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. http://sourceforge.net/projects/boot-repair-cd/

You may avoid to do it. But I have a multiboot system. I may have to manage which grub.cfg file needs to be read when booting. grub-install let me do it. =========================================================================== Patrick DUPRÉ | | email: pdupre(a)gmx.com Laboratoire de Physico-Chimie de l'Atmosphère | | Université du Littoral-Côte d'Opale | | Tel.

Hello, After I run grub2-mkconfig -o /boot/grub2/grub.cfg grub2-install /dev/sda

Hello, In my opinion, it odes not matter. after grub-install /dev/sda grub knows that it has to read the file /boot/grub2/grub.cfg Then you can change it, it will use the chnaged file. There is no copy of the copy in /dev/sdx =========================================================================== Patrick DUPRÉ | | email: pdupre(a)gmx.com Laboratoire de Physico-Chimie de l'Atmosphère | | Université du Littoral-Côte d'Opale | | Tel.
