Microsoft secured my files! (lemmy.world)

Back in January Microsoft encrypted all my hard drives without saying anything. I was playing around with a dual boot yesterday and somehow aggravated Secureboot. So my C: panicked and required a 40 character key to unlock.

Your key is backed up to the Microsoft account associated with your install. Which is considerate to the hackers. (and saved me from a re-install) But if you've got an unactivated copy, local account, or don't know your M$ account credentials, your boned.

Control Panel > System Security > Bitlocker Encryption.

BTW, I was aware that M$ was doing this and even made fun of the effected users. Karma.

Could you elaborate?

luks-cryptsetup-backup

If you encrypted your disk/partition, the lock is stored in the luks header. But if that one is broken, you cant decrypt anything even if you remember your key and all data is lost.

Thanks!
As I understand it this shouldn't concern me if my backups are full disk images via Clonezilla, as those should already include the LUKS header, correct?

  • Don't get baited into back-and-forth insults. We are not animals.
  • Leave remarks of "peasantry" to the PCMR community. If you dislike an OS/service/application, attack the thing you dislike, not the individuals who use it. Some people may not have a choice.
  • Bigotry will not be tolerated.
    • 3. Post Linux-related content
  • Including Unix and BSD.
  • Non-Linux content is acceptable as long as it makes a reference to Linux. For example, the poorly made mockery of sudo in Windows.
  • No porn, no politics, no trolling or ragebaiting.
    • 4. No recent reposts
  • Everybody uses Arch btw, can't quit Vim, <loves/tolerates/hates> systemd, and wants to interject for a moment. You can stop now.
