Cannot start windows after power outage

Anonymous

There was a momentary power flicker at my apartment while I was not home as a result of a storm. When I go to start my PC, it attempts automatic repair before going to a blue screen that says "Startup Repair couldn't fix your PC", and offers to either shut down or go to advanced options. In advanced options I have tried simply continuing and restarting but those do not work, and in troubleshooting I have attempting resetting but it says there's an issue and it cannot reset. Then in advanced options I see "startup repair", "startup settings", "command prompt", "uninstall updates", "UEFI Firmware Settings", "system restore" and "system image recovery". None seem to do anything. I also went into the bios during attempted restart and it seems to detect my drives and components fine, so nothing was fried.

    Hi Kyle. I'm Greg, 10 years awarded Windows MVP, here to help you.

    The most common result of power surges or cuts is file system damage which is fixed by Disk Check. It doesn't sound like it's automating that or it would warn that it can take awhile. So I'll include it in all possible fixes working from WinRE Repair Mode or bootable media.

    Use whichever method works in this link to get into Repair Mode so you can try the necessary repairs or do a Reset:

    https://www.tenforums.com/tutorials/2294-advanc...

    Easiest is to force shutdown by holding in the power button. Do this twice. The third time you power on it should start into Repair Mode. Once in the Repair Mode try the numbered steps below.

    It may be necessary to create bootable media on another PC to access Advanced Startup Options to try repairs, a Reset or do the Clean install. The bootable media has it's own set of files so that repairs or Reset might work better, doesn't require a password, and you'll have it to if necessary do the vastly superior Clean Install.

    To create Windows 10 Installation Media on another PC install Media Creation Tool and follow the directions here: https://www.microsoft.com/en-US/software-downlo...

    Insert media, boot it by powering up PC while pressing the BIOS Boot Menu Key given here: https://www.sysnative.com/forums/hardware-tutor...

    If the media won't boot you may need to enter BIOS/UEFI Setup (pressing key given in chart in link above) to turn off Fast Boot or Fast Startup first.

    Choose the boot device as a UEFI device if offered, on second screen choose Repair Your Computer, then Advanced Troubleshoot Options, then:

    1. Try a System Restore, working backward.
    2. If that fails try Uninstall Updates as far back as necessary to see if this was caused by an Update. If Steps 1 or 2 get it started then immediately check Windows Update for Updates and hide them using this tool: https://www.tenforums.com/tutorials/8280-hide-s...
    3. Open the Command Prompt to:

    a) run System File Checker: https://www.wintips.org/how-to-run-sfc-offline-...

    and DISM: https://www.ubackup.com/windows-10/dism-offline...

    b) run a full Disk Check: https://www.windowsdigitals.com/how-to-run-chkd...

    c) trigger Safe Mode with Networking (for internet) or Safe Mode following Option 3 here: https://www.digitalcitizen.life/4-ways-boot-saf... to roll back Updates & Drivers in Windows Update History, update your drivers from the PC/Motherboard manufacturer's website and diagnose further with these steps: https://www.howtogeek.com/164876/how-to-use-saf....

    You can also create a new Local Admin account to replace yours: https://www.isumsoft.com/windows-10/3-ways-to-c...

    d) To replace the User account try to enable the built-in elevated Admin account from Option Five here:

    https://www.tenforums.com/tutorials/2969-enable...

    Boot into this emergency Admin account (leaving password box blank) to create a new Local Admin account:

    https://www.isumsoft.com/windows-10/3-ways-to-c...

    Sign into the new Account, make sure it works correctly, if so move your files over via C:\Users, when ready delete the old account and change the new one to your MS Account if desired in Settings > Accounts > Your Info > Sign in with a MS Account instead.

    1. If those fail then go back to Troubleshoot Options to do a Reset. Make it a deep clean reset to set up a new account, with Cloud option to download fresh installation files so it doesn't use old onboard files that may be corrupted.
    2. If that fails choose Install Now, then Custom Install, then at the drive selection screen delete all partitions down to Unallocated Space to get it cleanest, click Next to let it create needed partitions and start install - this makes it foolproof. Everything needed to Clean Install is here: http://answers.microsoft.com/en-us/windows/wiki...
    3. If you have files that aren't backed up you can use the same bootable media to try to rescue your files using these methods: http://answers.microsoft.com/en-us/windows/wiki...

    Your files should be backed up at all times if you value them at all. In the Clean Install tutorial in Step 5 I give the best methods to back up.

    I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.

    I do not see anything referring to "unallocated space". It is simply "Drive 1 Partition 1" going partition 1 through 5. It has done this for both my SSD and HDD. On each of them there is a primary partition, MSR reserved partition, system partition and two recovery partitions.

    If you're at the point where you want to do a Clean Install from the bootable media in Step 5 above, then Make sure during the booted install to unplug all other drives, boot the media as a UEFI Device, choose Custom Install, delete all partitions down to Unallocated Space to get it cleanest, choose the Unallocated Space, click Next to auto-create and -format the needed partitions and begin install - this makes it foolproof.

    After install expedite all Windows Updates including Optional until no more are offered. Then import any drivers from the PC maker's Support Downloads web page for your model that are newer, or branded instead of generic. The most basic thing we need to learn to maintain a PC is how to keep the latest manufacturer's drivers current. Windows drivers are rarely enough.

    Keep me posted on your progress as I will be here to help until the case is resolved.

    Nothing suggested has seemed to work. I cannot reset as no matter how I attempt to go about a reset it immediately just says "there was a problem resetting your PC" and nothing happens. The chkdsk commands did seem like it discovered and dealt with some type of system corruption, but still no change. I did notice however while messing with the windows installation program via a USB with windows on it that my drive was partitioned 5 ways? It was not like that before the power outage. I would post pictures if the site allowed it. But anything I attempt to do in ways of resets/etc. won't go through.
