    This happened after motherboard replacement. The instructions in Method 2 worked. So simple when you know how. Thank you.

    I had to replace the motherboard on my laptop computer. Method 2 worked to remove the yellow triangle with an exclamation point in it. Thank you!

    I attempted the command line method and to no avail. I am trying to access data on a drive from another PC and I was able to view the data once when I first removed the hard drive from the old PC. Afterwards, it had stopped working, most likely due to a process preventing access via BitLocker. Would resuming the drive (enabling bitlocker) on another PC cause issues and data loss?

      At your case you have the following options:
      1. To unlock the drive bye Entering the BitLocker key (if you know it) and then to Disable Bitlocker.
      2. Put the drive back to the PC where Bitlocker was enabled and check if you can view the Data. THen DIable Bitlocker.
      (p.s. See this article for instructions.)

    Wow, you are really helpful!

    You see, after I attempted to reset my pc with a BitLocker encrypted drive, I wasn't able to access my stuff anymore without entering my recovery key. This was, of course, a hassle, because it was my second drive I would put my downloads, documents, and other stuff that I didn't need on my OS drive. I found a temporary fix, but then it showed the triangle. This fix would also need to be done every time before I shut down my computer. Not very user friendly… in settings it wouldn't allow me to decrypt a single drive by itself either. I'm using the windows 11 insider edition, so I am not sure if that is something they deprecated since windows 10. Anyways, after the triangle I ended up searching soo many articles! I almost lost hope until I stumbled upon this one, because many of them had the same, useless fixes that did no good. You are a lifesaver!!! Thanks to you (the publisher of this article :D), I am now able to use my computer as I wish to 🙏🙏🙏 Many thanks to you!
