I have install a system with dual boot

But in grub i cant see windows entry
I have done with ostree fedora and how to fix this so i can get access to windows entry too

I think I saw mention here that you may not be able to dual boot with windows and one of the atomic versions. I have not tested that.

Install and Use Grub Customizer in Fedora Linux that would be something!

Thanks for the link, you saved my day.

Many users have serious problems using grub customizer on fedora.

You can see that by searching this forum for related entries. One example is this one, but there are many related.

Thanks first of all! Strange, I don’t have any problems when I have two Disb.mm
But OK, good to know.
Then I will uninstall
