I have been trying to boot Fedora in Rescue Mode. I found the following steps:

"...To boot into rescue mode, you must be able to boot the system using one of the following methods[5]:

  • By booting the system from a boot CD-ROM or DVD.
  • By booting the system from other installation boot media, such as USB flash devices.
  • By booting the system from the Fedora installation DVD.

Once you have booted using one of the described methods, add the keyword rescue as a kernel parameter. For example, for an x86 system, type the following command at the installation boot prompt:

  linux rescue

"

So I boot from Fedora 18 Live CD and gives me Grub with two options:

  • Fedora-18-x86_64-Live-desktop.is
  • Verify and Boot Fedora-18-x86_64-Live-desktop.is

Then it tell me if I want command line to type c, so I type c and then type linux rescue but nothing happens, the command does not exist. What am I doing wrong?

If I select the option 1, then I boot into Live Desktop. What exactly do I have to do? I am confused.

Thanks

I was able to figure it out. To enter rescue mode, in grub type e then move cursor at the end of the line that begins with linuxefi and type rescue, press enter and then (if I remember correctly F10) to boot the computer.

Weird. I've never known live media to have a rescue mode. What did the above give you finally?

yeah, Live media don't have rescue mode or can't find anyway to boot in rescue mode with a Live iso

Add the parameter "3" to the kernel/boot/grub command line. This will bring you into "runlevel 3" - i.e. "Single User Mode" - no GUI

runlevel 3 is multiuser , 1 and runlevel 1 is the "Single User Mode"

There is no rescue mode, but you can reinstall grub from the live session, see http://forums.fedoraforum.org/showthr...

in particular post #4 where stoat describes the various methods very clearly

mount /dev/mapper/VolGroup-lv_root /mnt/
mount /dev/sda2 /mnt/boot
grub-install --root-directory=/mnt/ /dev/sda

It says "install media", not "live media" as far as I remember. Live media do not have a rescue mode. Please download the install dvd.

I forgot to emphasize, like was wrote in other answer, that live cd don't have rescue mode, just boot.iso and install dvd

To do Fedora 20 rescue mode from usb stick: download boot.iso

http://mirrors.eu.kernel.org/fedora/r... or http://mirrors.eu.kernel.org/fedora/r...

we can put boot.iso on a usb stick , in same way that we put live images, describe in USB Booting : usb must be on vfat or else format usb with:

# mkfs.vfat /dev/sdb1.

# /usr/bin/livecd-iso-to-disk boot.iso /dev/sdb1

also you may test is USB boot with :

qemu-system-i386 -hda /dev/sdb -boot a
