This is scary (Bitlocker), sent me to Wikipedia to look up Bitlocker.

Can you turn Bitlocker off after turning it on and get your system back?

Now I am even more scared to ever get a computer with MS-Windows!

One think on my mind is if I need a new motherboard, would it have the undesired Secure Boot?  I guess I'd have to ask the seller and look on the motherboard manufacturer's website (MSI, ASRock, Asus, Gigabyte, or other).

I have no Secure Boot now.

I am trying to set up UEFI to boot my FreeBSD and NetBSD installations, and later, Linux.
