I have aspire 3 a315-34
I installed linux alongside windows and used it for a long time without going back to windows. now I opened windows once and in the next time I tried to boot the laptop, I got "Error: verification failed (0x1a) security violation"
I restarted the PC and this time I got password request, I tried 3 times things I thought might work, and after that failed, it ask me for the "Enter unlock passwordkey"
I have no idea what this key might be. I have this PC for years now. what am I supposed to do?
