Windows 10 Computer Won’t Boot After Power Outage
By Timothy Tibbettson 07/05/2023 |
If you left your computer on during a storm or power outage and found that you can't boot, there are a few possible solutions to get your computer started.
1: Hold Down the Power Button
Often overlooked, we've seen computers go into hibernation, but the user thinks the computer was shut down during a power outage. Hold down the power button for 15 seconds. If nothing happens, press power one more time.
2: Boot From Safe Mode
This step has more possibilities than most, but it requires you can get Windows to boot into safe mode. Often, after a major incident like a power outage, Windows will automatically try and repair your computer while booting into Safe Mode. If you're not prompted to repair your computer, don't shut down because we can run some diagnostics from Safe Mode.
Another option is to use Ultimate Boot CD to get to a command prompt. It's a bootable ISO image with all the diagnostic tools you could need.
Run Microsoft System File Checker, a useful, built-in utility that can scan for, and restore, corrupted files in Windows.
3: Boot From Windows DVD or Thumb Drive
Next, we might try booting from Windows installation media. Your best bet is to go to Advanced and then choose Startup Repair. This step is perfect if you couldn't get into safe mode above and start repairs.
Worst case scenario, you should be able to get to the Command Prompt from the Windows media or any bootable diagnostics app. Here are a couple of possible fixes if you're at the Command Prompt.
Run Microsoft System File Checker
Rebuild your BCD by typing in bootrec/rebuildbcd
If you see
Total identified Windows installations: 1.
Add installation to boot list? Yes/No/All:
Choose Y or Yes.
If you see
Total identified Windows installations: 0
The operation completed successfully
Then type in bcdedit /import f:\01.bcd replacing F with your drive and the correct BCD name.
