1.  Introduction

A rescue disk (a.k.a., rescue disc, repair disk/disc or recovery disk/disc) is bootable media that provides functionalities and utilities for fixing computer problems that prevent the computer from starting normally. Different rescue disks provide different functionalities and utilities. This Web page compares rescue disk functionalities and utilities.

Being bootable and portable, CD/DVD discs and USB flash memory drives are ideally suited for use as rescue disks. To use a rescue disk: 1.) create the rescue disk on a CD/DVD disc or USB flash memory drive; 2.) boot the computer from the rescue disk, not the computer hard drive; and 3.) run the rescue disk utilities against the computer hard drive.

i
USB external hard drives are also bootable and portable. However, rescue disks can be created typically only on USB flash memory drives, not on USB external hard drives.

To boot a computer from a rescue disk, insert the rescue CD/DVD into the CD/DVD drive or plug the rescue USB flash memory drive into a USB port, power on/restart the computer, and, if prompted, respond as necessary to boot the computer from the rescue disk. If the computer cannot boot from the rescue disk, and if the rescue disk was created successfully and is functional, and if the CD/DVD drive or USB port is functional, then either: 1.) the computer BIOS does not support booting from CD/DVD drives or USB drives, which is unlikely for computers manufactured since 2002; or 2.) the computer BIOS is not configured to boot from CD/DVD drives or USB drives, which means, to use the rescue disk, you must enter the BIOS setup program and configure the BIOS to boot from CD/DVD drives or USB drives.

i
Further discussion of the BIOS is beyond the scope of this page. For information on how to enter the BIOS setup program and how to configure the BIOS to boot from CD/DVD drives and/or USB drives, see the computer motherboard/BIOS documentation.

(1)  Norton Bootable Recovery Tool: Qualifying PIN/product key required to boot from the Norton Bootable Recovery Tool, not to create the Norton Bootable Recovery Tool. Qualifying product keys include Norton Antivirus, Norton Internet Security, and Norton 360. Apparently expired qualifying product keys are accepted. For example, a product key from Norton Internet Security 2008 that expired in 2009 was accepted in May 2013.
(2)  Norton Bootable Recovery Tool: Internet connection required to create the Norton Bootable Recovery Tool. When downloading virus definitions, since the Norton Bootable Recovery Tool download does not include virus definition, the entire virus definition database (~100-150MB) is downloaded, which can be prohibitive with slower Internet connections. Therefore, it is suggested that dial-up users use a malware free computer with a faster Internet connection to create the Norton Bootable Recovery Tool.
(3)  F-Secure Rescue CD: When downloading virus definitions, instead of downloading only updated virus definitions, the entire virus definition database, fsdbupdate9-packed.run (download.f-secure.com), (~130-150MB) is downloaded, which can be prohibitive with slower Internet connections. However, the F-Secure Rescue CD automatically looks for and uses fsdbupdate9-packed.run located on the root of an attached USB flash memory drive. Therefore, it is suggested that dial-up users use a malware free computer with a faster Internet connection to download fsdbupdate9-packed.run. If Internet Explorer opens fsdbupdate9-packed.run instead of prompting to save it, download fsdbupdate9-packed.run with Mozilla Firefox. To use fsdbupdate9-packed.run on a USB flash memory drive, if necessary, format the USB flash memory drive FAT or FAT32, not NTFS or exFAT | download fsdbupdate9-packed.run | copy fsdbupdate9-packed.run to the root of the USB flash memory drive | attach the USB flash memory drive and boot the computer from the F-Secure Rescue CD.
(4)  Norton Bootable Recovery Tool: Automatically downloads updated virus definitions at scan time, not manually. Therefore, to download updated virus definitions, click Start Scan.
(5)  F-Secure Rescue CD: To open command line, press Alt+F2. To close command line, press Alt+F1.
(6)  Avira AntiVir Rescue System: To open Midnight Commander, click Miscellaneous | Command line | press Alt+F5. To close Midnight Commander, press Alt+F7.
(7)  AVG Rescue Disk: Insert CD/DVD discs before booting from the AVG Rescue Disk, or boot from the AVG Rescue Disk, insert CD/DVD discs, and select Re-mount Windows volumes.
(8)  Avira AntiVir Rescue System: Insert CD/DVD discs before booting from the Avira AntiVir Rescue System, or boot from the Avira AntiVir Rescue System, insert CD/DVD discs, and click Miscellaneous | Include all devices.
(9)  F-Secure Rescue CD: To access CD/DVD discs from the command line, insert CD/DVD discs | open command line (see (5) above) | issue mount command. Cannot scan CD/DVD discs.
(10)  AVG Rescue Disk: To eject the AVG Rescue CD, select Eject rescue cd. To access a different disc inserted in the same CD/DVD drive, insert CD/DVD disc and select Re-mount Windows volumes.
(11)  AVG Rescue Disk: Attach USB flash memory/external hard drives before booting from the AVG Rescue Disk, or boot from the AVG Rescue Disk, attach USB flash memory/external hard drives, and select Re-mount Windows volumes.
(12)  Avira AntiVir Rescue System: Attach USB flash memory/external hard drives before booting from the Avira AntiVir Rescue System, or boot from the Avira AntiVir Rescue System, attach USB flash memory/external hard drives, and click Miscellaneous | Include all devices.
(13)  F-Secure Rescue CD: To access USB flash memory/external hard drives from the command line, attach USB flash memory/external hard drives | open command line (see (5) above) | issue mount command. To scan USB flash memory/external hard drives, easiest way is to attach USB flash memory/external hard drives before booting from the F-Secure Rescue CD.
(14)  Avira AntiVir Rescue System: To open AviraBrowser, click Online shop. Apparently it is impossible to edit the URL in the address bar.
(15)  Norton Bootable Recovery Tool: To open Registry Editor, click Launch Command Prompt | type regedit.exe | press Enter.
