The Problem

I dual-boot multiple Linux installs along with Windows. At some point, possibly coinciding with an update to one of my Linux installs, my Windows partition failed to boot with a bluescreen error showing a WHEA_UNCORRECTABLE_ERROR error message. I tried booting multiple times with no success.

Most info I found online about this error seemed to indicate that it was related to hardware issues, but I hadn’t made any hardware changes recently and my Linux installs continued to boot and work fine.

The Fix

My boot setup is a bit unique since the Linux partition I use primarily isn’t the one that manages the bootloader.

To fix the problem, I booted into the Linux install that controls the bootloader and ran sudo update-grub.

After doing that and rebooting, my Windows partition booted and worked fine without any further changes necessary.
