What is it for
ALT Linux Rescue is a moderate sized[1] LiveCD distribution that is designed to help sysadmins fix and repair many kinds of problems with systems they are or feel responsible for; so it comes with tools aiding to:
- perform hardware diagnostics
- resize partitions
- fix bootloaders, partitions, filesystems
- recover partitions and files deleted by accident
- backup and restore to network servers
- deal with optical, tape and file archives
- optimize filesystem usage
- diagnose network problems and remote services
- wipe partitions or drives clean of residual information[2]
- access Android devices, reset Windows passwords, etc
- investigate unauthorized access/security breach events
All of that is packaged into a convenient hybrid ISO image file suitable for both CD/DVD media and USB Flash pendrives[3].
The resulting media should be bootable on most x86 systems:
- 32-bit ones starting roughly with Intel Pentium II/160M or equivalent,
- 64-bit ones on any AMD64 compatible hardware with BIOS or UEFI[4].
But above all, don't panic, we've been there too!

 A Regular Build
|
These images are automatically built weekly[5], here are the direct download links to files which have been verified to boot already:
This is free software, you can use it, share it and enchance it too! And here are some alternatives.
Note the tips on suitable utilities to write the hybrid ISO image to bootable media; please do not use UNetbootin, Rufus, or UltraISO as those will cripple the result unfortunately.
Software spotlights
This is a GNU/*/Linux based LiveCD so all the software runs under Linux kernel[6]. Contents can be extended in runtime, just dhcpcd; apt-get update and install away.
Here are some of the packages included to get you started:
- refind to cope with the lack of EFI boot manager menu
- smartmontools for HDD/SSD S.M.A.R.T. monitoring
- testdisk/photorec to recover partitions and data files
- memtest86 for UEFI[7] and memtest86+ for BIOS
- android-tools, bonnie++, chntpw, cpuburn, dc3dd/dcfldd/ddrescue, exfat-utils, gpart, hdparm, ipmitool, lft, netcat, parted, rsync, scalpel, sleuthkit (aff/ewf), uudeview, whdd, wipefreespace...
There's more than a hundred of specialized programs there and many more are available through ALT Linux Sisyphus repository which serves as the base for this rescue image providing it with recent software versions. You can also rebuild it with the tools you need[8].
Forensic mode boot aims to minimize impact on media by avoiding activation of swap partitions, software RAID and LVM, mounting no filesystems and switching mount-system to readonly mode using loopback devices; press F2 and choose the appropriate option if UEFI booting. This mode enables hardening against rescue root filesystem spoofing.
"Rescue with remote SSH access (DHCP)" might come handy with laggy iKVM as it would bring up networking via DHCP, generate a root password, start SSH server and print the access parameters to the terminal so that only a few IP-KVM keystrokes are required to obtain faster shell. Please do change the password upon login.
