2. Be civil
- Understand the difference between a joke and an insult.
- Do not harrass or attack members of the community for any reason.
- Leave remarks of "peasantry" to the PCMR community. If you dislike an OS/service/application, attack the thing you dislike, not the individuals who use it. Some people may not have a choice.

- These rules are somewhat loosened when the subject is a public figure. Still, do not attack their person or incite harrassment.
3. Post Linux-related content
- Including Unix and BSD.
- Non-Linux content is acceptable as long as it makes a reference to Linux. For example, the poorly made mockery of
sudoin Windows. - No porn. Even if you watch it on a Linux machine.
4. No recent reposts
- Everybody uses Arch btw, can't quit Vim, and wants to interject for a moment. You can stop now.
Please report posts and comments that break these rules!
Important: never execute code or follow advice that you don't understand or can't verify, especially here. The word of the day is credibility. This is a meme community -- even the most helpful comments might just be shitposts that can damage your system. Be aware, be smart, don't fork-bomb your computer.

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?
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
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.
