Is the virtual USB key secure?

Comments from the media about such as Stuxnet malware often contain advice "always test the USB key in a virtual machine to a sandbox using sand Linux xyz". My question is, IS this really a safe way to deal with a USB key, since a virtual driver must be loaded first?

Is this procedure reasonable first line of defense, or is it a dangerous myth?

If I need to test everything that perhaps is infected I have never attach to a system running normal or him allow direct access to the local network.

In the case of a USB key I'll tie it to a system on the bench which is not a hard disk, is not connected to the LAN and has started from the CD/DVD/USB containing appropriate and undated utilities to digitize and effectively deal with all threats.  If I booted from a USB Flash drive, then when you're done, I'll reboot from CD and then drop an Image of own ghost well-known on the USB thumb drive to ensure that it is clean and ready for the next use.  I know that may sound like an exaggeration, but it's a healthy and solid way to make sure that I have not to contaminate my local network or one of the systems on the bench belonging to other customers or when I go into the field and use of my USB devices to attach to or start client systems.

Now he safely do endearing to a Virtual Machine, no doubt, but I'm not willing to roll the dice so when using the methodology mentioned before is a way better and safer to deal with the unknown.  That said if I only had one system then I have always known of the own media Boot Live good vs HARD drive internal and before connecting the dubious device make sure the internal HARD disk is not mounted.

IMO it is absolutely no good reason whatsoever to take a chance or a risk infecting a well known clean system work when there are solutions of easy alternatives that are safer and IMO the right way to deal with the unknown, when it comes to issues like this.

If for any reason, the virtual computer does not enter and mount the front USB host don't then, as for example if the host is Windows and appropriate precautions are not in place and autorun starts it might be at the end and why I prefer to play more sure and never have to give it a second thought as to whether or not I've infected my LAN or contaminate any of my Clients of systems in the field with my own devices.

    I was not able to complete the full implementation of the solution Dell Direct USB key due to various problems.  .    Dell ended up sending me a new Windows 7 HARD disk image.   I have now the laptop up and running again with Windows 7 and have various applications installed.   That's all pretty well.  But now how do I get my data files restored?   Basically, I want to connect the external drive to backup and complete step 19 of the solution, as described below.

    
    Here are the steps OS using the Dell USB key: 
    
    1. Boot from the Direct USB Key by tapping F12 at the Dell logo, then select the
    USB Memory Key option from the boot device menu. 
    
    2. Accept the Dell End User License Agreement (EULA) by clicking the box next to
    Accept, scroll down till the end of the license agreement and then click on
    continue. 
    
    3. On this screen, the usb key gives an overview of the process it is about to
    perform, click continue when ready to proceed. 
    
    4. The Smart Repair solution runs a surface scan on the system to identify any
    errors with the boot record or the startup files. If any errors are found, they
    are automatically corrected. 
    
    5. Once the process completes, there will be an analysis summary, in this case,
    there is no issue found by the smart repair, click continue. 
    
    6. In this window the user can select what data they would like to back up, they
    can either go with the default backup solution or they can click select more to
    select more files for backup, click continue after selecting files for backup. 
    
    7. If user clicks on select more, they will get the screen below, they can go
    ahead and select the necessary data for backup by checking the box next to the
    respective folder, sub-directories are selected by default once the root folder
    is selected. 
    
    8. The user will be prompted to attach a USB hard drive to the system, user
    needs to connect the USB Hard drive at this point and click continue. 
    
    9. Once the solution detects the USB hard drive , it goes ahead with file
    backup. 
    
    10. Once the files are backed up, the solution will back up the user personal
    settings. 
    
    11. The Direct USB Key displays a summary of the data and personal settings
    backup. Click continue. 
    
    12. The Direct USB key then proceeds to install the operating system image on
    the system. 
    
    13. Once the operating system image is transferred, the drivers are also
    transferred. 
    
    14. After the operating system image and driver transfer, a summary page comes
    up giving the user information as to what process was performed successfully and
    what failed. The user needs to remove the USB key at this point and click
    restart. 
    
    15. The system restarts and comes to a flash screen on recovery and restore. 
    
    16. After the flash screen, the applications start installing. 
    
    17. Once the applications are installed, the user would see a summary screen
    informing them that the Operating system has been restored, connect the Direct
    USB Key and click restart. 
    
    18. After the restart the user will be prompted to connect the data backup hard
    drive and then click continue. 
    
    19. The files and personal settings are then restored from the USB backup drive. 
    
    20. After the files are transferred the system comes to the desktop with a pop
    up window informing the user to check the device manager for any exclamation
    marks, the tool also guides the user to download the drivers from the support
    site and the applications from My Dell Downloads and Dell Digital Delivery. User
    needs to select the check box to prevent the message from being displayed again
    and click close.

  • Lenovo B590 won't usb key boot

    I just bought this laptop and it came with windows preinstalled 8, and I'm trying to install Windows 7 on it.

    I have a bootable usb key, which I've used several times to install Windows on my other laptops, but the just B590 won't. I feel I have tried everything. I changed boot priority in the BIOS with USB HDD as number 1, but it always starts just in windows 8.

