System rescue is a very important word in the computer world. It means to recover from a crashed system and safely carry out all the important data from a crashed computer. It does not matter which type of OS you are using; you just need to know how to rescue the system. I am an expert in software and I can rescue any crashed system; I can recover data and the operating system too in most of cases. To start a rescue operation, you must have a live CD that will help you to access the unbootable system. Rescue operation of a system becomes easy if the system is booting fine and we solve most of our problems on a running OS but it might be difficult if the system is not booting. With a non-booting system, our primary aim is to recover all the data first before trying out any solution since a wrong solution can wipe out all the available data from the hard drive.
To get data back from any crashed and unbootable system, we need a live CD to access all the available partitions on the system. Microsoft does not give us this type of solution – we can use its own recovery feature to start Windows back but many times we are not able to boot the system. At this point, the only way we can recover data is by using any live CD which makes the system bootable using its own booting operating system. SystemRescueCd is one of the most popular rescue live based on Linux OS. You can say it is the Linux system rescue disk to use on a Linux system but you can use it on Windows too to recover all of your important data. Personally, I have used this CD on numerous occasions and in most cases, I successfully recovered my files like my Mp3 collections, software and documents files.
We can use SystemRescueCd as live or we can make a bootable USB pen drive if a CD drive is not available with the system. Once you boot the system using this CD, you can edit or create a new partition on the drive and move all your data there. You can use this rescue CD on both Linux and Windows to backup data. To backup data, we can attach any USB pen drive to the system and then move all the files to the USB or any external storage drive. This rescue system requires no installation as it can be booted from a CD/DVD drive or a USB stick, but it can be installed on the hard disk if you wish. Rescue CD kernel supports my available file system for both Linux and Windows like ext2/ext3/ext4, reiserfs, btrfs, xfs, jfs, vfat, ntfs and network file system (samba and nfs) as well. So you have a full chance to recover data from any crashed or unbootable system.
You can install the complete SystemRescueCd on a USB pen drive using USB installer which is available on its website manual page. To create a bootable USB from SystemRescueCd ISO image, download USB installer from its manual page and start. You will also need a CDRom ISO image file [download link at the end of post] because USB installer is the only utility that does not come with any bootable image. USB installer is very easy to use. Just browse CDRom ISO image files and removable device then click on the Install button. You can also set some settings on the USB installer such as keyboard mapping, kernel image, network configuration mode and other display related settings.
Once you successfully create a bootable USB drive, insert it in the system to start rescue and select first boot device as USB. After booting from USB, you will see the main screen of this recuse cd and you can choose between all the available options from there.
