To boot your system in rescue mode, boot from a Red Hat Linux boot disk or the Red Hat Linux
CD-ROM #1, and enter the following command at the installation boot prompt:
boot: linux rescue You can get to the installation boot prompt in one of these ways:
. By booting your system from an installation boot diskette made from the boot.img image. This
method requires that the Red Hat Linux CD-ROM #1 be inserted as the rescue image or that the
rescue image be on the hard drive as an ISO image. 1
. By booting your system from the Red Hat Linux CD-ROM #1.
. By booting from a network disk made from the bootnet.img or PCMCIA boot disk made from
pcmcia.img. You can only do this if your network connection is working. You will need to identify
the network host and transfer type. For an explanation of how to specify this information, refer to the Ofcial Red Hat Linux Installation Guide.
After booting off a boot disk or Red Hat Linux CD-ROM #1 and providing a valid rescue image, you
will see the following message:
The rescue environment will now attempt to find your Red Hat
Linux installation and mount it under the directory
/mnt/sysimage. You can then make any changes required to your
system. If you want to proceed with this step choose
'Continue'. You can also choose to mount your filesystem
read-only instead of read-write by choosing 'Read-only'.
If for some reason this process fails you can choose 'Skip'
and this step will be skipped and you will go directly to a
command shell.
If you select Continue, it will attempt to mount your lesystem under the directory /mnt/sysimage.
If it fails to mount a partition, it will notify you. If you select Read-Only, it will attempt to mount
your lesystem under the directory /mnt/sysimage, but in read-only mode. If you select Skip, your
lesystem will not be mounted. Choose Skip if you think your lesystem is corrupted.
Once you have your system in rescue mode, a prompt appears on VC (virtual console) 1 and VC 2
(use the [Ctrl]-[Alt]-[F1] key combination to access VC 1 and [Ctrl]-[Alt]-[F2] to access VC 2):
sh-2.05a#
If you selected Continue to mount your partitions automatically and they were mounted successfully,
you are in single-user mode.
To mount a Linux partition manually inside rescue mode, create a directory such as /foo, and type the following command:
mount -t ext3 /dev/hda5 /foo
In the above command, /foo is a directory that you have created and /dev/hda5 is the partition you want to mount. If the partition is of type ext2, replace ext3 with ext2.
If you do not know the names of your partitions, use the following command to list them:
fdisk -l