    I tried to delete everything except the boot order USB devices, and now I get this start menu:
    http://i.imgur.com/1iV2iaW.jpg

    Which is exactly what I want to boot from, but when I press ENTER to boot the USB device, nothing happens. It's incredibly frustrating.

    The USB device IS bootable with a primary partition. I used these steps to make it bootable in DISKPART:
    http://social.technet.Microsoft.com/wiki/contents/articles/234.how-to-deploy-Windows-7-from-a-USB-Dr...

    After having no luck on the B590, I tried to boot from the USB stick on another computer and it works perfectly fine. Start the installation of windows 7. This suggests that the problem is not with my USB.

    I even tried to restore the USB and use Lenovo generator Bootable application to make the bootable usb key, with the same result.

    Can anyone help?

    Secure Boot should be disabled

    In case the above options are grayed out in your BIOS, got to the tab out and change OS optimized defaults to other OS

    and look at the options.

    Once all are set be sure to save all changed by pressing F10 and enter for Yes

    After Hitting enter it restart and you have to keep tapping F12

    This should make the Start Menu that lets you choose where to start. You should now have your USB optional.

  • Tool for creating media, Windows Bootable USB key problem

    Hey, when using of media creation tool to download and make N 8.1 Windows Bootable on my 64 GB Kingston, USB 3.0, the process gets all the way to the end before failing and say "sorry, something happened and we could not finish creating the flash drive in the drive I got access denied." So my question is; Why won't it work?

    Use the multimedia creation tool to download and save the .iso image file. Do not use it to make the USB. This prevents you wasting time downloading Windows 8.1 and then having to redownload as the tool does the USB incorrectly. Rufus makes the Bootable USB key. Its best to use a 8-32 GB USB flash drive and FAT32 format (64 GB will be truncated to 32 GB for FAT32).

    If you install in the UEFI with SecureBoot (new Security Technologies - made systems in 2012 or later systems in 2010-2011 may also have the UEFI BIOS with the latest BIOS update but the settings must be enabled) use the "GPT partition for UEFI computer scheme." Be sure to format it in FAT32 or the USB Flash drive will not start.

    If you install in a legacy systems BIOS for systems without a UEFI BIOS, then use the "partition MBR BIOS laptop scheme." Its also recommended to format the Flash drive to FAT32 but not necessary for a Legacy BIOS.

    Hello

    1. you are trying to install Windows XP by using the bootable USB key?

    Check if the sequence of the BIOS (Basic Input Output System) is set to boot to the operating system from the USB key.

    For more information get in touch with the manufacturer of the system.

    Note:

    BIOS change / semiconductor (CMOS) to complementary metal oxide settings can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the configuration of the BIOS/CMOS settings can be solved. Changes to settings are at your own risk.

  • Cannot start T400 USB key.

    I'm trying to start a Lenovo T400 laptop computer from a USB key.  The USB key contains a version of Ghost that I start in order to image the laptop to my Ghost server.  I can successfully start a Ghost on a CD session, but I have to change the SATA settings in the BIOS to achieve this.  I'm trying to get away from the CD and change the BIOS.

    Hey, Zoltan-thanks for the post, it was very helpful.  I'm not fluent in Linux that I'd probably, but your mention of the HP trainer got me interested in it.  I reformatted the drive USB with the HP USB Disk Storage Format Tool and then copied back all my files.  I can now successfully start a Lenovo T400 with my USB.  I was using a Windows 98 bootdisk to fdisk and then format the drive.  (This is my first attempt at this and a colleague suggested it was the right way to go)  Even if the system with the USB drive as C drive, I guess he doesn't properly format it as the active drive.

  • How it warns all downloaded documents to visit the virtualized Documents folder

    Just got a new laptop with Windows 7 and I am very frustrated with the limitation of ridiculous security interfering with my work.

    I download a lot of files jpg of Ancestry.com.  They seem to go in My Documents folder that you specified, but are not visible in Explorer.  This happens with all files downloaded from the internet even if done on the desktop. After 3 unsuccessful attempts of Geek Squad agents, I finally understand they're going to temporary Internet files / virtualized. It seems that my C: drive all is now assigned as C: / appears under the virtualized folder.  I can get around this problem of security assinine to track down files and moving them to the location I thought I was keeping them but it is a real pain.  Is there a setting that I can change so that these files are not in the folder virtualized?  How can I get my C: / drive out of the virtualized folder?  Security doesn't let me do anything with it and I am the one and only user/administrator on this computer.  Windows XP, how I miss you?

    OK - as far as I know Windows 7 does NOT come natively with a folder "virtualized" whatever it is, you're talking about.

    If this is a NEW computer, then I think you should contact the support desk for your brand on what is happening.

    Thank you for posting. I read your post and I understand that when you create the recovery media, it stopped and gave you the message of the one copy can be made. I wanted to help with that.

    Due to licensing restrictions, you can create one HP a computer recovery solution. This message appears when the recovery media has already been created. If you bought a previously used computer or store but the computer was already open, then recovery media has probably been created before you bought the computer and this message is normal. If the computer is less than a few years, then you will probably be able to get a HP recovery solution. There might be a fee according to the status of the security of the computer, the country / region the computer was purchased, and the condition that generated the message.
