I recently set up a dual boot system, and now my Windows 11 activation has stopped working. My PC came already activated when I bought it, so I don't have the activation key to help with this issue. I've spoken with Microsoft support, but they couldn't provide a solution. I really need help getting this sorted out. The error code I'm getting is 0xC004F211. I tried using the option "I recently changed my hardware," but that didn't solve the problem either.

Have you tried hitting `Win + R` and typing `slui 4`? It sometimes helps with the activation issue. Just an idea since it worked for a few people before.
Are you dual booting two Windows systems? That could explain why one isn’t activating properly. If it's not the case, it might be worth trying to see if your changes to the disk setup are affecting the activation.
Nope, my second boot is Cachyos, not another Windows.
Tried that already, but it didn't help when I contacted support.
