WARNING:

Don't ever do this on a current bare metal system!
Even if you have everything backed up, plan on re-installing anyway, and just want to see what happens.

On a modern EFI system, recursively deleting everything (including the EFI path) has a chance of permanently hard-bricking your computer!

Why would it be a permanent brick? Shouldn't a flashdrive and access to BIOS be enough to get your PC working again?

[-] superkret@feddit.org 1 points 1 month ago* (last edited 1 month ago)

In a properly implemented EFI, this should be possible. But there have been cases with improperly implemented EFI in some laptops/motherboards where the computer won't POST after /sys/firmware/efi/efivars/ was nuked. In that case, accessing BIOS or booting from a flashdrive isn't possible anymore.

I have a little flash chip reader and backed up my bios and can flash it on the laptop. Even modified it to unlock the advanced menus Lol

But th rm rf thing didn't nuke it so I guess I'm safe either way

Bro, BIOS is located on motherboard and EFI variables only needed to boot an OS.

Just install bootloader and OS in drive

Bro, several people bricked their pc that way. I'm no expert, just throwing out a warning not to do dumb shit.

But Windows 95/XP does not run on EFI systems, so they aren't used in the BRD. We're save!

Plus no ads, and MUCH more efficiently written code to boot - win-win!

Just don't hook it up to the Internet...

We only need fax anyway. So we print stuff out, and fax it.
