BitLocker

Hello
After connecting a drive with Linux on port USB on my PC HP 250 Laptop , I cannot boot with Windows
I get a message asking me to enter the key because my drive is locked with BitLocker
I cannot connect to my account Microsoft (Message too many tries .....)
Has somebody a good idea for me ??
Thank you

If you did not keep record of your BL key and do not know your MS password, the only thing I can suggest is to attempt to recover your MS password online (IF you have 2 step verification set up in your MS account) Recover your account
Your BL key should be in the MS account
Otherwise, all I can suggest is a clean install on the drive using a local account..
