I have this laptop for almost 9 years now and it was given by a Bank (company) and since then I am using it. The problem is now the BIOS switched from Legacy to UEFI but the OS is not booting. I need to turn the Legacy support on from BIOS but I don't know the password, it is first time I need the password because the OS is not booting, it says "bootdevice not found" - and the thing is it tries to boot from network. I need to switch it to USB and in order to do this I need BIOS password again. I have no access to this computer!
I guess I need smc file, as far as I understand. I tried to unplug the CMOS battery but it did not work. I hope you are able to help me I don't want to throw this computer away. It's serial number is [Personal Information Removed].
