Can I rename a system file from my Linux
 

Can I rename a system file from my Linux, I have renamed one system file mistakenly and now I can’t load windows, can I rename the file or not?

Do you have access to your Windows partition from Linux, or is this where the actual problem is?

yes i have it mounted

I dont know understand. If u changed the file name on the windows side of the disk, why cant you just rename it back? You can still access it through linux in /dev/ .. right?

i believe you can rename whatever you like if you've got the partition mounted. say you've got your windows drive mounted to /mnt/windows :

cd /mnt/windows
mv file.doc newfile.doc

that should do it...although a thought occurs to me, which is that ntfs might not have write support. anyone know where this stands?
