As I type this, I'm installing Fedora 20 on a UEFI system which already has CentOS 7 (and nothing else). Should the two systems share /boot/efi? As I understand it, the answer is yes: /boot/efi is universal on a machine. It is where the firmware goes to load things. Not just OS bootloader: manufacturer-supplied EFI utilities can live there too. But Fedora, by default, wants to create a new /boot/efi. What is the right thing to do? What will work? In the current installation, I've forced Fedora to use the existing /boot/efi. I guess I'll see how that turns out. I could not see any guidance in the Fedora 20 installation guide. <https://docs.fedoraproject.org/en-US/Fedora/20/html/Installation_Guide/s1-diskpartitioning-x86.html> In fact, the appendix on disk partitions didn't deal with EFI/UEFI/GPT, something I could have used. (After 20 years of living with MBR, I kind of got the hang of it.) -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
