    Windows fails to boot. Can't even boot to safe mode. Help!

    Comodo Internet Security couldn't start properly one day. I uninstalled and restarted. Then reinstalled but failed. It asked me to restart. I was no longer able to boot into Windows after that.

    When Windows started, it went directly into Startup Repair. After about 15 minutes, it stated it failed to repair with the following errors:

    PROBLEM SIGNATURE
    Problem Event Name StartupRepairOffline
    Problem Signature 01 6.1.7600.16385
    Problem Signature 02 6.1.7600.16385
    Problem Signature 03 unknown
    Problem Signature 04 292
    Problem Signature 05 Autofailover
    Problem Signature 06 1
    Problem Signature 07 MissingOSLoader
    OS Version 6.1.7600.2.0.0.256.1

    I tried system restore but failed. The error message was as follows:
    (not exact wording since using another language)
    System restore failed while logging in to restore from the restore point.
    An unspecified error occurred during system restore. (0x80070003)

    I tried twice to boot into safe mode but failed.
    I tried to press F8 rapidly or held down F8 key once computer started . None worked. They simply went straight to the "Startup Repair" loop.

    What's up? How could I fix so it could boot again?
    Using Windows 7. Thank you.

    Masterton,

    Can you boot the Win7 disk, Command Prompt, chkdsk /f

    Any bad sectors?

    I assume you don't have a backup image.

    In the future (as a reference after this) please consider at the very least using one or two programs (or both like me) to make regular registry backups. If @Brian K concerns are as assumed, you have no backup image.

    Not that it's a failsafe but for Windows 7 and on my machines Windows 8.1, having a ready backup supply of the registry often times at least got me booted up even if in a semi-crippled GUI where there's more freedom to reorganize and recover from unexpected boot issues when no backup image is available or one fails.

    Boot from the Win7 disk
    At the "Install Windows" screen press SHIFT F10 to get a command window

    Not from Win7 disk. I ran chkdsk from command prompt after repeated startup repair failure. The operation was complete. No bad sector was found.

    No backup image. Actually I am trying to help a friend to fix boot issues of their laptop.

    I created a bootable Windows 7 USB drive using Rufus with the following settings:

    Partition scheme: MBR.
    Target System type: BIOS or UEFI-CSM.
    File System: NTFS.
    Cluster Size: select the 4096 bytes(Default).

    Then I ran the startup repair from the USB drive but failed. The error was slightly different.

    PROBLEM SIGNATURE
    Problem Event Name StartupRepairOffline
    Problem Signature 01 6.1.7600.16385
    Problem Signature 02 6.1.7600.16385
    Problem Signature 03 unknown
    Problem Signature 04 -1
    Problem Signature 05 ExternalMedia
    Problem Signature 06 1
    Problem Signature 07 NoOsInstalled
    OS Version 6.1.7600.2.0.0.256.1

    What else could I try to fix it?
    I still want to fix if possible.

    If not, what is the best way to backup all program data/settings and files from the laptop in this case? Thank you.

    I see you got the UFD to boot. I use the Boot Menu, not Boot Order.

    When you have had several Startup Repairs fail the outlook isn't good. But try the above suggestions. If the laptop remains unbootable you can at least copy off the personal data files to a USB external HD.

    Edit... You mentioned F8 didn't get you into Safe Mode. Is F Lock enabled?

    If you want better help, you need give more information. Right now I only understand that it's Win7.
    But don't know what computer, was Win 7 originally there installed when the computer was purchased ie purhased as a new one.
    Of it depends if there BIOS or UEFI boot, is there MBR or GPT, etc.
    But it seems to me that there's nothing to improve/repair/fix there.
    The only way is to save your files to any other place and make a clean install (Do you know what is a clean install?).

    Sometimes getting into Safe Mode is like hooking a fish. Keep trying. Sometimes it's taken me a dozen times or more to clickedy click clik on F8, F11, F2, Esc or whatever the key is to get into Safe Mode. You gotta start clicking at the right time, continue clicking & then stop at the right time.
