I'll start off why i need help.
I tried to make a custom login screen for Windows XP, but it backfired and now i can't login. I made a backup of a file that i need to replace in order to login. Unfortunately, i am unable to login because of the messed up file i tried to make. So anyways I poped in my goot ol' Ubunto Live CD and looked around on how to mount my windows hard drive. I eventually did it, but was unable to have writing permisson, it was just read-only. So what i am asking is, how can I mount my Windows hard drive so that i am able to read and write to it? I am a huge noob here so a detailed response would be much appreciated
