Good morning everyone and thanks for the help in advance.
I'm writing you today because of an ugly issue with BitLocker. (on windows 11)
A couple of years ago I have got my computer, a Lenovo laptop, reset by their official customer service in Spain (where I was living) and when they returned it to me it had a local account only, named LENOVO. I've kept on using that account since then, without logging in with any Microsoft account because I have to admit liking that "password free" life, and my data are very important, but privacy is not a problem for me since my computer remains home.
I've now decided to upgrade a little, so I’ve changed the internal SSD with a bigger one (its perfect compatibility was certified by the vendor), I’ve installed windows back. Everything was perfect till I’ve tried connecting my old SSD externally with an SSD USB case. When I did it, my computer asked me for a BitLocker key, even I’ve never requested any encryption.
Since I don't have this key, I’ve tried mounting the old SSD back into my laptop, assuming that being in its original place with no hardware changes it will work back without problems. For my surprise, when I booted the laptop, it still asked me that BitLocker key, with no way out.
Now, I'm sure that I didn't use any Microsoft account as Windows user after the customer service restored my laptop and I'm pretty sure the only Windows user in it was that local one named LENOVO.
I've checked online and I’ve found out that, since my computer at boot says: to find your key "try your work or school account" it means that the BitLocker key is stored in an institutional account (school, university, corporations, or ...)
I've started thinking and I could come up with two possibilities (or maybe you can point out more).
1 the Lenovo customer service, despite of creating a local account for the laptop, in some ways registered the BitLocker key under some institutional account of their own (theoretically possible?)
2 after I got my computer back, when I’ve logged in Microsoft Office using my university account, windows automatically transferred the BitLocker key in that account.
Since I'm having problems contacting Lenovo customer service (maybe you can give me some advice about how to do that too?), I'm trying to check on my university account.
The problem is that even though I could successfully login in office apps, if I try to check the page "aka.ms/aadrecoverykey", after inserting email and password (which are correct, since I could login with office apps), it asks me a 2-step verification, sending an SMS to my old Spanish phone number which I do not possess anymore.
So, I'm stuck, unable to access my data (all my recent research and job documents are in that SSD).
Please, help.
