How can I boot into Windows after uninstalling Ubuntu from my dual boot machine?

I have just used EasyBCD to try and restore the Windows boot loader before I attempted to uninstall Ubuntu Netbook Edition from my no CD drive EEE PC.

I was following the instructions by Jeffry Thurana in the article The Non-Geek’s Guide To Safely Uninstall Ubuntu From A Dual-Booting Machine The Non-Geek's Guide To Safely Uninstall Ubuntu From A Dual-Booting Machine The Non-Geek's Guide To Safely Uninstall Ubuntu From A Dual-Booting Machine Read More . Unfortunately, when I tried to reboot, Windows failed to start and gave the following details:

File: \Boot\BCD
Status: 0xc0000098
Info: The windows Boot Configuration Data file does not contain a valid OS entry.

Any suggestions how I can get back into Windows and also to be able to boot directly into Windows?

Thanks
Duncan

    you dint  tell your OS .

    well any way these are the official MS instructions for trying repairing the error --

    you have to use the Bootrec.exe tool , 
    heres how , 

    Bootrec.exe optionsThe Bootrec.exe tool supports the following options. Use the option that is appropriate for your situation.

    /ScanOsThe /ScanOs option scans all
    disks for installations that are compatible with Windows Vista or
    Windows 7. Additionally, this option displays the entries that are
    currently not in the BCD store.
    Use this option when there are Windows Vista or Windows 7 installations
    that the Boot Manager menu does not list.

    /FixMbrThe /FixMbr option writes a
    Windows 7 or Windows Vista-compatible MBR to the system partition.
    This option does not overwrite the existing partition table.
    Use this option when you must resolve MBR corruption issues, or when you
    have to remove non-standard code from the MBR.

    /FixBootThe /FixBoot
    option writes a new boot sector to the system partition by using a boot
    sector that is compatible with Windows Vista or Windows 7.
    Use this option if one of the following conditions is true:The boot sector has been replaced with a non-standard Windows Vista or Windows 7 boot sector.
    The boot sector is damaged.
    An
    earlier Windows operating system has been installed after Windows Vista
    or Windows 7 was installed. In this scenario, the computer starts by
    using Windows NT Loader (NTLDR) instead of Windows Boot Manager
    (Bootmgr.exe).

    /RebuildBcdThe /RebuildBcd option scans
    all disks for installations that are compatible with Windows Vista or
    Windows 7. Additionally, this option lets you select the installations
    that you want to add to the BCD store.
    Use this option when you must completely rebuild the BCD.

    Note If rebuilding the BCD does not resolve the startup issue,
    you can export and delete the BCD, and then run this option again. By
    doing this, you make sure that the BCD is completely rebuilt. To do
    this, type the following commands at the Windows RE command prompt:bcdedit /export C:BCD_Backup
    c:
    cd boot
    attrib bcd -s -h -r
    ren c:bootbcd bcd.old
    bootrec /RebuildBcd

      i forgot to mention , you have to launch Command Prompt and then enter the commands in it ..

      here how you should launch CMD ,-
      you have to insert your Windows Installation disc into the drive and boot from it .

      if you dont have one , you can borrow it from a friend 
      or 
      download it from the net and then create a bootable disc or bootable USB with it and boot into it .
      and then click on - start CMD .
