Windows 10: Enable Secure boot Windows 10 don't start

Hi,I need to enable bitlocker on a computer that is already installed and the BIOS settings during the install was Secure Boot disable and Startup mode Legacy.

When enabling Secure Boot it force the computer to use UEFI Only but windows don't boot with that setting. I only get to the Windows Boot Manager, I can select my HDD but it don't boot.

Any idéa what I can do to start Windows with Secure Boot enable?

Thanks

Edit: its a Lenovo laptop

Windows 8 Secure Boot Feature: Not So Secure?

So Linux is switching to secure boot also? Or they have to because of UEFI?

 

Windows 8 Secure Boot Feature: Not So Secure?

• Linux
• Linux
• Linux
• Linux
• Oh and OSX

Here is a statement from a Kernal Developer at Red Hat:

I'm not sure this exploits the legacy BIOS but rather it exploits the legacy boot method on MBR drives, injecting a signed key before the OS boots, which you are correct in that it has nothing to do with Windows 8. And the simplest fix would just be to require boot drives use GPT when Secure Boot is enabled in UEFI.

 

Windows 8 Secure Boot: Designed to Lock Out Linux?

from the article:

translation:

so if an oem manufacturer wants their firmware to enable secure boot with windows, it will be controlled and mandated by microsoft.

in order to allow secured boot, they will need to follow msofts rules. since the signed os bit is part of UEFI anyway, i'm not sure what rules microsoft will impose, but this is fancy speak trying to hide the fact that they WILL mandate and control firmwares that enable secured boot for windows.

not saying that does or doesn't make sense, they just deliberately tried to hide that point.
