Installing Fedora and preserving Grub

I installed Fedora 24 3 times last year.

Each times, Fedora ended up overwriting previous Grub with its own without asking. I don't even know during which part of the installation it did that.

This was not supposed to create any problems, but on a multiple boot including a Windows installed with the UEFI (I didn't want that…), I wasn't able to access my Windows at all after that.

I want to install Fedora 25 but I want to be sure it will not reinstall its own Grub.

Can I have tips to avoid that?

Solution

  • Thanks to @rickhg12hs, I found the installation documentation here: https://docs.fedoraproject.org/en-US/Fedora/25/html/Installation_Guide/sect-installation-gui-storage-partitioning.html

    During partitionning, there's a link at the bottom of the page I didn't notice a single time, just here (on an old Fedora installer, not mine): Bootloader configuration

    I disabled the installation of the bootloader on my disk and everything went well.

    The only reproach I can make is the link not really obvious even after reading steps explained in the documentation.
