    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." "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.

    likely ram or hard disk failure... or bad dvd drive interrupting hdd operation.

    on dell laptops . diagnostic is started by
    hold Fn and power on
    see if tests pass.

    i had the same problem.

    i tested the hard disk with hiren's bootcd and it had some bad sectors.

    i replaced with an old hard disk i had laying around and no problems since.

    As I understand, you aren't getting inside the BIOS. To enter BIOS in any DELL laptop, press F2 without using the 'Fn' modifier key. It is note that Function keys in a laptop work as normal F keys (i.e., without modifier) before the OS loads. Enter the bios, change the boot drive order and reinstall windows. That's the best option. Of course, you can use the installation disc to repair the installation existing. Feel free to contact me. :)
