No Such File Or Directory While Trying To Open Abl

dear all,Yesterday, I modified the /etc/fstab file in order to mount my usb thumb driver atomaticly. dev is sba1 and the mount point is /mnt/usb. I cannot remember what other parameters had been used, as I got something emegene to do.I just use "halt -n" comman to shutdown the PC.Today, I found that it cannot boot into the system.when it checking root filesystem:fsck.ext3:ABEL=/:The superblock could not be read or does not describled a coorect ext2 file system. If the device is valid and it realy contains an ext2 filesystem (and not swap or ufs or something else)then the superblock is corrupt and u might try running e2fsck with an alternate superblock .e2fsck -b 8193NO SUCH FILE OR DIRECTORY WHILE TRYING TO OPEN ABLE=/System info:readhat AS 3.0root(0,1)kernel /boot/Vmlinuz-2.4.21-4.EL ro root=LABEEL=/initrd /boot/initrd-2.4.21-4-EL.imgP.S. Just a LINUX os is installed in this pc.Help...what should I do now??? don;t want to format the hardisk and reinstall the whole system.

Hi...You probably missed one letter in boot manager configuration or drives changed and you doesn't inform boot manager about that changes... (from what you said it looks like it is "L"...) or something else - right now there can be many reasons also wrong fstab... try to catch all files you edited... if you edited it with some reasonable good editor (gedit, kedit, almost anything but don't know if all) you should have old fstab on hard drive under name f.e. fstab~ and if you delete old fstab and reneme that copy you should have working system again... You probaby would need to get into shell - you can do this using rescue cd (if your distibution have one) or download any floppy mini-distribution that have only basics... you don't even need text editor - you can cat old and new file, then rm old and mv new... also you can start your computer from some live linux like knopix or slax... If you have Boot manager you probably can also try to run computer in single user mode... Hope you would get it running soon and don't loose your data... good luck...

Yup from your output it seems exactly like what Giniu said - some sort of misnomer.. as in wrongly typed label or folder in the bootmanager file. Your only way out is to boot in console mode using rescue disks or using a live-cd if that came along with your distro.

I booted the system by using single mode，when it reach fsck, I press ctrl＋c, then I can login as root.When I can edit /etc/fstab file. However, it does not allow me to save it. The system said I don;t have write premission.Then I applied "chmod 700" to /etc/fstab, but still cannot save.chown root.root, still does not work.obvisorly, /etc/fstab cannot be deleted as well.as the reusle, fstab~ cannot be rename to fstab....>_<now my question is how to get the write permission of fstab???

strange, everything should be writeable as root.

maybe the partiton was mounted read only ?
remount root as read / write with the mount command.

mount /dev/hdXN / -o remount,rw

Problem fixed..download a live cd..boot into rescue mode....remount the /dev/hda1then modified /etc/fstabjust change ABEEL=/ to LABEEL=/man..just a little L.... it took me about 2 days to solve thsi problem..>_<Guys..thanks for your help.
