(grub2-efi will install a proper version of grub圆4.efi which loads the GRUB config from the correct location. Grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg So I installed grub2-efi, created a new config file (just to be sure) and the boot was fixed! dnf install grub2-efi But the GRUB problem was not yet resolved: I only booted when issuing the “configfile” command manually.Ĭause of this problem was the: grub2-install command (as one could have read at the link mentioned earlier!): EFI + grub2-install don’t go well, I one can trust the red box in the Fedora wiki article. Grub> configfile (hd0,gpt)/EFI/fedora/grub.cfgĪt this stage I was able to boot my Fedora instance, again. I decided to load my existing config file EFI/fedora/grub.cfg (on the EFI partition) manually: It seemed like GRUB did not find its configuration file. Unfortunately I haven’t read … and made things … worse and better and the same time? …Īfter “restoring” grub圆4.efi the boot process took me to GRUB (at least), but stopped at the GRUB command prompt: To install GRUB on my SSD and restore that. It seemed clear to me that I needed to run grub2-install -efi-directory=/boot/efi -target=x86_64-efi /dev/nvme0n1 Though, when I was busy with my repair, I obviously missed to install grub2-efi-圆4 so I ended up with this message after a reboot:įailed to open \EFI\fedora\grub圆4.efi - Not Foundįailed to load image \EFI\fedora\grub圆4.efi: Not Found Run this command to reinstall all the important boot related packages that were removed by accident: dnf reinstall grub2-efi grub2-pc grub2-pc-modules grub2-tools-efi grub2-tools-extra shimĪnd that’s basically it! Your system should be fine, again.Įxit the chroot, unmount all the drives and reboot: exit You might get an idea why my system stopped booting successfully … -) Reinstall GRUB and Shim The list includes the following packages: grub2-efi-圆4-1:2.86_64 In /var/log/dnf.log I found the list of packages that was removed during the dnf autoremove and copied the section to a new text file. … check if resolving public names does work, now: ping (… or select another DNS resolver IP address. Now put the following into /etc/nf nameserver 9.9.9.9 I replaced it like this: mv /etc/nf /etc/ While pings should work, sometimes DNS resolving does not work due to a broken / invalid /etc/nf. Your network connection inside the chroot will probably not work as it should. You are now effectively in your old Fedora system - not in the live system, anymore! You can exit the chroot environment via exit. The final step to change to the existing Fedora system: chroot /mnt/sysimage Mount /dev/nvme0n1p3 /mnt/sysimage/boot/efi Mount /dev/mapper/fedora_thomas-nb2-root /mnt/sysimage mkdir /mnt/sysimageĬryptsetup luksOpen /dev/nvme0n1p3 cryptdata

I booted up the live medium and set up a wired network connection.
Repair grub2 windows 10 manual#
The following steps are similar to the ones described on this Fedora Manual page: … What went wrong? As always with a non-booting system, a live system on a USB dongle helps… Chroot Fedora in Live environment My laptop was not even able to start any boot loader - it booted straight to the device diagnosis application that the hardware manufacturer ships. Unfortunately some really important packages (amongst some legacy packages) were removed. I intended to remove dangling packages from my system - expecting my package manager to know which packages are needed and which not. This time the accident was caused by a simple dnf command: dnf autoremove Last time that happened was ~ 4 years ago when Arch Linux could not decrypt my main partitions due to some changes on a crypto library. It happened again - this time on my Fedora machine! I ended up with a laptop that won’t boot after some package changes.
