Been lurking around these forums for a little while and I have reallly appreciated all the help. I am dualbooting my system, Windows XP and Ubuntu 10.4. All was working quite well, when one day, I rebooted from within windows, and when I tried to come back in, Windows didn't work. In GPartEd, the windows Partition shows for Filesystem "unknown". I am wondering if it is just the MBR that is messed up or if I have bigger problems. Thankfully I had most of the data backedup, but I would like to recover it if possible. Any suggestions?
