==Structure Requirements ==
For more recent versions, a 64-bit processor is required, with 32-bit processors being deprecated after version 9.03 in 2017.<ref>{{Cite web |date=2022-05-30 |title=Support for the 32bit architecture (i686) (#278) · Issues · SystemRescue / systemrescue-sources · GitLab |url=https://gitlab.com/systemrescue/systemrescue-sources/-/issues/278 |access-date=2024-05-04 |website=GitLab |language=en}}</ref><ref name=":1">{{Cite book |url=https://fastly-cdn.system-rescue.org/download/books/SystemRescue-Getting-started-20220205.pdf |title=SYSTEM RESCUE A STEP BY STEP GUIDE TO GETTING STARTED |date=2022-02-05 |publisher=system-rescue |pages=7-8, 9, 11-12, 19-20}}</ref> [[PowerPC]] had a single release with version 0.2.0 in 2004,<ref>{{Cite web |date= |title=SystemRescueCd - Browse /sysresccd-ppc at SourceForge.net |url=http://sourceforge.net/projects/systemrescuecd/files/sysresccd-ppc/ |archive-url=https://web.archive.org/web/20130926044705/http://sourceforge.net/projects/systemrescuecd/files/sysresccd-ppc/ |archive-date=2013-09-26 |access-date=2024-05-04 }}</ref> with [[SPARC]] also having one for version 0.4.0 in 2007.<ref>{{Cite web |date= |title=SystemRescueCd - Browse /sysresccd-sparc at SourceForge.net |url=http://sourceforge.net/projects/systemrescuecd/files/sysresccd-sparc/ |archive-url=https://web.archive.org/web/20130925205537/http://sourceforge.net/projects/systemrescuecd/files/sysresccd-sparc/ |archive-date=2013-09-25 |access-date=2024-05-04 }}</ref>
SystemRescueCd is capable of graphics using the [[Linux framebuffer]] option for tools such as [[GParted]]. It uses version 3.14.48/3.18.18 of the Linux kernel and has options such as connecting to the Internet through an [[Asymmetric Digital Subscriber Line|ADSL]] [[modem]] or [[Ethernet]] and graphical [[web browser]]s such as [[Midori (web browser)|Midori]].
 
If a [[Preboot Execution Environment|PXE]] boot requires [[HTTP]] or [[Trivial File Transfer Protocol|TFTP]], at least 1GB of memory will be needed for loading a required file for those into memory. However if [[Network File System|NFS]] or [[Network block device|NBD]] is used, the 1GB requirement isn't necessary.<ref>{{Cite web |title=SystemRescue - PXE network booting |url=https://www.system-rescue.org/manual/PXE_network_booting/ |access-date=2024-05-04 |website=www.system-rescue.org}}</ref> 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.<ref name=":0" /><ref name=":1" /> 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.<ref name=":1" />
 
==Features==
SystemRescue is capable of graphics using the [[Linux framebuffer]] option for tools such as [[GParted]]. It has options such as connecting to the Internet through an [[Asymmetric Digital Subscriber Line|ADSL]] [[modem]] or [[Ethernet]] and graphical [[web browser]]s such as [[Mozilla Firefox]].
SystemRescueCd has several features, some of them include:
*[[GNU Parted]] and [[GParted]] to partition disks and re-size partitions, including [[File Allocation Table|FAT32]] and [[NTFS]]
*[[fdisk]] to edit the disk [[partition table]]
*[[PartImage]], [[Disk image|disk imaging]] software which copies only used sectors
*[[TestDisk]] to recover lost partition and [[PhotoRec]] to recover lost data
*[[FSArchiver]] a system tool that allows you to save the contents of a file-system to a compressed archive file
*A CD and DVD burner: [[dvd+rw-tools]]
*Two bootloaders: [[GNU GRUB|GRUB]] and [[SYSLINUX]]
*Web browsers: [[Firefox]], [[Midori (web browser)|Midori]], [[ELinks]]
*File manager: [[emelFM2]]
*Archiving and unarchiving abilities
*File system tools: file system create, delete, resize, move
*Support for many file systems, including full NTFS read/write access (via [[NTFS-3G]]) as well as FAT32 and [[Mac OS]] [[Hierarchical File System|HFS]]
*Support for Intel [[x86 architecture|x86]] and [[PowerPC]] systems, including [[Macintosh (computer)|Macs]]
*Ability to create [[boot disk]] for operating systems
*Support for [[Microsoft Windows|Windows]] [[Windows Registry|registry]] editing and password changing from Linux
*Can boot [[FreeDOS]], [[Memtest86+]], hardware diagnostics and other boot disks from a single CD
 
The [[File system|File systems]] supported by System-Rescue are [[btrfs]], [[ext3]], [[ext4]], [[FAT16]], [[FAT32]], [[ISO 9660|ISO9660]], [[JFS (file system)|JFS]], [[NTFS]], [[ReiserFS]], [[VFAT]], and [[XFS]]<ref name=":2">{{Cite web |title=SystemRescue - System Rescue Homepage |url=https://www.system-rescue.org/ |access-date=2024-05-03 |website=www.system-rescue.org}}</ref><ref name=":3">{{Cite web |title=SystemRescue - SystemRescue Overview |url=https://www.system-rescue.org/manual/Overview/ |access-date=2024-05-03 |website=www.system-rescue.org}}</ref>
==Burning DVDs and system backup==
 
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 has to burn the image file first and then add all the separate files as well as folders. This should not affect the general way in which the DVD works. Then the DVD can be used to insert those files into the hard drive using [[Midnight Commander]].
There are two bootloaders supporting the OS – [[GNU GRUB|GRUB]] & [[SYSLINUX]].<ref name=":0">{{Cite web |title=SystemRescue - Booting SystemRescue |url=https://www.system-rescue.org/manual/Booting_SystemRescue/ |access-date=2024-05-04 |website=www.system-rescue.org}}</ref>

Additionally, the live cd also allows for booting to [[FreeDOS]], [[Memtest86+]], hardware diagnostics and the ability to create other boot disks from a single CD<ref name=":4" />
 
==Burning CDs/DVDs and creating a bootable USB==
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.<ref name=":1" /> 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.<ref name=":1" /> 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 (software)|rufus]], [[ventoy]], or the [https://gitlab.com/systemrescue/systemrescue-usbwriter dedicated linux tool]. The USB must have at least 2GB of storage and be formatted in FAT32.<ref>{{Cite web |title=SystemRescue - Installing SystemRescue on a USB memory stick |url=https://www.system-rescue.org/Installing-SystemRescue-on-a-USB-memory-stick/#:~:text=You%20should%20use%20a%202GB,a%20key%20at%20boot%20time. |access-date=2024-05-04 |website=www.system-rescue.org}}</ref>
