Hi, after I reinstalled GRUB I have the next problems with my Lenovo B50-80:


    1) When I try to boot into my OS, I recieve the blue screen 'Security violation':

    2) I can't boot from any media (DVD nor USB), I recieve the error 'EFI boot failed'
    54095i6AC8CDB35B14053E

    3) On my bios, I can't disable secure boot . Secure boot status always remain enabled, no matter what I try.

    4) Factory reset shows the same blue screen: Security violation

    5) If I extract my hard disk or I insert a different hard disk into my laptop I recieve the bios error:
    6730fa0f-bf41-4d7d-833f-ec6ab6347261

    6) If I try to boot my laptop's hard disk in another computer, it doesn't recognize any partition, nor can be read/written.


Looks like I've accidentally triggered the secure boot protection of my computer. Someone with more experience could tell me how to fix it, please?

If I go into legacy mode, save the changes, and reset:

1) I recieve the next error when I try to booy from UDB/DVD

2) When I go to the bios again, the settings were automatically resetted to UEFI.

I dont know anything about this issue but am sure atleast bios reprogram will fix it 99%. I let more knowing people answer first if they can help you fix it but if everything else fails i can help with reprogram bios chip. I guess this is ok if your issue doesnt involve removing bios or supervisor password which is denied in this forum.

Update: I was able to save the hard disk after inserting it in another PC with secure boot disabled. But the laptop still won't allow allow me to boot any USB/DVD/HDD/SSD, so, it's still bricked.
