You can even delete your efi partition and brick your board
Edit: I mean delete your efivars
Deleting your efi partition doesn't brick your board. It just makes your disk unbootable, but you can always install another operating system and create a new efi partition.
I think you're confusing with the special
efivarfsfile system that is mounted under/sys/firmware/efi/efivars. If you delete stuff under there, you're apparently going to have a bad time, because it directly deletes variables in your UEFI firmware which can prevent your system to POST.Ah yes. I always confuse them. I even though that what I wrote didn't make any sense since usually I know what an efi partition is. Thanks for correcting me
EFI is on the hard drive. No bricking. You just need to reformat to include it again.
Ya wanna brick a mobo? Botch a flash to the bios chip.
No, you can brick the mobo from your OS by deleting the efivar partition.
If your talking about /sys/firmware/efi/efivars?
Yeah. You realize that’s on the bios chip? The efi partition on the hard disk is a different thing.
When a system posts, the main drive isn’t mounted. The mobo needs to go look for it. The bios actually holds the instructions on how to post and start the system. (The efivar are part of that.)
One step in that process is to look for the efi bootloader on the drive. That is the efi partition that won’t brick anything.
Alterations to the bios chip will, if they’re not done carefully. This is why it’s almost unheard of to flash a firmware update on consumer systems
My work laptop does this automatically. It's a Dell laptop btw
