msa.exe computer won't boot

Try doing as much of the below READ & RUN ME FIRST (down after the quote box) as possible by using a different user account if you have another one you can try. If you cannot boot in any mode ( safe or normal mode ) and you cannot run any of the READ & RUN ME there is not much we can do for you except suggest what is in the below quote box

 

Let me add some additional info to what TimW already posted. Since you have a Linux partition, you may be able to do the equivalent file copying that is mentioned in the below procedure:

Normally you would do this from the Recovery Console and it requires many steps to complete. If however you are not running the Windows OS, like when you run Linux ( or the UBCD4Win that Tim mentioned ) you can actually elimante many steps and do the backup and copying of registry keys in just about one session. I have done this many times using UBCD4Win ( but you cannot create this CD without a Windows CD ).

Basically you are just physically copying certain registry hives out of a System Restore point folder and into the place that your PC normally boots from. This is like doing a manual and partial system restore in order to see if your boot problem is caused by registry corruption.

We cannot really give you a step by step process for doing this on your system since it is outside the realm of malware removal. Also we do not have your Linux setup or know how it works or what will be accessible. You will have to try this on your own or see if anyone in the Software Forum can provide additional support.
