I need to change some configuration files in windows because it won't boot anymore. I tryed using the live cd to correct the problem but when I mount the hard drive I can't write to it because it says that it is a READ ONLY FILE SYSTEM..... I tryed using the following commands:

>su
#mount -o dev /mnt/hda1
#cd /mnt/hda1
#mkdir ANYTHING

But I can't write to the HD, please its really important for me to be able to write a file to my windows partition. I only have windows on this computer and i am using the live cd to recover windows.... thanks
