Hello, Kris. This is normal behaviour if your /etc/fstab has an entry like this: > UUID=... / ext3 relatime,errors=remount-ro 0 1 The mount option "errors=remount-ro" tells the kernel to remount the '/' filesystem read-only if any errors occur. This is to prevent a chain reaction of corruption in which you might lose the entire filesystem! Best advice is to reboot from the Ubuntu 'live' CD, and salvage anything precious from the '/' filesystem on the hard disk while you can. Then, after that, run filesystem diagnostics from the 'live' CD, using e.g.: sudo -i fsck /dev/sda1 # or whatever partition your '/' filesystem is on. It might also be a good idea to try: badblocks -sp1 /dev/sda Good luck!
