Usually, I don't have to fiddle with grub. The cases I remember were
when I had repaired windows installations (in a dual boot situation)
which refused to boot. By restoring the windows boot mechanism via the
rescue console, the MBR had been overwritten, and I had to re-install
grub to get back dual booting; and I did that in the order I had
mentioned: grub2-install first, then grub2-mkconfig. Perhaps the
reversed order might work as well in this use case, but I never tried
that.
I found a very nice utility called boot-repair. I boot from that CD &
it
remakes the boot file including all bootable OSes on the drive(S).
I have fedora booting from sdb & windows booting from sda, and I also
had that issue when I tried to reinstall windows.
