    hi everyone i am facing the below issue and want immediate solution.
    my laptop details:

    dell studio 1435

    when i am formating my laptop with windows7 usb drive it completed 85% and after that i am geeting the below error:
    windows boot manager

    windows failed to start. A recent hardware or software change might be the cause. to fix problem:
    1. insert your windows installation disc and restart your computer.
    2. choose your language settings, and then click "next."
    3.click "repair your computer."

    if you do not have this disc, contact your system administrator or computer manufacturer for assistance.

    status: 0xc000000f

    info:A required device is not connected or can not be accessed.

    Enter: Os selection

    when i click on enter it go to another window where it shows us to press F8 but when i m pressing f8 it goes to same error window.

    1) when i restarted it start with dell logo i press F2,F12,F10 all three i have press to open bios setting but nothing works it will go to same window so now i a not able to get into windows bios setup

    2) i tried to format it again as my dvd writer does not work so i tried with usb when i restarted my laptop it does not load the files and agin redirect to the same error window.

    so i have tried all these things to solve the problem but nothing works:(

    Seems like if the disc is not working all the way, it may be an error on your cd/dvd disc. However, you could have an issue with the drive. To find out if the drive is an issue, go into the bios and make sure you can see your HDD. If you can, then the problem is likely with the disc/ cd rom. Try using an external cd/dvd rom to install / format your device.

    I hope this helps.

    Hello & Welcome to TechGuy.org

    Which version of W7? 32 or 64 bit? Which service pack?

    How did you create the W7 usb drive? Please provide a web page, if that is easier for you.
    1 of these methods, for example? http://arstechnica.com/business/2009/12/the-usb-flash-drive/

    Did you use, as a source, a W7 DVD or a download?

    Excellent job of providing the screen information.

    Thanks for including your brand, model & model #.
    Here's the service manual.

    Here's the setup guide.
    http://downloads.dell.com/Manuals/a...435_Setup Guide_en-us.pdf?c=us&l=en&cs=&s=gen

    Why did you decide to reform your HDD & re-install W7? What kind of problems were you experiencing? Did you have a virus or other malware? There is a type of virus called a rootkit that will withstand a format. There are rare instances of BIOS infections, too.

    Per page 40 of http://support.dell.com/support/edocs/systems/1435/en/sg/sg_en.pdf
    Pressing F12 when the Dell logo appears should take you to the system setup [ BIOS ] as well as a diag menu.
    Please run all diags available and report the results.

    When did you upgrade from Vista to W7? How did you do that?

    Create a W7 repair disk. OR boot to the repair menu from your flash drive, it that option is available.
    Try to repair Windows 7. Is a W7 installation discovered?

    If not, please see http://www.bleepingcomputer.com/forums/t/469716/windows-7-ultimate/
