  • Please indicate whether you can or cannot open the windows advanced troubleshooting menu on the computer.  If you can there should be options for system restore, startup repair, startup options, command prompt, reset with save files, reset with remove files, backup image.

    1) When you power on the computer what do you see and what do your hear?

    2) Is the computer a desktop or notebook?

    3) What was the error message and what was the error code?

    4) Find a flash drive that you can format ( > or = 8 GB)

    5) Create a bootable windows 7 iso:

    6) Find the keyboard key to boot to the bios boot menu:

    7) Insert the bootable windows 7 iso into any USB port

    8) repetitively click the applicable keyboard key to open the BIOS boot menu

    9) If it is a custom computer open the BIOS to temporarily change the BIOS boot order so the the USB drive is on top.

    10) Select external USB hard drive

    11) It may take 5 - 10 minutes for the iso to load while viewing the Windows icon

    12) Select language, time, currency, and keyboard, or click next

    13) Click torubleshoot

    14) navigate in the the windows advanced troubleshooting menu to system restore

    15) select the oldest restore point.  Try every restore point moving towards the most recent one.  If all restore points fail or if there are no restore points move to the next step.

    16) try startup repair.  If startup repair fails move to the next step

    17) command prompt > Administrator:X\windows\system32\cmd.exe > X:\sources>

    18) type:  sfc /scannow

    19) type chkdsk /r

    (this may take several hours to complete)

    20) reboot

    21) report the results of each step into the thread.

    22) If there are any problems please use a camera or smart phone camera to take pictures and post images into the thread.

  • Hi,

    What is the error when you boot the machine?

    Why did you think the AVAST is the root cause?

    Since you can't boot into Safe Mode, it is suggested that you can use the repair media to do a startup repair, please refer to:

    If startup repair can't help to fix the boot problem, it is suggested that you insert the installation media and fix the corrupted system by doing a clean install. Remember to backup the files before you format the drive.
