    Whenever I start my laptop Asus G74S it goes from the Asus splash screen to the startup system repair it runs it for a while then says it cannot be repaired. i've tried to system restore and what is suggested here (http://www.sevenforums.com/tutorials/139576-startup-repair-infinite-loop-recovery.html) and it did not work. I'm wondering if I need to just wipe the hard drive and start fresh or is there anyother fix to this.

    I have windows 7 64 bit

    Try to run the Startup Repair by booting from the Windows 7 disc and then copy the report at the end into your next post. It should give us a clue as to the problem.

    I can't access the boot menu during start up. It goes straight to the repair startup everytime I try to hit the boot menu key. If i'm missing something I'm sorry. All your help is appreciated.

    Ok, have you got a Windows 7 disc, if not you can make your own Repair disc to boot the machine into the Recovery Environment, you can do this on any Windows 7 PC as long as it is the same bit rate (32 or 64bit) as yours.

    Go to Control Panel and select Backup and Restore. In the left hand pane select "Create a System Recovery disc" and follow the prompts.

    Post back when you have either of these discs.

    3AM here so be back in the morning.

    1.Put the Windows 7 installation disc in the disc drive, and then start your computer.
    2.Press a key when you are prompted.
    3.Select a language, a time, a currency, a keyboard or an input method, and then click Next.
    4.Click Repair your computer.
    5.Click the operating system that you want to repair, and then click Next.
    6.In the System Recovery Options dialog box, select Startup Repair.

    Let the repair run and do not touch any keys until it displays a result. Select to view the report and put it into your next post.

    NOTE: If it does not boot from the disc you will have to boot into the Bios first and change the boot order so that the CD drive is in 1st position.

    According to the repair report the BCD store has a problem, follow this guide to rebuild it:


    You can rebuild the BCD store by using the Bootrec.exe tool in the Windows Recovery Environment. To do this, follow these steps:
    • With the PC turned on, get your Windows 7 installation or Recovery DVD and put it into your CD drive and restart the PC.
      NOTE. You may need to boot into the Bios and change the boot order so that the CD drive is in first position if it does not boot from the CD.
      Bios Boot Order Guide
    • Press a key when you are prompted.
    • Select a language, a time, a currency, and a keyboard or another input method, and then click Next.
    • Click on Repair your computer.
    • Click the operating system that you want to repair, and then click Next.
    • In the System Recovery Options dialog box, click Command Prompt.
    • Now type bootrec.exe and press Enter. This will rebuild the boot configuration data and hopefully fix your problem.
    • If Bootrec runs successfully, it will present you with the installation path of a Windows directory. To add the entry to the BCD store, type Yes . A confirmation message appears that indicates the entry was added successfully.
    NOTE: If Bootrec cannot locate any missing Windows installations, you must remove the BCD store, and then you must re-create it. To do this, type the following commands in the order shown below: (Remember to press ENTER after each command) Make sure you add spaces so what you type is identical to the commands shown below.
    NOTE: If Windows is not installed on drive C: you must substitute C: with the correct letter in the following commands.



    • bcdedit /export C:\BCD_Backup
    • c:
    • cd boot
    • attrib bcd -s -h -r
    • ren c:\boot\bcd bcd.old
    • bootrec /RebuildBcd
    Now type Exit and press Enter and reboot the PC.

    I did what you said. It gave me this message when I restarted.

    A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source.

    File: \Windows\system32\winload.exe
    Status: 0xc0000428
    Info: Windows cannot verify the digital signature of this file

    I inserted the windows 7 disc and went to repair windows and got

    System Recovery Options
    Windows found problems with your computer's startup options.
    Do you want to apply and restart your computer?

    Details:
    The following startup options will be added:
    Name: windows Recovery Environment {recovered}
    Path: Recovery\8cb2d9b4-7c05-11de-842e-b4611d44fefa\Winre.wim
    Windows Device: Partician=C: (244192 MB)

    A copy of your current boot configuration data will be saved as: C:\Boot\BCD.Backup.0001

    Ok, that is an important file without which Windows cannot load, it could be corrupted or infected.

    Go here: System File Checker from the Recovery Environment
    And follow the instructions to scan the integrity (and repair) a specific file.
    Substitute the file zipfldr.dll with winload.exe in the command line. Be careful how you type this and make sure you leave spaces so it is identical. Also, be sure you use the correct drive letter as per the instructions

    Let me know what it reports.

    Ok, follow the same instructions I gave the link for and do a full SFC on the system.

    If that comes up clean then run the Startup Repair again, the Startup Repair can only fix one problem at a time so sometimes it needs to be run three or four times before it completes.

    Windows Found corrupt files but were unable to fix some of them
    Details are included the CBS.log


    I assume you want the CBS log?

    The CBS log would be good but you won't be able to get to it with a non-bootable machine. This is looking more like an infection causing file damage.

    You can try running SFC multiple times but if it is an infection causing the corruption then the repair will not last.

    Would you consider doing a clean install of Windows as that may be the fastest way out of this. Have you got all your important data backed up?

    Another possibility is that the problem is being caused by a failing hard drive so running the manufacturer's diagnostics first may save time in the long run, no point re-installing Windows if the hard drive is faulty.

    Identify the make of your hard drive and then use one of the links below to get the manufacturer's diagnostics for ISO (CD) not the one for Windows.
    When the download is complete right click the file and select Extract Here and burn the image to a CD.
    In Windows 7 right click the extracted file, select Open With, then select Windows Disc Image Burning Tool then follow the prompts. For all other versions of windows (if you do not have an ISO burner) download this free software. ImgBurn
    Install the program and start the application. Select the top left hand option to burn image file to disk and then on the next window click on the small yellow folder icon and browse to the file you have downloaded from the links below. Then click on the two grey discs with the arrow in between (bottom left) and leave it to complete the operation.
    Boot the PC into the Bios setup and set the CD/DVD drive to 1st in the boot sequence. Insert the disk in the drive then reboot and the disc will load into dos.
    Excelstore Use EStest CD image
    Hitachi/IBM Use the Drive Fitness Test - CD Image.
    Seagate, Samsung, Maxtor & Quantum Follow links for SeaTools (For DOS ISO image)
    Western Digital
    Toshiba/Fujitsu
    If you have a Toshiba/Fujitsu hard drive I would suggest the use of the diagnostics from the Seagate link as this will work on all makes of drive and on any OS.
