It sounds like you are throwing mud at the wall, and hoping something will stick. That's a recipe for disaster when troubleshooting computer systems. Calm and methodical, that's the way. I know only a little about UEFI booting, though I recently got it working. My understanding is that there can be only one default uefi /boot/efi. So, if you wanted the second system installed to be bootable directly, you should have created a /boot/efi for the second install on the disk where it was installed. You then could use the firmware boot selection to switch to the alternate if the default isn't what you want. I *think* the last installed uefi system is the default in the firmware. Do you have a rescue CD / USB stick you can boot from? You can then mount /mnt/sysimage for the system you want to repair, and chroot there to do your repairs. I think you need to re-install the shim and grub-efi. e.g. dnf reinstall grub2-efi shim-ia32 shim-x64 That system will then be the default boot for uefi. You should probably run grub2-mkconfig -o grub.cfg in /boot/efi/EFI/fedora after you do the reinstall. That should give you a bootable system to work from. This is a little out of date, but has useful information. It says there that grub-install will render a uefi system unbootable, which is your experience. https://superuser.com/questions/596317/how-would-i-reinstall-the-grub-efi-bootloader-on-fedora-linux Here's the official Fedora uefi docs. https://docs.fedoraproject.org/en-US/Fedora/18/html-single/UEFI_Secure_Boot_Guide/index.html#sect-UEFI_Secure_Boot_Guide-Tools-shim _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
