Mac Bootcamp Windows 7 hangs on Classpnp.sys

Hello, i have a mac with WIndows 7 running in bootcamp, i have been using bootcamp for a long time running this windows 7 installation (64 bit) and it has been error free.. until today

I had been doing some work on my osx partition of the hard drive when i then went to boot into windows i was in the other room although i could just hear my mac rebooting... when i got back i saw that the computer was blue screening and restarting :S

so i went to boot from safemode and there i noticed it was hanging on classpnp.sys

So i did some research on it and there were various solutions but none never helped me

I was directed to 'upgrade' my windows installation so upon attempting that i was told i need to run the disk from in windows.. what i cant boot -_-, I have 200GB worth of data that i NEED on the partition, I can access it from mac however i would be SO much better if i could just boot into my windows partition again,

Has anyone got any solutions/ possible solutions i can try to get this working?



Thanks in advanced

Without a ton more info I would say run a system file check if you can and a repair install if you cant.


SFC /SCANNOW Command - System File Checker

Any other options will be great
