I recently had the power cut off suddenly, and the computer subsequently couldn't find the boot drive. I went into the UEFI and tried selecting different partitions, hoping that some kind of boot process was stored there. I found one that seemed to have a boot record, and it dropped me into a Windows recovery prompt, despite me having nuked Windows long ago.
I was able to use a Linux install drive to mount the boot partition, drop the necessary boot files in the respective folder, and I could even clean up the leftovers from Windows. Drive now boots fine, and I learned something.
Let's see Windows do any of that. Moving to Linux was the best thing I've ever done for my computer.
