BitLocker was created to protect you in the event a thief steals your computer. Someone with physical possession of a computer can tamper with it in ways that a hacker cannot. When Windows detects tampering, it locks the computer with BitLocker.
Sometimes, without intending harm, computer users do things to their computers that trigger BitLocker. So the real solution for your situation is to think about changes you have made to your computer which could be triggering BitLocker, and undo those changes, if that's possible.
Here are some common events that cause a computer to enter BitLocker recovery mode when starting Windows. (This is not a complete list.)
- having the CD or DVD drive before the hard drive in the BIOS boot order
- upgrading Windows from a CD/DVD or a mounted ISO
- docking or undocking a portable computer
- making changes to the NTFS partition table on the disk
- making changes to the boot manager
- turning off, disabling, deactivating, or clearing the TPM
- upgrading the motherboard to a new one with a new TPM
- upgrading critical early startup components, such as a BIOS or UEFI firmware upgrade
- moving a BitLocker-protected drive into a new computer
These are all things that a thief can do to break in to a computer.
