How to safely install GNU/Linux distro on a Samsung UEFI enabled laptop

I have already bricked and replaced my Samsung Chronos Series 7 NP700Z3C laptop. I have discussed it in the following question:

Why does my Samsung Chronos 7 not boot anymore after installing Ubuntu?

Summary of the problem is that If you normally try to install Linux on it, your laptop will die.

I am a GNU/Linux user and I boot and install different distributions frequently. Now I want to know how I should deal with this laptop, should I always be afraid to boot a live GNU/Linux distro on it? Or is there a safe way to avoid this problem again?

Thanks.


The Samsung UEFI bug is not Linux-specific -- as described by Matthew Garrett, it can be triggered under Windows, too. Disabling UEFI support in the laptop is the safest way to deal with it, but this will require re-installing Windows, and the installation media provided by Samsung probably don't support doing a BIOS-mode install. Thus, you may need to find installation media from another source. Personally, I'd return the laptop to the store for a refund and buy another brand, but if that's not an option, converting everything to BIOS mode is the safest (albeit awkward) solution.

With any luck Samsung will eventually release a fixed firmware, but I have no idea how long this will take to appear.


Set the laptop to boot in BIOS/legacy mode/Compatibility Support Module (there should be some option somewhere) and you should be fine. Just don't boot it going the UEFI route.


According to this article and to committed patch to Linux kernel, most reliable way to avoid this is to disable UEFI mode - this patch simply disables boot if UEFI mode is detected to prevent possible bricking.
