Please follow the steps in below link:

for any issues during mounting like:

fsck.ext3: Unable to resolve 'LABEL=/boot'
fsck.ext3: Unable to resolve 'LABEL=/home'

*** An error occurred during the file system check.
*** Dropping you to a shell; the system will reboot
*** when you leave the shell.
Give root password for maintenance

From maintainence, 

A few useful commands here; just in brief, enough as keywords for you to go googling for details, or check the man pages.

fdisk -l	(to find out the partitions on the disks)
e2label/dev/sda1	(find out or write the label for a partition. in this case, partition 1 of /dev/sda. of course, IDE disks will show as /dev/hda etc)
mount -o remount,rw /	(remount a readonly filesystem readwrite so changes can be made, especially to files like /etc/shadow, /etc/fstab, /boot/grub/menu.lst etc)
passwd	(change the root password if you have forgotten)

Sometimes it is useful to go into single user mode, especially if the server hangs when it tries to bring up the network. To do so, when grub comes up, press the up or down arrow keys, select one of the kernel, press 'e' for edit, and append "single" to the end of the line. come out of the editing by pressing enter, and press 'b' for boot. Also useful when you have SCSI RAID drivers, other than provided on the installation disk, on the server. So you really want the server to boot up with the drivers.

Usually, if you have access to the console, it is easy to boot up using CD. example, the server cd of centos. key in linux rescue at the prompt, and you will get a nice environment to use for fixing your server.
