Rescue

Creation of a Recovery Disk:

mkbootdisk creates a boot floppy appropriate for the run­ning system. The boot disk is entirely self-contained, and includes an initial ramdisk image which loads any neces­sary SCSI modules for the system. The created boot disk looks for the root filesystem on the device suggested by /etc/fstab. The only required argument is the kernel ver­sion to put onto the boot floppy.

 # /sbin/mkbootdisk -- device <device_name> <Kernel_version>

Example:

 # /sbin/mkbootdisk --device /dev/fd0 2.4.9-e.3

To obtain the kernel version see your /etc/grub.conf file or the name of the kernel modules library directory for the information. (ls /lib/modules/ Use the directory name of the appropriate kernel. i.e. if the directory name is /lib/modules/2.4.9-34/ then use 2.4.9-34)

Useage:
Boot computer with the floppy in it's drive.

It will boot the kernel from the floppy but then try to use your hard drive. If successful, it will fully boot from your hard drive. It's Painless!!
