Patrick Wu :neocat_flag_bi:Fedora 42 is kinda messing with my mind right now... the GRUB2 entry all become "Fedora Linux 42 (Workstation Edition)" without Kernel version... After some investigation, realized on line 192 in `/usr/lib/kernel/install.d/90-loaderentry.install`, for all kernel entries generated to /boot/loader/entries/, it only uses $PRETTY_NAME from /etc/os-release for $title while GRUB2 loads only the $title... after modifying the title, it finally went normal...<a href="https://o0o.social/tags/linux" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#linux</a> <a href="https://o0o.social/tags/fedora" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#fedora</a> <a href="https://o0o.social/tags/grub2" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#grub2</a> <a href="https://o0o.social/tags/grub" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#grub</a>

Saemon ZixelUEFI оказалась не такой уж и сложной технологией.Оказывается, можно просто создать раздел FAT32 с типом ef, сделать его активным, создать там папку EFI, а в ней BOOT. И положить туда grubx64.efi переименовав его в bootx64.efi. И при перезагрузке прошивка EFI материнской платы сама найдёт этот раздел, залезет в папку EFI/BOOT и загрузит и запустит bootx64.efi. И появится командная строка GRUB2.Если подложить в правильное место grub.cfg, то появится меню, а не командная строка.Поскольку я использовал для экспериментов GRUB из ubuntu, то в нём был захардкожен путь /EFI/ubuntu. Соответственно, туда и пришлось класть grub.cfg и grubenv (для удобства).Но это при условии, если в NVRAM переменные BOOT001, BOOT002 и т.д. отсутствуют или ведут к несуществующим или поломанным загрузчикам. UEFI в первую очередь пытается загрузить файлы загрузчики из этих переменных.Можно ещё распаковать в EFI раздел rEFInd, который может загружать разные операционные системы в режиме EFI. А поскольку он основывается на GRUB2, тоже умеет напрямую грузить ядро linux.<a href="https://lor.sh/tags/uefi" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#uefi</a> <a href="https://lor.sh/tags/efi" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#efi</a> <a href="https://lor.sh/tags/grub2" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#grub2</a> <a href="https://lor.sh/tags/refind" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#refind</a> <a href="https://lor.sh/tags/devops" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#devops</a> <a href="https://lor.sh/tags/linux" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#linux</a>
