New blog post from me: I Stubbed My Bootloader And Lived To Tell The Tale

It all started when a man with a gun sent my laptop flying, while we were travelling at over 100 miles per hour…

#MildPeril #Linux #GRUB #EFI #UEFI #EFIBootStub #Arch #btw

Say goodbye to complex #boot #configs. #Tumbleweed’s new default, #GRUB2-BLS, means no config generation, easier encryption with #systemd tools, and a streamlined #EFI setup. Full-disk encryption with #TPM2? Now just a few clicks. #openSUSE https://news.opensuse.org/2025/11/13/tw-grub2-bls/

I think what the #OpenBSD installer does was simply create the openbsd directory in #EFI partition and copy boot.efi files there. Additionally it probably also copy these files to the boot dierectory there, which makes openbsd the default #UEFI boot entry. However, if you want to change boot entry orders, for example for your four different systems, you will have to go to BIOS settings. OpenBSD is not able to handle that, #efibootmgr in #Linux and #FreeBSD is for this task.

These always crack me up. #itfailsusa #efi #Airports

I should find the picture that I took of one of the ordering terminals in #Argos the other day that was stuck at the EFI Shell prompt.

Recently started having rEFInd (actually, I think the EFI BTRFS driver) fail to load the kernel ("Not Found"). Infuriating since the kernel works in other filesystems (even BTRFS ones!) and some kernels work fine.

Not sure how to debug.

@venande mach mal ein Kommandozeilenfenster auf (Ctrl+T) und gib
df -h
ein. Danach
inxi -Fz
und kopiere das Angezeigte hier rein.

Zeigt Dir gparted irgendeine Fehlermeldung auf /dev/sda?

Ist es ein BIOS- (MBR zerschossen?) oder ein UEFI-Rechner (efi-Partition kaputt?)?

Booting Debian13 installer on Mac. Funny thing is that I don't run this new Debian on any of my other machines yet.

Has anyone made any purchases from chipsetpro.com? They are the only ones I can find that sell EFI ribbon cables. #mac #efi #flash

@garyhtech The size of the old "/boot/efi/boot/bootx64.efi" was in excess (~646 kB) of replacement "boot1.efi" (~150 kB). Did that not concern you?

# On v14.3 system.
zsh
stat -f "%z %N" /boot/{boot?.efi,loader.efi} /boot/efi/efi/{boot/bootx64.efi,freebsd/loader.efi}

675328 /boot/loader.efi
674816 /boot/efi/efi/boot/bootx64.efi
674816 /boot/efi/efi/freebsd/loader.efi

(~500 B difference had me update ~year old boot loader as it was sticking out)

Operation not permitted probably because the ESP-related mount was unnecessary (it already existed).

Check the default /etc/fstab

This 2021 commit might be the milestone first of a series of commits that simplified things:

Last Week on My Mac: The quiet firmware revolution

https://web.brid.gy/r/https://eclecticlight.co/2025/10/19/last-week-on-my-mac-the-quiet-firmware-revolution/

<p>The most worrying feature of the current AI ‘revolution’ is how heavily it’s being promoted by everyone from vibe coders to governments. The best and most enduring revolutions are quiet, and bring change because they’re so compelling. If something new has to be heavily evangelised, look deeply inside it to discover why, and who stands to gain most from that snake-oil.</p>
<p>In the case of Mac firmware, change has been so underplayed that you might not have realised what has happened over the last decade. But Macs have gone from impending disaster in Thunderstrike 2 with many running old firmware known to be vulnerable, to Secure Boot and thoroughly reliable updates.</p>
<p>In 2015 Trammell Hudson, Xeno Kovah and Corey Kallenberg demonstrated a firmware worm they named <a href="https://trmm.net/Thunderstrike2_details/" target="_blank">Thunderstrike 2</a> that could have been abused to insert malware in boot flash storage in Macs. Had that been exploited it would have been disastrous. Apple acted quickly by hiring Kovah and Kallenberg, and a third firmware security researcher Nikolaj Schlej, but shortly after that Rich Smith and Pepijn Bruienne, then of Duo Labs, reported that many Macs were running outdated firmware. When Apple addressed Thunderstrike 2 it could thus have taken a year or more before most Macs would have been protected.</p>
<p>While Kovah, Kallenberg and Schlej were busy securing firmware, and developing <code>eficheck</code> to rout

If I have two EFI partitions in different disk, why can't BIOS be smart enough to use secure boot on Windows partitions, do I have to go switch the settings in BIOS always?
