Easy Fix for Windows 11 24H2 and SteamOS Corrupted Dual Boot for Steam Deck OLED and Steam Deck LCD

The latest Windows 11 24H2 was released October 01 2024. Unfortunately there is an issue with this version of Windows 24H2 and SteamOS.

Once Windows 24H2 is installed, you can't boot back to SteamOS. The GPT gets corrupted and the partitions are "lost". Booting to SteamOS will result in a grub error and it can't proceed further as the partitions needed are "lost". This will also result in Windows not booting up anymore.

I've encountered this issue several weeks ago when testing 24H2. It was an easy fix to restore a working copy of the corrupted partitions.

I thought it was just a fluke on my end but as soon as 24H2 became available publicly and users are reporting the same issue then I knew that it is indeed a bug.

Check out the video guide for my troubleshooting steps and how I was able to fix and restore the partitions to a working state!
