Help! My Windows 11 PC Won't Boot After a Power Outage

Asked by TechieTommy92
I recently updated to Windows 11 about two weeks ago. Today, the power went out while I was using my computer, and now it won't boot at all. It keeps cycling on the BIOS splash screen and then just restarts repeatedly. I checked the BIOS, and it does recognize the boot drive. I'm comfortable navigating the BIOS and use the command line. Any ideas on how to troubleshoot this? Why would a power outage cause my system to act this way?

I've experienced a similar issue before. In my case, I had to wipe the drive, repartition it, and then do a clean installation of Windows through USB. You can use a tool like Ventoy to make the process smoother. Just make sure you've backed up any important data before wiping!

It sounds like your computer might have been in the middle of a crucial update when the power went out, which can really mess things up. I suggest trying to boot from a USB and accessing the recovery environment. Once there, you can attempt startup repair, uninstall any recent updates, or restore from a previous save point. If you're having trouble getting to recovery mode, just power it off three times in a row to force it into recovery mode.
