hard-drive or grub error, please help

I'm answering this question by making assumptions - as there is very little that can help me diagnose your problem - but here goes;

It seems that your harddrive has been mounted as read-only. This may be because there's a problem with your harddrive.

I suggest you try to perform a filesystem check.
Try to log in as yourself, then run;

 mount

It will list your mounted block devices and their mount points.
One or more of the block devices should start with "/dev/". For each of these, you can run:

 fsck blockdevice
(e.g. fsck /dev/sda1, if that's the name)

That may solve your problem.

I will however, urge you to boot your system with a live CD, connect an external harddrive or similar, and salvage your files - because there is a risk of the harddrive being unstable at this time - and that your files will be lost if you don't do this very soon.

I hope this helps.

Hi :)

Do you have an Ubuntu Cd that you can use as a LiveCd?

/dev/sda1 on type ext3(rw,errors=remount-ro)
proc on /proc type proc (rw)
none on /sys type sysfs(rw,noexec,nosuid,nodev)
udev on/dev type (tmpfs(re,mode=0075)
none on /dev/pts type devpts(rw,noexec,nousid,gid=5,mode=0620)
none on /dev/shm type tmps9rw,nosusid,nodev)
none on /dev/run type tmps(rw,nosusid,mode=0755)

Hi :)

Have you been able to test the new Ubuntu 10.04 before it gets officially released?
http://www.ubuntulinux.org/testing/lucid/beta1
Trying it as a LiveCd or as an extra dual/multi-boot would be ideal. Developers and everyone are keen to try to iron out any problems before 10.04 gets officially released so you might find faster & more effective answers to your bug reports which would make 10.04 work better on your system for you

Thanks and regards from
Tom :)
