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?
Welcome to ask.fedora. I've removed the inappropriate commercial link from your question. Please don't do things like that again.
@sideburns, don't you think it's strange to install F25 now, when it's almost or completely out of support? Maybe the only reason for the post was the link you've removed?
for anyone reading and thinking this is real "user" asking:
ofcourse it was a bot.. each week a doozend gets removed and silenced ;)
The link was tacked on at the end, almost as an afterthought, which is why I just removed it and didn't ban the poster as a spammer. Let's see if he learns from the experience.
