I have installed Fedora in Dual boot along with windows however i wanted to be able to boot into the last used OS and so, i installed GRUB Customizer a GUI tool for grub and After Restart fedora was no longer listed on GRUB. I cant get into fedora again and is there anyway to reverse this?
You could use live iso usb, and then
chroot it. Please read this Fedora Magazine. Also don’t forget to mounting
/boot/efi so when you inside the
chroot, you got
# Backup your current grub.cfg file. mv /boot/efi/EFI/fedora/grub.cfg /boot/efi/EFI/fedora/grub.cfg.bak mv /boot/grub2/grub.cfg /boot/grub2/grub.cfg.bak # Reinstall grub dnf reinstall shim-* grub2-efi-* grub2-common
chroot and run
efibootmgr -v and check you have line
/File(\EFI\fedora\shimx64.efi) as bellow.
Boot00XX Fedora HD(1,GPT,<any-gpt-number>)/File(\EFI\fedora\shimx64.efi)
Reboot, and try to booting to your installed Fedora.
