    Reboot loop issue


    I have a Windows 7 Desktop which is experiencing the following issues
    - Reboot loop upon boot. It will load the BIOS screen and then immediately load the "Windows Error Recovery" screen asking me to either run "Startup Repair" or "Start Windows Normally". Choosing either option will lead to a reboot loop with the same scenario.
    - During normal usage, it will reboot itself and be stuck in the reboot loop above. This occurs rarely.

    I managed to boot to Safe Mode and run sfc \scannow and chkdsk. However, there are no errors.

    Update:
    - Boot with only system drivers selected does not work as well, results in reboot loop.
    - "Advanced Boot Options" > "Repair Your Computer", results in reboot loop.
    - I have tried to boot using a USB drive containing Windows 7 and another containing Ubuntu, both doesn't work and displays the same reboot loop symptoms.
    Does this mean this PC is dead?

    Are there steps I can do to resolve this issue ? Cheers !

    When you booted from USB device, did you alter the boot priority in BIOS, to boot from USB first? That could be why it did not work for you.

    Yes, I did change the boot priority in the BIOS. I tried the bootable USB on my laptop and it worked.

    Does the primary disk drive show in BIOS? It could be that the HD or the HD controller has had it.

    Do you see the windows Logo at all? If you get the Windows logo after the BIOS screen, then it is more likely an issue with the Boot Manager.

    Yes, the primary hard drive shows up in the BIOS. I set it to a lower number in terms of priority.

    Hmm yes, I see the Windows logo. Afterwards the reboot loop occurs. What can I do to repair the boot manager ?

    Cheers.

    This command cannot be found in safe mode CMD. Is it available only in the recovery environment?
