So now I'm feeling a bit lost about what to do with the laptop of my friend. This is what happened: https://www.dell.com/community/Windows-10/BitLocker-need-a-key-but-I-never-installed-it/td-p/6019486 I tried the suggestions in the link but none of them worked for me. Then I tried Bitleaker https://github.com/kkamagui/bitleaker but it seems the BIOS of the laptop is too new, perhaps I could try to downgrade to the oldest available and retry, what 's your opinion? Got a thread opened there too: https://github.com/kkamagui/bitleaker/issues/8 Honestly I don't know how to proceed and if there is a way to recover his data .................... :( I really need some suggestions
