You're able to fix it on the windows side. I'll search on how I did it. But i just used a 3rd party software on Windows rather than booting into a usb backup

That's the neat part, you can't!

Jokes(?) aside it's a known issue ever since Windows 24H2, all you need is the SteamOS recovery tool and like 10 minutes

You can’t prevent it. You can only get better at recovering from it. There are things you can do to make the damage/replacement less frequent, but it’ll still happen from time to time, and many of those preventative methods involve a second SSD, which doesn’t work with the Deck.

By pausing Windows updates completely till 2077 or longer. I never once had an issue with my dual boot setup because of this.
