UEFI Vs. Bios. What is the truth ?

[davexnet]

UEFI and Secure Boot was sold to the public as being a safer, more secure system.

But in general, it seems to be open to abuse and attack more than the old BIOS ever was.
Lenovo laptops themselves abused a UEFI facility to load an analytics driver during the boot
that kept coming back after the user uninstalled it.

The list goes on and on, loads of articles on the internet detailing similar problems and issues.

UEFI is far from infallible, but it has the capability of being way more secure and flexible than Legacy Bios ever has been.

Manufacturers do have inner tracks to loading things, but that is often their prerogative - it is meant for easier customer service.
But, it IS possible to wipe Lenovos so everything is gone, Just like it is easy enough to remove a secure booted Windows recovery partition - just wipe it * and put a Linux distro on there, and then rewipe it and put your Win image.

Legacy is just that - the past.

* assuming secure boot disabled, and bios/uefi firmware admin password known

Im using a dual boot (windows/Linux) with 2 drives using boot drive selection on startup and using uefi/secure boot was frustrating with constant errors, disabled it and no more problems.

Uefi and secure boot are 2 different things (secure boot is 1 specific optional feature offered by uefi). Dual booting SHOULD have secure boot turned off, but use of uefi itself should have negligible effect on dual boot performance.
