Windows 10: Can/Should I enable secure boot?

Built my system myself about two years ago now, and while investigating my system's compatibility with Windows 11, I learned that secure boot is disabled, but is supported by my hardware. Now, I am wondering if enabling secure boot is a good idea, are there any drawbacks or risks of data loss/loosing access? Another question is whether I can enable it properly, as I read that it should have been enabled prior to my Windows 10 install and that it also depends on whether Windows was installed in UEFI or BIOS mode?? Any advice appreciated.TLDR;Can I enable secure boot post Windows installation?Sh

Windows 8 Secure Boot Feature: Not So Secure?

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

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.

Hi ShowMeGirl1

To enable Secure Boot, your PC must have UEFI BIOS and you need to boot your PC into BIOS

Start your PC, on the manufacturers logo screen, there is generally an indication of how to boot your PC into Setup - usually it is F2, or F12 . .

On the Manufacturers Screen, repeatedly press that appropriate key, so your system boots into BIOS

If you do have UEFI, you will see the Secure Boot and legacy Boot options, turn off Legacy Boot (if applicable) and turn on Secure Boot

Also Please Note: to enable Secure Boot, your hard drive must be GPT, not MBR!
