The Solution:
01. Boot a live fedora cd or dvd
02. mount your on-disk fedora linux on .... say /fedora, like so:
mkdir /fedora
mount /dev/sd?? /fedora # where ?? is the disk and partition
where your
fedora is installed.
03. tar cf - dev | tar -C /fedora -xpvf -
04. chroot /fedora
05. grub2-install --recheck /dev/sd??
06. grub2-mkconfig -o /etc/grub2.cfg
When the command (at point 8) returns, then
07. cd /dev
08. rm -rf *
Why? because /dev/ is populated dynamically at boot time.
Let the list know how it went.
_______________________________________________
This tar+rm business with dev looks confusing and dangerous. Use bind
mounts to place the virtual filesystems in the chroot path.
