    Windows Boot Configuration Data File does not contain a valid OS entry

    Hello, I apologize if this is in the wrong forum, and if there have been threads about this issue before, but I've searched for a while and could not find a solution that I could understand from reading, as I am a newbie. Whenever I start up my computer, it shows this:
    Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:
    1.) Insert your windows installation disc and restart your computer.
    2.) Choose your languange 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.
    File: \Boot\BCD
    Status: 0xc0000098
    Info: The Windows Boot Configuration Data file does not contain a valid OS entry.
    The computer runs windows 7 and is an Acer Iconia Tab W500, so it's a hybrid tablet and laptop and did not come with an installation disc, nor does it have a disc drive due to its size. I can't access the window that pops up with F8, the only screen that can appear is the F2 screen.
    I'm fine with completely restoring the computer to factory settings, or pretty much anything that will get the device working again. The problem is, I can't figure out how to either repair the file or restore. I'm really sorry if this is really confusing or if I didn't provide enough information, I don't have any experience with computers, but any advice on how to fix it?

    Do you have a Windows 7 Repair Disk?
    Do you have, or can you borrow, a Windows 7 installation DVD (Same version as yours)?

    If you follow the instructions in that message using either disk the chances are good that you can repair the problem.

    If you can't get your hands on a DVD, then when turn your computer on - tap on the F8 Key as soon as it comes on. When the black screen with options appear, select "Repair your computer." When you see the option, perform a Startup Repair.

    If startup repair fails then select the last option which allows you to access a command prompt. You might want to enter these commands at the prompt:

    • bootrec.exe /fixboot
    • bootrec.exe /fixmbr
    • bootrec.exe /rebuildbcd

    Is it possible to download the information of the disk online, and move the information onto a usb drive using a different computer, and then use it for this one? The device didn't come with a repair disk.
    Also, when I hit F8, nothing shows up except for the screen I described, so I can't access startup repair and command prompt.
