Boot from an external HARD drive via USB

I have an 8200 Elite SFF and wants to start an alternative system (not Linux, but * NIX - like BONE) of a disk external DRIVE, connected via a USB port. My main operating system is WIN 7 64 bit, but for some special tasks I´d like to use the alternative OS. It worked without any problem on my two previous stand-alone - elected USB as a boot device in the BIOS boot menu and it starts fine.  However, on my Compaq 8200 there no USB option in the start menu. However, when I connect the external HARD drive to a USB port, the name of the HARD disk appears in the start menu, but again, it won't start him.  Have heard that there is a tweak to fix this, or maybe I m wrong. Alternatively, my stand-alone motherboard just can´t boot from an external hard drive via USB? Any ideas?



Unplug everything plugged to the computer except the keyboard, mouse and monitor.

Then use this method to Flash the BIOS.  It's the best way to go.

USB Device Flash BIOS DOS

BACK Flash (DOSFlash.exe, FlshUefi.cpu) is the Flash BIOS DOS compatible system utility that can be used from a bootable BACK storage device (where the 'BACK' refers to a number of operating systems such as FreeDOS, DR - DOS or MS-DOS). FlshUefi.cpu is the driver required for DOSFlash.exe. To Flash the BIOS of the system to a bootable USB storage device, you'll need to copy the contents of the BACK Flash file on the USB device, start the PC from the USB device and run the DOSFlash application. To see a more complete description of the BACK flash utility, view DOSFlash.txt located in the folder BACK Flash. This folder also contains the required binary BIOS image.  The binary image file is named xxx_MMmm.bin , where "xxx" is the family of BIOS, 'MM' is the major version number and "mm" is the minor version number.  This file can be copied to the root directory of any removable media USB for use with F10 setup option «Flash system ROM»

The display of the folder BACK Flash content

The links on this post do not work. I copied the section from the BIOS flashing instructions for the specific section you need.

  • Of failure, white screen MacBook Pro HARD drive try to boot from the external HARD drive


    I have a 2008 Macbook Pro which is having some problems, I was able to fix them, but eventually the hard drive failed. I know that because at startup until it would have a white screen Uni (no logo) and you can hear a clicking on in the lower left corner. I thought initially it was a memory problem, but after opening and verification of memory, it's clearly the hard drive.

    I solved this problem temporarily (until I can replace the HARD disk) by installing El captain on an external HARD disc and start from that. Here's the twist, I couldn't he can begin to El captain, I tried CMD + R, CMD + OPT + R, CMD + OPT + R + P and now shift. Everything that's happened would be that clicks would cease to release the keys.

    I left the macbook on while I'm at work, when I got home it was on the screen to connect the external HARD drive.

    I accidentally closed the macbook yesterday and again once when I tried to log on, I could not and I left it on a white screen while I was sleeping. There is a possibility that he may have launched from the HARD drive when I get home, but if not, is there something that escapes me to force do this?

    Usually start up to a blank screen without the Apple Logo, may report one of the following:

    • Hardware failure
    • Boot drive is not recognized as valid and updated updated
    • OS X essential software is missing, hurt moved or renamed or corrupt
    • A firmware update is necessary

    No matter who, in order to boot from an external drive "bootable", you would normally hold down the Option key until you get a screen that offers a number of devices to try to boot from.

    Alternatively, you can try holding down the C key to try to boot from the external drive.

    If none of these startup options work, then the bootable disc or the USB port on your MacBook Pro can be the question.

    Since you have a Mac pre-2013, if you hold down the D key while booting, the built-in Apple Hardware Test should start up.  This can help to identify hardware problems.

  • Vista boot from the external HARD drive when 7 is installed on the internal HARD disk

    I had windows Vista pre-installed on my HP laptop, now I installed the new hard drive and downloaded windows 7 on it. and I use my drive HARD back as my external storage medium and it came with vista pre-installed. is it possible to start fromUSB and use vista alternately without remove current HDD with 7 and keep their replacement on a vice versa. I already changed the boot order, but it shows the blue screen and then goes out... help me if you think you have the solution for me...


    You can not install Windows vista on a USB hard drive. The reason is that manager (Bootmgr) boot will always be on the internal hard drive and will not read the USB drive letter properly and it continues to change.
    However, you can install the two HDD internally, and then you can have a dual boot option by adding the entries in startup of the operating system Windows Vista, Startup Manager (boot mgr).

  • Can I have macbook start up from my external hard drive instead of the internal HD of the laptop?

    I use a macbook air 2014 model and would like to know if I can boot the mac from an external hard drive rather than the inside. The reason to do this is to save space on the laptop and updates can be installed directly on the external hard drive.

    Is this possible? Forgive me, because I'm not that tech savvy. Thank you in advance!

    Yes. Install or clone of Mac OS X on it and then select it in the pane of the system preferences Startup disk.

  • I just downloaded winows meïdia player 11 it won't import my music from my external hard drive

    Winows meïdia player 11 won't import my music from my external hard drive whenever I try to add files, it just seems threw? How can I get my music in my library?

    The instructions are for WMP 11 on XP. Here are the correct steps to WMP 11 Vista: (note the reset of the library will make you lose all the counts to play and possibly ratings too)

    -Restart the PC.
    -Click Start, type services.msc in the search field and press ENTER. In Services, locate the Windows Media Player Network Sharing Service . If its status is started , double-click the service, and then click stop .
    -Click Start, type %LOCALAPPDATA%\Microsoft in the search field and press ENTER. This folder opens in Windows Explorer.
    -In this folder, rename the folder Media Player as Old Media Player . If you do not see the folder, then it is probably hidden. Set Explorer to view the hidden files and folders and show protected system files.
    -Launch WMP, your library will have been reset and will be rebuilt. Check if the problem persists.
