Hi,
I made a PC with SSD and AMD Ryzen processor.I partitioned SSD for about 40% for win10 and the rest for Fedora.
Win10 installed OK.
After I installed Fedora32 I lost grub entry for Win10.

Here is mi fsdisk -l output:

I tried
grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg

but didn’t help, so I erased it.
Can someone help me with this issue?

Hello there and Welcome to Ask Fedora.

grub2-mkconfig uses a program called os-prober to detect other operating systems. Install os-prober and then rerun the grub2-mkconfig line that you posted. I THINK that will allow grub2-mkconfig to detect Windows 10 and add it to to the grub boot menu.

os-prober already installed and did’t find win10
I believe that I’ll have to do it manually but don’t know how.
