation dvd to repair may not help at all (based on my experiences)
