Bricked laptop - Lenovo B50-80

[zeioth]

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'


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:


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?

Secure boot is not going to let you use that boot loader without disabling it first. That is secure boot doing its job. Set bios to legacy mode.

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.

Fagetti thank you for your response. There are no passwords involved.

So am i right you cant boot from any usb? Not even windows installer for example?

You can then use this method
