Windows 10: UEFI Secure Boot questions

My laptop has Windows 10 with Secure Boot enabled in my UEFI firmware setting and my question is, can Secure Boot still protect booting from a malicious OS or tool (from a bootable USB stick) even when using the F12 Boot Menu Options prompt?

I have a Dell laptop, which uses the F12 key to bring up the Boot Menu Options.

BitLocker is also enabled.

Another question would be, is that I reinstall Windows 10 OS from time to time and I plug in my USB bootable Windows 10 flash drive, and how come Secure Boot will not react to this? It should detect that I am booting another Operating System. Am I correct?

With those questions being asked above, I did set a password for the UEFI so nobody would change the firmware settings.

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.
