Bitdefender RescueCD requires username password



Bitdefender RescueCD versions 2011 to 2014 randomly require username and password to login to rescuecd.unknown_domain computer console, as described in this blog.



Unknown to the author. The same CD or USB thumb drive start automatically on other computer systems.



Type for username livecd and leave the password empty. After a successful login type startx to start the GUI.

      1. hey i have a problem after i type startx i get a fatal server error and i get some information and come back to give in the command startx

      2. Hi Florian, what does the error description say? You can google around based on the output. Usually this is caused by an exotic GPU that is missing the proper drivers.

      3. HI,
        I am running a gtx 970
        this is the log what rescue_cd spits out after i type in startx
        xauth: file/home/liveccd/.serverauth.5555 doesnot exist
        xauth: file/home/livecd/.Xauthority does not exist
        than it give me some information about a server and than
        fatal server error
        (ee) failed to create screen resources (ee)
        (ee) server termitated with error 1 closing log
        xinit giving up
        xinit unable to connect to server; connection refused
        xinit server error

  1. Tush! 970 had some problems with linux because of incorrect memory specs. If you have two monitors connected, disconnect the second. Also check that you are using the current version (May 2015). Anything else is beyond my knowledge: I am even not quite sure which distribution the guys from BD are currently using; earlier it was Knoppix. Simply ask them directly 🙂

  2. Thank you so much for the info. I needed to disinfect a server (with a very standard motherboard, plenty of RAM, no fancy GPU etc) and rand into this problem. The only info on the BitDefender site I found, was to ensure that it had at least 512mb RAM. Useless! Your info got me up and running. Many thanks

  3. That info helped me as well, Thank you. Do you know if this rescue disk can remove ransom ware? The kind that encrypts files? I know it won’t decrypt the files, but will it at least keep the virus from doing more damage?

    1. Hello Jay, I have no information about this so far. But I presume that it is possible – since the scan engine of the installed version did block such malware for me.

  4. Apparently, the staff at BitDefender is overwhelmed by the task of customer support. The thread on the BD rescue CD ran for 3.5 years on BitDefender’s own support forum before the thread was put out of its misery with the magic solution– login with “livecd”, use no password and enter “startx”. Most revealing, this solution was contributed by a user, not BitDefender staff– who insisted to the end nothing was wrong with the software, even if few customers could make it work.

    For every user, what may happen with the BitDefender rescue CD / boot flash– as many have pointed out– depends on a number of factors. In my own experience with a standard, but aging eMachines Athlon X2 with 4gb RAM and integrated video, the login, password and start command combination above eventually worked. Eventually, because after entering the combination, I got an “incorrect server address” advisory, and had concluded the game was over.

    But only minutes later, as I prepared to ask BitDefender tech support about the correct server address, and how to edit that address into place, I glanced at the screen– which for 10 minutes had displayed “Loading dababase, please wait.” (with no indication of progress in the load task)– and found BitDefender finally had loaded what it needed for a scan (this infected machine was not internet-connected), and was busily detecting malware, or so, I hope.

    This Transylvanian nightmare seems over, for now, But the BitDefender experience is a reminder that quality control, information flow and consistency is very much a cultural thing– even an afterthought. After two generations under dictatorship, we can only imagine the damage done to basic transparency at even the engineering level. Presumably, BitDefender has made sure the coders who did not document their work suffered a horrible fate, but that is only a guess. Perhaps they were elected “engineers of the month”, instead.

  5. Transylvanian Postscript–
    On its first scan, BitDefender rescue disk detected 31 instances of malware, but failed to remove all it had identified. After having been instructed to disinfect all 31, five could not be disinfected, so I instructed BD to delete the remaining five. Unfortunately, the English command for delete was rendered “ignore” (somehow), and BD finished its operation, proudly announcing it had ignored the remaining drive instances.

    On my presumption the fault was merely pilot error, I reran the scan for another 45 minutes, but found BD again refused to delete the five malware instances. BD posted no explanation for its refusal, but again announced it had spared the remaining five instances.

    This BD failure is serious enough to threaten, if not condemn any system, since only a single instance of malware can open the gates to a ransomware infection. For this reason, I have decided– as I did last year– against purchase and installation of BitDefender on any system. It is one thing for an application to be generally excellent in all the major categories, as BD has been judged by many reviewers, but quite another to be haphazard and illogical as a signature trait.

  6. Where is the option for posters to edit out their own typos, after posting? WordPress once offered a timed interval in which posters can edit their own work, but that interval is not a default– it must be chosen. Providing that interval for editing significantly elevates the quality of all posts, since users can self-edit and correct, avoiding the problems plaguing other blogs.
