On any fireman: useful Live CD / USB for emergency start of the computer

    Hi, Giktayms ! Extreme measures to that and extreme, to address them from despair. Therefore, even in the case when the computer "went to the roof," there is an option to repair it without completely reinstalling the system. Today we will talk about bootable flash drives and look at simple obvious kits for working with PCs on the fly.



    More than alive


    The phrase Live% some kind of drive% came into use by PC users with the spread of Compact Disc. Prior to this, popular operating systems most often turned out to be thicker than the amount of RAM in computers, and the bootable floppy bootable flooded the most ascetic GNU / Linux distributions, often with a single program for working with HDD or repairing DOS. That is, the ball rules narrow specialization of “emergency aid” for specialists.

    But the Live CD, that is, “live CDs” (not as live as beer, but alive on a computer that has collapsed on the ground) could offer almost full-fledged operating systems and software wagons from above. After the "blanks" were retired, the transfer of the banner of bootable media picked up USB-drives. And in 2016, you can live on the desired gigabytes of the drive and the more or less relevant hardware from Live USB instead of a full-fledged installed OS or in luxurious conditions to repair the “fallen” Windows / Linux.

    Hardware requirements


    If you do not go to extremes, a banal Pentium 4 with 512 MB of RAM will be enough to run most of the boot kits. The most demanding builds require 1 GB of RAM and support for the PAE / NX / SSE2 processor.

    Requirements for drives are formed differently - you can even boot from ancient flash drives, but the speed of loading and system response time at the initial stage of operation will depend on their speed. Therefore, it is desirable to purchase something with a capacity of 8 GB (for multiboot versions or versions with integrated drivers) and with a solid reading speed. Yes, and a convenient for transportation case does not hurt, so as not to rush home / to the office behind the drive, when thunder clap.


    The launch of the boot CD is ready!

    In a word, Kingston DataTraveler SE9 G2or DataTraveler Micro 3.1 will fit perfectly, especially since there is no need for monstrous capacity, which means that you can prefer the fastest drives - the issue price will remain modest anyway.

    Face of morality


    If the licensed purity of the Linux distributions that are crafted in a different way on the Live CD is understandable, then the legal status of “live” Windows boot is in doubt. Because the specialized toolkit Windows PE (Windows Preinstallation Environment) is designed for OEM-assemblers, which also can not only be everything. Few people can be.



    Some Windows users sincerely believe that the use of WinPE distributions is a special case of the boxed version of the system as part of the EULA, but the wording of the license agreement is vague and can be interpreted more widely than some of the prophecies from the scriptures. In general, we advise readers to make sure at least that they use software in the boot distribution, the license for which has already been purchased earlier. ;-)

    Varieties of Live USB


    It’s relatively easy to create a boot distribution today (it’s difficult to create a good Live CD / USB), so the selection of live sets is huge, but from the bell tower of an ordinary computer user they can be divided into several categories:

    Boot disks to familiarize yourself with the system. The wording smacks of pirate mantras "we hacked it all up so that you, dear tracker users, will become familiar with the functionality of the software to the fullest and infinitely long." But in reality, Live USB allows you to touch the system, which put on the "combat" computer hand does not rise. For example, take a lookon the most friendly linux for neophytes if still not. And just to assess what Open Source has come from using the example of free distros, and not stitched from free and not very Android binaries.

    By the way, about Android - now on the PC you can run Android 6.0 in every possible way , and a little later it will come to the “ seven ”, which is nougat.



    Finally, you can see how people overcome difficulties and create Windows, which is not Windows . To this day, this utopian undertaking causes skepticism among geeks, but the developers' zeal is reminiscent of the story of recreating dinosaurs from the DNA from the Jurassic Park film. Romance, in one word.

    The vast majority of "operating systems" are converted to work in the Live CD mode. Is that OS X (Mac OS) for obvious reasons stands alone.

    Antivirus Live USB. On the one hand, a special case of “repair” distributions, but since the time of the violence of the winlockers, stand-alone scanners for malware have become a separate caste of boot systems.
    After the majority of antiviruses missed the appearance of ransomware Trojans, in order to justify and for the future, developers of computer security software began to release Live USB on a regular basis. Today , Kaspersky , Dr.Web , ESET , Avira , Avast , AVG ... and others, as they say in Hollywood action movies, offer anti-virus boot versions with fresh (as much as possible in regular disk builds) signatures .


    The average antivirus boot disk

    There are in this caste bootable distributions and less untwisted means - for example, a specialized utility AntiWinLockerLiveCDor a combine called Stop SMS, which is stuffed with paid utilities.

    Tools to restore the system or prepare for installation. These include Microsoft DaRT (Diagnostics and Recovery Toolset) and ERD Commander on its base. Such a kit is able to resurrect Windows from a half-dead state. Tiny Memtest86 to test the performance of RAM, MHDD to diagnose and save the hard drive (or better buy a good SSD ) and all sorts of bootable stress tests.


    MS DaRT Tools

    All-in-one sets for working without using the main drive.In the case of such distributions we are talking not so much about resuscitation or preparing a computer for a new operating system, but about the possibility of “sitting out” behind a PC in case the hard disk / SSD orders you to live a long time. Therefore, distributions include TCP / IP support, PPPoE and Wi-Fi, hardware drivers are installed right before the desktop is loaded, and the distribution includes browsers, audio and video players, text editors, archivers, file managers, printer support and other goodies. For the reasons described above, so hard-modified “OSes” are not at odds with the law, so today we will limit ourselves to mentioning one of the most shocking Live CDs of this type - Lex Live Startlex 2014. A grand and workable assembly even on “old ruins”.

    How to burn a boot disk to a flash drive?


    There is no single recipe. Shaken up Windows versions make it possible to activate the boot record using the Bootice utility and GRUB4DOS, antivirus distributions are most often equipped with one-button installers, in which you only need to point to the drive, GNU / Linux unsuited options are conveniently spread across the drive by the multi- YUMI manager . All that does not want to be installed in an amicable way, it is customary to deploy on flash drives with the help of the ruthless UltraISO program .

    Jedi are free to come to similar functionality in a different way , but let's be merciful to beginners and not begin to stuff them with handyd and dominate the code after the portions of the already complex in the perception of information?


    UltraISO is a famous utility for creating bootable disks.

    It’s impossible not to mention the popular now Rufus - it is suitable for writing USB for any type of BIOS, quickly (much faster than WIndows 7 USB Download Tool) will write the image to a USB flash drive, and I haven’t never failed your humble the servant.



    Creating your own Live CD / USB


    Development of a custom version of the bootable flash drive consists of the work of scripts and the search for programs suitable for portable-work. Respected habrayusers wrote in detail about the implementation of various applications in one drive , and the preparation of modern versions of Windows for creating a boot disk was discussed in an older, but still relevant article on the 3DNews website . We recommend novice users not to plunge into hardcore with a head (there is a risk to get carried away and forget, for the sake of which they embarked on this venture), but nothing will stop the perfectionist, right?

    Is it faster to reinstall?


    The steeper the “jeep” - the farther it is to run in search of a tractor to rescue the car from the dirt. The more massive Live USB is, the more anti-virus software and anti-virus signatures become obsolete with it. Always evaluate what “techniques” you will need in the emergency operation of a computer and choose only those distributions that will be really useful and fast on your computer. Stable work for you and hassle-free software!
