Linux distribution
SystemRescue
(Previously known as "
SystemRescueCD
")
[4]
is a
Linux distribution
for
x86-64
and
IA-32
computers.
[5]
The primary purpose of SystemRescue is to repair unbootable or otherwise damaged computer systems after a
system crash
. SystemRescue is not intended to be used as a permanent
operating system
. It runs from a
Live CD
, a
USB flash drive
or any type of hard drive. It was designed by a team led by Francois Dupoux, and is based on
Arch Linux
since version 6.0.
[6]
Starting with version 6.0, it has
systemd
as its
init system
.
[7]
Requirements
[
edit
]
For more recent versions, a 64-bit processor is required, with 32-bit processors being deprecated after version 9.03 in 2017.
[8]
[9]
PowerPC
had a single release with version 0.2.0 in 2004,
[10]
with
SPARC
also having one for version 0.4.0 in 2007.
[11]
If a
PXE
boot requires
HTTP
or
TFTP
, at least 1GB of memory will be needed for loading a required file for those into memory. However if
NFS
or
NBD
is used, the 1GB requirement isn't necessary.
[12]
Running the live cd from memory is recommended for speed and not requiring the boot device to be connected after boot, however it does require installed memory to be at least 2GB.
[13]
[9]
Bootable USBs have become preferred over CDs or DVDs due to the more recent size increases of the distribution and due to the lack of optical drives in many modern devices.

, hardware diagnostics and the ability to create other boot disks from a single CD
[16]
Burning CDs/DVDs and creating a bootable USB
[
edit
]
The live cd iso file being installed needs to match the system being used; for 64-bit x86-64 processors
amd64
is used, for 32-bit IA-32 processors
i686
is used.
[9]
The supported architecture is listed at the end of the iso filename.
The CD can also boot from a customized DVD which has almost 4.6 GB of free space for backed-up files. This makes it good for storing all the information that is needed from a hard drive and then formatting it. To burn the DVD, one must burn the image file first and then add all the separate files and folders.
[9]
This should not affect the general way in which the DVD works. The DVD can then be used to insert those files into the hard drive using Midnight Commander.
The system-rescue iso can be used to create a bootable USB device using tools such as
rufus
,
ventoy
, or the
dedicated linux tool
. The USB must have at least 2GB of storage and be formatted in FAT32.
