troubles at booting

Hi folks, I hope someone out there is able to help me with my problem ;)Since yesterday i am not really able to boot into my Kubuntu any more.During the booting, at mounting the HD i think he quits with the errormsg "Unable to resolve UUID="...." exit status 8The UUID he can resolve is the partition that is mounted as home, i changed the fstab to prevent him from mouting it, now i come to the logonscreen but after logging on i get the errormsg "could not start kstartupconfig, check your installation"On the home partition i tryed to do a fsck which was quited with an errormessage telling me that he can't read the superblock...Any hints?Thnx in advance.
