Ask away: http://ask.fedoraproject.org Thanks for the answer! I did upgrades before, but now I'm at F20, so 3 upgrades over 3 computers would take some time. I used to - mount the iso on some empty directory, - extract vmlinuz and the initramfs image for the new distribution and put them in /boot - modify grub.conf accordingly, write it to disk and boot the new kernel - during install, specify the partition and the path to the iso of the new fedora. I guess this is along the lines of what you suggested, but I have no idea what UEFI is. I didn't find any reference to anything like this in the install instructions for recent versions like F22 or F23. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: http://lists.fedoraproject.org/admin/lists/users@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
