Disable the fsck on boot

1. Boot the system from boot disc 1 or an ISO image of the installation media
2. Once the system has successfully booted from the ISO image and the Red Hat Enterprise Linux boot screen will appears, type: "linux rescue" without the quotes, and hit enter at the prompt.
3. Select "Continue" when prompted to allow the rescue environment to mount Red Hat Enterprise Linux installation under /mnt/sysimage directory.
4. Type "chroot /mnt/sysimage"
5. Then edit /etc/fstab
6. In this file, in the very last column for each mount point, there is a number.  Changing this number to a 0 (zero) will make it so that it does not try to fsck that mount point on boot.
7. Save the file
8. Reboot or CTRL+D
