Create a USB stick using any Fedora netinstaller, boot and choose the Troubleshooting menu, and in that submenu is an option to Rescue a Fedora system. Choose that. There will be an option to locate and assemble Fedora, do that. And then at the shell: # chroot what's next depends on whether you have UEFI or BIOS firmware: Reinstalling GRUB itself https://docs.fedoraproject.org/en-US/Fedora/25/html/System_Administrators_Guide/sec-Reinstalling_GRUB_2.html https://docs.fedoraproject.org/en-US/Fedora/25/html/System_Administrators_Guide/sec-grub2-reinstall_on_UEFI-Based_Machines.html Rebuilding grub.cfg is in step 4 here, pick one of the two commands listed, depending on firmware type. https://docs.fedoraproject.org/en-US/Fedora/25/html/System_Administrators_Guide/sec-Resetting_and_Reinstalling_GRUB_2.html You can do this with any Fedora netinstaller. The version doesn't matter. > > I wanted to repair/upgrade the F23 install with F25.

Basically they want a completely clean file system before starting an installation. The partial exception is Btrfs, which doesn't need reformatting, but will require a new subvolume created for the new root fs. The installer will do that automatically. > > The Fedora documentation that I find says that the Live CD/DVD does > not support doing an upgrade, I need to use a bootable DVD.

Replace, yes. You'll need to specify which partitions to reformat or delete.

No, you have to fix it before it can be upgraded. -- Chris Murphy _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
