Rescue and recovery disks are used for repairing a system and data after a crash on Linux and Windows devices.
They are especially useful for troubleshooting of the boot-related issues and for data recovery.
In this note i will show how to create a bootable rescue USB stick with a SystemRescue (also known as a SystemRescueCD) – a Linux-based rescue toolkit for administrating and repairing of the Windows and Linux-based systems and data recovery.
Linux Recovery USB Creation
Download the latest version of the SystemRescue image from the official download page.
Created Recovery USB Drive on Windows
Download and install a Rufus (Reliable USB Formatting Utility with Source) on Windows or just download and run a portable version that doesn’t require installation.
Select a USB drive, select the SystemRescue image that you should have already downloaded, tick the “Quick format” box to speedup the bootable USB creation process and click on “START”:
During preparation you may be asked for a couple of questions – in the most cases it is preferable to keep the recommended options.
When the status changes to READY – close the Rufus and eject the USB stick.
Created Recovery USB Drive on Linux
Plug in your USB stick and run the
lsblk command to identify the USB device name:
$ lsblk -fp NAME FSTYPE LABEL UUID MOUNTPOINT /dev/sda └─/dev/sda1 LVM2_member c52... ├─/dev/mapper/mint--vg-root ext4 183... / └─/dev/mapper/mint--vg-swap_1 swap 337... [SWAP] /dev/sdb └─/dev/sdb1 vfat USB Drive 345... /media/user/usb0
Unmount the USB stick, for example:
$ umount /dev/sdb1
Copy the SystemRescue image to the USB stick (this may take up to 5 minutes):
$ sudo dd if=<systemrescue_iso> of=<usb_device_name> status=progress - example - $ sudo dd if=~/Downloads/systemrescue-8.06-amd64.iso of=/dev/sdb status=progress
Once the creation of the recovery USB drive is completed – eject the USB stick.
Boot from Linux Rescue USB
Insert the recovery USB stick with the Linux-based SystemRescue into a computer that needs to be repaired.
- Power on the computer and enter the BIOS settings
- Search for the “Boot Order” settings
- Move the recovery USB drive to the top of the “Boot Order” list
- Press the
F10to save and exit
Enter BIOS: Common keys to enter the BIOS are
If while trying to boot from the recovery USB drive you are getting something like:
Selected boot image did not authenticate
– or –
Invalid signature detected
… you may need to disable the “Secure Boot” in your BIOS settings.
After booting from the SystemRescue USB drive, by default you’ll be dropped into a standard Linux shell prompt.
If you need to start a GUI (Graphical User Interface), run:
