Yeah, but it seems we're out of luck

This was the exact same situation I experienced with my old Surface 6. Started to look into Linux firmware on Surface devices and deactivated secure boot because it wouldn't boot Ventoy at all and do nothing, so I figured to try again with no secure boot. It still didn't work so I turned it on again, but was then greeted with this Bitlocker screen which I didn't even know it had activated up until this point. I set up a local account so I had no key to reset or something and was literally not able to do anything besides reinstalling the entire system.
Luckily I had nothing important on it lol
Weirdly the activation was saved on the MS servers so I didn't need to do that again at least (was a preinstalled system so I wouldn't have known the activation key anyways, I thought "When it doesn't work I'll switch to Linux fully because I'm not paying for that garbage system").
After I updated Ventoy I was able to boot again even with secure boot on, there seems to have been an issue with that specific version.
I had Windows on my device since I bought it (around 2018) only upgraded to W11. It never mentioned anything about Bitlocker before this incident so if I had important stuff on it it would have been so over. Well, never save important files on Windows without backup is what I got out of it
This caused me literally bigger problems than my switch to Arch Linux after having only used Windows the entire time xD
Every time I read something new about the new Windows. I'm really glad I've switched to Linux and figured how to set up, use and debug it already. With this knowledge I never want to go back. Even PC Gaming is no problem anymore with Proton, Lutris etc. The only thing I needed to watch out for was to get an AMD graphics card (NVIDIA is slowly getting there too hopefully), but I needed a new PC anyway so it was the perfect time
I wanted to make the same joke! Nice that you noticed it too lol
